1
00:00:05,138 --> 00:00:09,608
[Pamela Hofsass] It was clear that whoever
committed the crime was known to her.
2
00:00:09,610 --> 00:00:11,276
And was allowed in by her.
3
00:00:12,312 --> 00:00:13,145
[woman yelling]
4
00:00:14,214 --> 00:00:15,748
Her career was blossoming.
5
00:00:15,750 --> 00:00:17,583
This is my cubicle.
My computer.
6
00:00:17,585 --> 00:00:19,885
She loved life.
Loved her family.
7
00:00:19,887 --> 00:00:22,087
She really was effervescent.
8
00:00:22,089 --> 00:00:23,522
She was quite special.
9
00:00:23,524 --> 00:00:27,393
It had all the hallmarks
of a frenzied assault
10
00:00:27,395 --> 00:00:31,397
with multiple strikes
and a lot of bloodshed.
11
00:00:31,399 --> 00:00:35,234
It seemed to me
like it was a rage killing.
12
00:00:35,236 --> 00:00:36,735
The letter that he read
13
00:00:36,737 --> 00:00:40,072
at the memorial service
stated, "If I killed Lisa..."
14
00:00:40,074 --> 00:00:42,174
It was very, very strange.
15
00:00:42,176 --> 00:00:45,344
The perpetrator stayed
in the house for over 30 hours
16
00:00:45,346 --> 00:00:49,581
and approximately 2 feet
of hair was cut and taken.
17
00:00:49,583 --> 00:00:52,484
[man] Removing her hair
would have just intensified
18
00:00:52,486 --> 00:00:54,620
the killer's
obsessive tendencies.
19
00:00:54,622 --> 00:00:56,588
The need to own her,
even in death.
20
00:00:56,590 --> 00:00:58,957
It was 13 years
since the homicide
21
00:00:58,959 --> 00:01:01,593
and then they said,
"We have a perfect match.
22
00:01:01,595 --> 00:01:03,562
We finally got the guy."
23
00:01:05,698 --> 00:01:07,733
[narrator] Every day
in North America
24
00:01:07,735 --> 00:01:10,269
dozens of people are murdered.
25
00:01:10,271 --> 00:01:12,738
The key to solving the
toughest of these homicides
26
00:01:12,740 --> 00:01:16,608
lies in the final 24 hours
of the victim's life.
27
00:01:16,610 --> 00:01:22,247
To crack the case, detectives
must reconstruct that critical timeline.
28
00:01:22,249 --> 00:01:23,849
The minutes and hours
containing evidence
29
00:01:23,851 --> 00:01:28,720
that can help unlock the
mystery and catch the killer.
30
00:01:37,330 --> 00:01:39,731
[narrator]
San Francisco, California,
31
00:01:39,733 --> 00:01:42,501
sparkles with color
and diversity.
32
00:01:42,503 --> 00:01:45,304
And in the late 1990s,
33
00:01:45,306 --> 00:01:46,905
the upscale neighborhood
of Diamond Heights
34
00:01:46,907 --> 00:01:50,342
is one of the city's
crown jewels.
35
00:01:50,344 --> 00:01:52,511
[Hofsass] San Francisco
is bustling in '98.
36
00:01:52,513 --> 00:01:55,347
And one of the reasons people
move to Diamond Heights
37
00:01:55,349 --> 00:01:59,585
is to see the expansive
view of the city from above.
38
00:01:59,587 --> 00:02:01,720
There is a panoramic
view of the bay.
39
00:02:01,722 --> 00:02:04,223
It was considered a
very safe neighborhood.
40
00:02:04,225 --> 00:02:09,528
No major crimes like you might find in
The Tenderloin or downtown San Francisco.
41
00:02:09,530 --> 00:02:11,563
[narrator]
On a late spring morning,
42
00:02:11,565 --> 00:02:14,199
with the city enveloped
in a layer of fog,
43
00:02:14,201 --> 00:02:16,735
an alarming call comes into 911
44
00:02:16,737 --> 00:02:19,505
from an upscale
condominium complex.
45
00:02:19,507 --> 00:02:23,408
[Hofsass] The manager of one of the
buildings in Diamond Heights Village
46
00:02:23,410 --> 00:02:28,714
noticed a foul odor
coming from condominium 307.
47
00:02:28,716 --> 00:02:31,917
The manager found the door
unlocked, opened the door,
48
00:02:31,919 --> 00:02:35,654
and saw what appeared to
be a deceased individual.
49
00:02:35,656 --> 00:02:38,323
It would be a
fair assumption to say
50
00:02:38,325 --> 00:02:40,759
that he realized something
was terribly wrong.
51
00:02:40,761 --> 00:02:42,594
He immediately
called the police.
52
00:02:42,596 --> 00:02:44,229
[siren blaring]
53
00:02:44,231 --> 00:02:47,666
Police and paramedics arrived
at the scene at 12:20pm
54
00:02:47,668 --> 00:02:51,537
and upon entering they found
a female on the floor.
55
00:02:51,539 --> 00:02:58,410
It was immediately obvious to the
first responders that this was a homicide.
56
00:02:58,412 --> 00:03:01,713
[narrator] The victim
is the owner of the condo,
57
00:03:01,715 --> 00:03:05,751
36-year-old computer
programmer, Lisa Valdez.
58
00:03:05,753 --> 00:03:08,387
Lisa worked in the IT profession
59
00:03:08,389 --> 00:03:10,822
and her career was blossoming.
60
00:03:10,824 --> 00:03:13,058
And this is my cubicle.
61
00:03:13,060 --> 00:03:16,128
My computer that I can
type on the little computer.
62
00:03:16,130 --> 00:03:19,531
Lisa Valdez was born
and raised in San Francisco.
63
00:03:20,767 --> 00:03:22,100
She loved life.
64
00:03:23,436 --> 00:03:25,070
Loved her family.
65
00:03:25,072 --> 00:03:27,372
She really was effervescent.
66
00:03:27,374 --> 00:03:28,974
She was quite special.
67
00:03:33,780 --> 00:03:37,749
[narrator] Inspectors Pam
Hofsass and Ronan Shouldice
68
00:03:37,751 --> 00:03:41,386
from the San Francisco Police
Department's homicide detail
69
00:03:41,388 --> 00:03:43,288
are called in to investigate.
70
00:03:44,757 --> 00:03:47,726
[Shouldice] When you are in
such close proximity
71
00:03:47,728 --> 00:03:52,497
knowing that this person
has been violently murdered,
72
00:03:52,499 --> 00:03:56,668
you can really not stop
the video reel in your mind
73
00:03:56,670 --> 00:04:00,005
imagining the sequence
of events.
74
00:04:00,007 --> 00:04:04,509
Crime scenes, they will reveal
some of the story themselves.
75
00:04:04,511 --> 00:04:09,348
Lisa's body was left in the
position that you could only
76
00:04:09,350 --> 00:04:12,718
describe as being
extremely undignified.
77
00:04:13,686 --> 00:04:16,888
Her shirt was pulled up
around her neck.
78
00:04:16,890 --> 00:04:19,625
Her underwear appeared
to have been torn off
79
00:04:19,627 --> 00:04:21,760
and were
on the floor beside her.
80
00:04:21,762 --> 00:04:25,764
She had a number of stab wounds.
81
00:04:25,766 --> 00:04:28,934
It was really difficult
to discern any wounds
82
00:04:28,936 --> 00:04:30,869
or pattern of wounds,
given that there was
83
00:04:30,871 --> 00:04:34,473
a degree of decomposition
already underway.
84
00:04:34,475 --> 00:04:39,811
It appeared that she had been
deceased for a period of a few days.
85
00:04:42,982 --> 00:04:45,150
[Hofsass] If you look at
the crime scene,
86
00:04:45,152 --> 00:04:48,320
it seems that there is
a very angry outburst.
87
00:04:48,322 --> 00:04:51,390
The way the mattress
is located was very odd.
88
00:04:51,392 --> 00:04:54,126
It appears that the victim
was stabbed on the bed
89
00:04:54,128 --> 00:04:57,329
and then pulled off
the mattress onto the floor.
90
00:04:59,098 --> 00:05:02,267
In this case, the blood
at the scene tells us a lot.
91
00:05:02,269 --> 00:05:04,736
When you see a lot of
high-velocity splatter,
92
00:05:04,738 --> 00:05:08,206
this suggests that someone
has been struck or stabbed
93
00:05:08,208 --> 00:05:10,008
with tremendous speed and force
94
00:05:10,010 --> 00:05:11,777
and is casting blood
a great distance.
95
00:05:11,779 --> 00:05:15,414
It suggests that this is very
much a frenzied attack,
96
00:05:15,416 --> 00:05:17,382
some kind of crime of passion.
97
00:05:21,621 --> 00:05:24,089
[narrator] To solve
Lisa Valdez's murder,
98
00:05:24,091 --> 00:05:28,360
detectives will need to reconstruct
the final 24 hours of her life.
99
00:05:28,362 --> 00:05:30,195
[Lisa screaming, straining]
100
00:05:30,197 --> 00:05:33,498
There was a bed which
was in disarray,
101
00:05:33,500 --> 00:05:37,202
with a large quantity of blood.
102
00:05:37,204 --> 00:05:42,107
Blood all over. Basically, the mattress
is soaked, the bedding is soaked.
103
00:05:42,109 --> 00:05:45,577
So maybe it was a
sexual encounter gone bad.
104
00:05:46,979 --> 00:05:50,215
[Shouldice] The injuries were
clearly the result of stabbing
105
00:05:50,217 --> 00:05:53,852
using some kind of weapon,
given the degree of bloodshed.
106
00:05:53,854 --> 00:05:57,589
The working assumption was
that it was an edged weapon.
107
00:05:57,591 --> 00:05:59,891
A knife of some sort.
108
00:05:59,893 --> 00:06:03,028
[narrator] Detectives collect
all the bedding for testing,
109
00:06:03,030 --> 00:06:06,331
hoping some of the blood
belongs to Lisa's killer.
110
00:06:06,333 --> 00:06:08,633
[Shouldice] Particularly in an
edged weapon attack
111
00:06:08,635 --> 00:06:10,435
where there is often
a high likelihood
112
00:06:10,437 --> 00:06:14,539
that the assailant will likewise
injure himself or herself.
113
00:06:15,675 --> 00:06:17,509
[Hofsass] If you
stab someone repeatedly,
114
00:06:17,511 --> 00:06:19,811
your fatty palm of your hand
115
00:06:19,813 --> 00:06:22,180
is going to get wet
with the blood of that victim
116
00:06:22,182 --> 00:06:24,449
and then you will
start hitting the hilt
117
00:06:24,451 --> 00:06:27,652
and the blade with your palm
as you are stabbing someone.
118
00:06:29,522 --> 00:06:34,626
[narrator] Inspectors continue processing
the crime scene looking for answers.
119
00:06:34,628 --> 00:06:36,895
[Shouldice] Beside Lisa's body
on the carpet,
120
00:06:36,897 --> 00:06:39,664
there was also a broken glass.
121
00:06:39,666 --> 00:06:44,603
This broken glass, perhaps it may
have been held by her assailant.
122
00:06:44,605 --> 00:06:48,740
There was a phone beside the bed
with the receiver knocked off the base.
123
00:06:48,742 --> 00:06:50,675
There was blood on it.
124
00:06:50,677 --> 00:06:56,481
Everything was collected for both
the DNA and latent fingerprints.
125
00:06:56,483 --> 00:07:01,153
[narrator] Investigators collect Lisa's
computer, agenda, and answering machine
126
00:07:01,155 --> 00:07:05,490
hoping they'll offer up clues on
who might have wanted to kill her.
127
00:07:05,492 --> 00:07:11,663
We collect these items attempting to
establish recent contacts and activity.
128
00:07:11,665 --> 00:07:14,199
[Hofsass] If you looked
at her calendar,
129
00:07:14,201 --> 00:07:17,002
almost every hour
of every single day
130
00:07:17,004 --> 00:07:19,704
was filled with some
event or celebration,
131
00:07:19,706 --> 00:07:22,107
either a date or a gym workout.
132
00:07:22,109 --> 00:07:25,410
Hawaiian dance class.
I mean, she did it all.
133
00:07:25,412 --> 00:07:28,980
So she was very, very active.
134
00:07:28,982 --> 00:07:33,185
[Shouldice] Then the search continued
throughout the rest of the condominium.
135
00:07:33,187 --> 00:07:36,588
The bathroom
became an area of focus
136
00:07:36,590 --> 00:07:40,859
because it seemed clear to me that the
assailant had spent some time in there.
137
00:07:40,861 --> 00:07:42,694
Most significantly to me,
138
00:07:42,696 --> 00:07:45,197
the toilet seat
was in the raised position.
139
00:07:45,199 --> 00:07:46,865
[Hofsass] Lisa lives alone.
140
00:07:46,867 --> 00:07:48,867
Most women don't leave
the toilet seat up.
141
00:07:48,869 --> 00:07:50,902
We don't go to
the bathroom that way.
142
00:07:50,904 --> 00:07:53,805
[Shouldice] We recovered
a partial latent fingerprint
143
00:07:53,807 --> 00:07:57,476
consistent with where
an individual's fingers
144
00:07:57,478 --> 00:08:04,049
may go underneath to raise it
into the up position.
145
00:08:04,051 --> 00:08:10,789
Other surfaces also yielded prints or
partial prints all of which were collected.
146
00:08:10,791 --> 00:08:12,791
[narrator] New questions
emerge as investigators
147
00:08:12,793 --> 00:08:16,461
work their way
through Lisa's condo.
148
00:08:16,463 --> 00:08:19,297
At the scene, you have
to look at everything.
149
00:08:19,299 --> 00:08:22,033
Was this a burglary gone wrong?
150
00:08:22,035 --> 00:08:24,536
There was nothing
to indicate that somebody had,
151
00:08:24,538 --> 00:08:27,606
either before or after
the homicide,
152
00:08:27,608 --> 00:08:31,743
searched through Lisa's unit
looking for valuables.
153
00:08:31,745 --> 00:08:34,746
It was a very secure building.
154
00:08:34,748 --> 00:08:40,185
You had to be admitted or to
have codes to access the building.
155
00:08:40,187 --> 00:08:42,420
There was a door viewer
in the door
156
00:08:42,422 --> 00:08:44,789
which would allow her
to see who was outside.
157
00:08:44,791 --> 00:08:47,592
[Hofsass] There's no sign
of forced entry.
158
00:08:47,594 --> 00:08:50,295
It was clear that whoever
committed the crime
159
00:08:50,297 --> 00:08:55,066
was known to her and was
allowed in by Lisa Valdez.
160
00:08:55,068 --> 00:08:59,771
[narrator] Having determined that Lisa
has likely been deceased for several days,
161
00:08:59,773 --> 00:09:01,673
inspectors turned to
her neighbors
162
00:09:01,675 --> 00:09:05,377
hoping to narrow
down her window with death.
163
00:09:05,379 --> 00:09:08,380
Downstairs neighbors report
they heard a commotion
164
00:09:08,382 --> 00:09:12,817
at around 1:26 in the morning
of Sunday, May 17.
165
00:09:12,819 --> 00:09:17,722
It could be as she is being pulled off the
mattress and, you know, lands on the floor.
166
00:09:17,724 --> 00:09:21,860
It could be when she's
being stabbed to death.
167
00:09:21,862 --> 00:09:23,995
[narrator] Based on
this new information,
168
00:09:23,997 --> 00:09:27,165
inspectors believe
that Lisa was likely murdered
169
00:09:27,167 --> 00:09:29,367
around 1:26 a.m.
170
00:09:33,339 --> 00:09:36,041
Investigators turn
to the medical examiner,
171
00:09:36,043 --> 00:09:39,511
hoping their findings will help
them build a profile of the killer.
172
00:09:39,513 --> 00:09:41,880
[Hofsass] The medical examiner
173
00:09:41,882 --> 00:09:44,182
noted a total of 21 stab wounds
174
00:09:44,184 --> 00:09:46,751
to the face, the neck,
and the chest.
175
00:09:47,820 --> 00:09:51,489
They also noted
that the aorta was severed,
176
00:09:51,491 --> 00:09:55,293
which explains the amount of blood
on the mattress and the bedding.
177
00:09:55,295 --> 00:09:58,129
And they also noted defensive
wounds on her hands,
178
00:09:58,131 --> 00:10:01,299
so she probably put her
hands up for self-defense.
179
00:10:01,301 --> 00:10:02,867
[Lisa screaming]
180
00:10:02,869 --> 00:10:05,804
[Shouldice] It had all the
hallmarks of a frenzied assault
181
00:10:05,806 --> 00:10:10,108
with multiple strikes
and a lot of bloodshed.
182
00:10:10,110 --> 00:10:13,478
[Arntfield] Twenty-one
separate stab wounds is overkill.
183
00:10:13,480 --> 00:10:16,381
The fact that most of these
horrific stab wounds
184
00:10:16,383 --> 00:10:18,883
are concentrated around
Lisa's face and chest
185
00:10:18,885 --> 00:10:22,187
tells me that this was not
only intensely personal,
186
00:10:22,189 --> 00:10:27,492
but that this was someone who wanted
to absolutely erase her. Not only kill her.
187
00:10:28,661 --> 00:10:31,830
And there is some type of
possessive, obsessive,
188
00:10:31,832 --> 00:10:35,467
and often sexual
underlying motive.
189
00:10:35,469 --> 00:10:38,036
[Shouldice] Because of
the degradation of DNA,
190
00:10:38,038 --> 00:10:42,307
the medical examiner couldn't prove
that there was also rape involved.
191
00:10:42,309 --> 00:10:46,478
But again, she was left in a
position that would be consistent
192
00:10:46,480 --> 00:10:48,780
with some kind
of a sexual assault,
193
00:10:48,782 --> 00:10:50,649
most likely postmortem.
194
00:10:52,151 --> 00:10:55,720
[narrator] The medical examiner
makes another important discovery.
195
00:10:55,722 --> 00:11:00,458
Lisa's hair appears to have been
crudely cut, most likely postmortem
196
00:11:00,460 --> 00:11:02,961
as there are no
lacerations to her scalp.
197
00:11:04,764 --> 00:11:07,766
[Stockdale] The fact that Lisa
is found with their hair cut off,
198
00:11:07,768 --> 00:11:11,102
this is something that is
fantasy ritualistic-driven,
199
00:11:11,104 --> 00:11:13,605
because cutting
someone's hair is not required
200
00:11:13,607 --> 00:11:15,573
for commission of this crime.
201
00:11:15,575 --> 00:11:18,576
It could very well be
that the killer is motivated
202
00:11:18,578 --> 00:11:21,613
to have a piece of her
always with him.
203
00:11:25,818 --> 00:11:28,420
[narrator] Inspectors
receive the crime lab reports
204
00:11:28,422 --> 00:11:32,390
and the initial findings
don't yield any DNA results.
205
00:11:32,392 --> 00:11:35,393
Fingerprint analysis
also comes up empty.
206
00:11:35,395 --> 00:11:38,730
But then they receive
a potential new lead.
207
00:11:40,066 --> 00:11:43,368
In one particular area on one
of the pillowcases,
208
00:11:43,370 --> 00:11:48,006
there were a couple of drops that
caught the attention of the crime lab.
209
00:11:48,008 --> 00:11:52,077
They felt very optimistic that it
could be the assailant's blood.
210
00:11:52,079 --> 00:11:54,079
And it was.
211
00:11:54,081 --> 00:11:58,750
[Hofsass] We found a mixture of
two different DNAs on the pillow.
212
00:11:58,752 --> 00:12:03,188
One was Lisa Valdez and one
was a unknown male profile.
213
00:12:03,190 --> 00:12:06,758
This blood droplet was a major
breakthrough for the case.
214
00:12:06,760 --> 00:12:10,295
That DNA profile needs to
be matched to somebody,
215
00:12:10,297 --> 00:12:12,464
because he must be the killer.
216
00:12:14,133 --> 00:12:15,800
[narrator]
In the brutal murder
217
00:12:15,802 --> 00:12:19,571
of 36-year-old computer
programmer, Lisa Valdez,
218
00:12:19,573 --> 00:12:22,006
investigators have
their first big break.
219
00:12:22,008 --> 00:12:27,278
They have found male DNA,
possibly from her killer.
220
00:12:27,280 --> 00:12:30,482
I personally hand-delivered a
small, little tube of DNA extract
221
00:12:30,484 --> 00:12:33,785
from this droplet
on Lisa's pillow
222
00:12:33,787 --> 00:12:38,490
that revealed a unknown male
profile to the state DNA crime lab.
223
00:12:38,492 --> 00:12:42,660
Now, In 1998, early DNA
methods took a lot of time,
224
00:12:42,662 --> 00:12:45,330
but they uploaded it to the
database which was very small
225
00:12:45,332 --> 00:12:48,133
and limited at the time
and found no match.
226
00:12:48,135 --> 00:12:52,937
[narrator] With no concrete
leads or potential suspects,
227
00:12:52,939 --> 00:12:56,207
inspectors turned to Lisa's
mother, Helen Valdez,
228
00:12:56,209 --> 00:13:00,044
hoping she can fill out her
daughter's time-line.
229
00:13:00,046 --> 00:13:03,481
[Hofsass] Helen and Lisa
were very close.
230
00:13:03,483 --> 00:13:05,250
They spent
a lot of time together.
231
00:13:05,252 --> 00:13:07,485
They would talk
almost every day.
232
00:13:07,487 --> 00:13:11,556
It was very, very painful
for Helen to lose her daughter
233
00:13:11,558 --> 00:13:13,958
and not know why
someone would do that.
234
00:13:13,960 --> 00:13:18,363
It was just a real heartbreak
for her. As for any parent.
235
00:13:18,365 --> 00:13:22,667
[narrator] Investigators ask Helen
Valdez about her last contact with Lisa.
236
00:13:22,669 --> 00:13:25,003
And learned they saw each other
237
00:13:25,005 --> 00:13:28,373
just a few hours
before Lisa was likely killed.
238
00:13:30,142 --> 00:13:33,812
Lisa's mother said that
on Saturday, May 16,
239
00:13:33,814 --> 00:13:38,216
Lisa entertained her mother
and some friends at a dinner party.
240
00:13:38,218 --> 00:13:40,185
Most of the other guests
were leaving
241
00:13:40,187 --> 00:13:42,387
at about 11:00 p.m.
242
00:13:42,389 --> 00:13:45,890
Helen stays on with
Lisa for another little while
243
00:13:45,892 --> 00:13:50,962
and left around midnight or
12:00 a.m. on Sunday, May 17th.
244
00:13:52,932 --> 00:13:55,567
[narrator] Helen Valdez
also reveals a crucial detail
245
00:13:55,569 --> 00:13:57,435
about her daughter's appearance.
246
00:13:58,804 --> 00:14:00,238
As part of the autopsy,
247
00:14:00,240 --> 00:14:03,708
the medical examiner noted
that her hair was shoulder length
248
00:14:03,710 --> 00:14:07,478
and when that information
was shared with the family,
249
00:14:07,480 --> 00:14:11,916
the response was that Lisa's
pride and joy was her hair.
250
00:14:11,918 --> 00:14:16,120
[Shouldice] They called it, I believe,
her crowning glory. It was her signature.
251
00:14:16,122 --> 00:14:18,590
Helen said that she would
never have cut her hair.
252
00:14:19,959 --> 00:14:23,528
[Hofsass] 2 feet of her hair,
her prized possession, is taken.
253
00:14:23,530 --> 00:14:26,097
That is what's known as a token.
254
00:14:26,099 --> 00:14:28,933
This adds to the fact that the
person who committed the crime
255
00:14:28,935 --> 00:14:31,469
knew Lisa because
they would have known
256
00:14:31,471 --> 00:14:35,206
that her hair was, really,
a big part of her life.
257
00:14:35,208 --> 00:14:38,776
[Shouldice] It would imply
that there is a fixation
258
00:14:38,778 --> 00:14:43,114
or there is something beyond
just the violence involved.
259
00:14:43,116 --> 00:14:46,117
[Stockdale] The killer
cutting her hair could be a way
260
00:14:46,119 --> 00:14:48,052
of humiliating her.
261
00:14:48,054 --> 00:14:49,587
It could be a way
of sending a message
262
00:14:49,589 --> 00:14:52,857
that I am attacking you, and
I'm attacking your sexuality,
263
00:14:52,859 --> 00:14:54,592
and your femininity.
264
00:14:54,594 --> 00:14:58,363
Maybe I want to take
this to also possess you.
265
00:14:58,365 --> 00:15:01,032
Maybe he wants
a memento or trophy
266
00:15:01,034 --> 00:15:04,469
that he can use
for his own purposes.
267
00:15:04,471 --> 00:15:06,271
[Arntfield] By
removing her hair,
268
00:15:06,273 --> 00:15:09,941
it would have just intensified
the killer's obsessive tendencies.
269
00:15:09,943 --> 00:15:12,043
The need to own her...
270
00:15:12,045 --> 00:15:13,244
even in death.
271
00:15:17,983 --> 00:15:19,817
[narrator] Inspectors
ask Helen Valdez
272
00:15:19,819 --> 00:15:21,819
if there are any men
in Lisa's life
273
00:15:21,821 --> 00:15:26,624
who might match the profile of a
man who was obsessed with her.
274
00:15:26,626 --> 00:15:30,328
Helen said that Lisa had
told her during the dinner party
275
00:15:30,330 --> 00:15:32,030
that she had a date
with somebody new
276
00:15:32,032 --> 00:15:33,865
the following day,
on Sunday, May 17.
277
00:15:33,867 --> 00:15:37,502
Helen did not know who
this individual was.
278
00:15:37,504 --> 00:15:41,706
It became a potentially
interesting lead
279
00:15:41,708 --> 00:15:45,643
because she perhaps had
received a visit from him prematurely
280
00:15:45,645 --> 00:15:47,612
and let him into her apartment.
281
00:15:47,614 --> 00:15:52,583
Trying to find this individual rapidly
became a focus of the investigation.
282
00:15:54,820 --> 00:15:57,088
[narrator] Then results
come in from the analysis
283
00:15:57,090 --> 00:15:59,123
of Lisa's computer and
her telephone
284
00:15:59,125 --> 00:16:04,095
with fresh leads
for inspectors to dig into.
285
00:16:04,097 --> 00:16:07,165
Computer forensics
investigators determined
286
00:16:07,167 --> 00:16:11,235
that at approximately
12:10 a.m. on Sunday, May 17,
287
00:16:11,237 --> 00:16:13,571
Lisa was updating
her own website,
288
00:16:13,573 --> 00:16:18,009
which would have been shortly after
her mother Helen had left around midnight.
289
00:16:18,011 --> 00:16:22,246
Her computer was then abruptly
shut down without logging off
290
00:16:22,248 --> 00:16:24,749
or anything like that
at 1:30 in the morning.
291
00:16:25,651 --> 00:16:27,418
So as we examine the timeline,
292
00:16:27,420 --> 00:16:31,222
given the loud noise
at about 1:26 a.m.,
293
00:16:31,224 --> 00:16:34,058
and then you look
at the improper shutdown
294
00:16:34,060 --> 00:16:37,061
of Lisa's computer
at 1:30 a.m.,
295
00:16:37,063 --> 00:16:39,831
it would suggest
that the dynamics had shifted
296
00:16:39,833 --> 00:16:41,532
within her apartment
at that time.
297
00:16:41,534 --> 00:16:45,003
[Hofsass] The theory is that it
could have been the perpetrator
298
00:16:45,005 --> 00:16:47,772
that either just
shut it down or unplugged it.
299
00:16:49,141 --> 00:16:54,112
The investigation also reveals
that at 2:50 a.m.,
300
00:16:54,114 --> 00:16:57,482
a call comes in to Lisa's
landline which is unanswered.
301
00:16:57,484 --> 00:16:59,183
[phone beeping]
302
00:16:59,185 --> 00:17:03,654
This call is received
by the answering machine.
303
00:17:03,656 --> 00:17:06,657
[narrator] The caller identifies
himself as Kevin Duvall.
304
00:17:06,659 --> 00:17:10,461
[Hofsass] Kevin states,
"Hi, Lisa. Hi, sweetie.
305
00:17:10,463 --> 00:17:13,364
I'm sorry I'm not gonna be
able to make the date today.
306
00:17:13,366 --> 00:17:14,832
Talk to you soon.
Thanks. Bye."
307
00:17:14,834 --> 00:17:19,137
We needed to find Kevin.
308
00:17:19,139 --> 00:17:21,739
[narrator] Then the
investigation gets another boost.
309
00:17:21,741 --> 00:17:26,144
When Lisa's housekeeper comes
forward with new information.
310
00:17:26,146 --> 00:17:29,280
The housekeeper comes every
Monday to clean Lisa's condo.
311
00:17:29,282 --> 00:17:34,585
But on Monday, May 18, at
around 10:00 in the morning,
312
00:17:34,587 --> 00:17:37,155
she gets to Lisa's condo,
opens the door,
313
00:17:37,157 --> 00:17:42,593
and sees Lisa on the floor
and a gym bag on one side
314
00:17:42,595 --> 00:17:46,864
and she hears a male voice and
says, "Oh, I don't want to interrupt.
315
00:17:46,866 --> 00:17:48,566
I'll come back next week."
316
00:17:48,568 --> 00:17:51,302
And she quickly closes the door.
317
00:17:51,304 --> 00:17:55,306
So that led investigators
to think that the perpetrator
318
00:17:55,308 --> 00:17:58,242
stayed in the house
for over 30 hours.
319
00:17:58,244 --> 00:18:05,283
He was there after midnight on
Sunday, May 17, through Monday at 10am.
320
00:18:05,285 --> 00:18:07,585
How scary is that? [chuckles]
321
00:18:07,587 --> 00:18:12,523
That he was able to stay that long
is kind of disturbing and unusual.
322
00:18:12,525 --> 00:18:17,128
We are not sure what he could of
possibly been doing that entire time.
323
00:18:23,669 --> 00:18:25,703
[narrator] In a sadistic
killing of Lisa Valdez,
324
00:18:25,705 --> 00:18:30,208
homicide investigators have learned
that the young woman's murderer
325
00:18:30,210 --> 00:18:34,812
likely stayed with her dead
body for more than 30 hours.
326
00:18:34,814 --> 00:18:38,316
The theory is that
she is murdered on May 17
327
00:18:38,318 --> 00:18:41,419
at almost 1:30,
early hours of Sunday morning.
328
00:18:41,421 --> 00:18:46,424
And, so, thanks to the
housekeeper's account of the timeline,
329
00:18:46,426 --> 00:18:50,294
he still there Monday morning,
May 18, at 10:00.
330
00:18:50,296 --> 00:18:53,331
At this point we are still
struggling to connect the dots
331
00:18:53,333 --> 00:18:55,600
so this just
confounds the investigation
332
00:18:55,602 --> 00:18:59,470
and adds to the complexity
of what's going on.
333
00:19:01,140 --> 00:19:05,076
It merits noting that Lisa's
killer spent over 24 hours
334
00:19:05,078 --> 00:19:06,777
with her body postmortem.
335
00:19:06,779 --> 00:19:08,446
It suggests a number of things.
336
00:19:08,448 --> 00:19:11,916
We know for instance that convicted
sexual sadists and sexual murderers
337
00:19:11,918 --> 00:19:14,719
like to spend prolonged
amounts of time with their victims.
338
00:19:14,721 --> 00:19:18,556
They see their victims as objects to
be possessed and experimented with.
339
00:19:18,558 --> 00:19:22,627
It ups the ante in terms of
how dangerous this person is.
340
00:19:24,730 --> 00:19:27,198
[narrator] Investigators
need to determine
341
00:19:27,200 --> 00:19:29,634
if there is a connection
between the phone message
342
00:19:29,636 --> 00:19:35,540
left for Lisa by Kevin Duvall
at 2:52 a.m. and her murder.
343
00:19:35,542 --> 00:19:40,311
The phone call on her answering
machine is from a payphone.
344
00:19:40,313 --> 00:19:42,914
[Shouldice] The content
of the message was a young man
345
00:19:42,916 --> 00:19:46,250
who had to cancel a date
for later on that afternoon.
346
00:19:46,252 --> 00:19:49,120
Certainly the possibility
would exist
347
00:19:49,122 --> 00:19:53,457
that if this individual
called at that time,
348
00:19:53,459 --> 00:19:57,628
he could, conceivably, be attempting
to create some kind of alibi position
349
00:19:57,630 --> 00:19:59,931
for himself if he was involved.
350
00:20:02,634 --> 00:20:07,772
The fact that Lisa had a date planned with
some mystery man after she was murdered
351
00:20:07,774 --> 00:20:11,742
and that this guy, Kevin, had canceled
that date around 2:00 in the morning,
352
00:20:11,744 --> 00:20:14,345
this in itself is inherently
suspicious.
353
00:20:18,617 --> 00:20:20,985
[narrator] Inspectors
look into Kevin Duvall,
354
00:20:20,987 --> 00:20:24,255
and discover his phone number
in Lisa's address book.
355
00:20:24,257 --> 00:20:27,792
[Hofsass] We were looking for
anyone who had any issues with Lisa,
356
00:20:27,794 --> 00:20:30,228
that maybe was
passionately in love with her
357
00:20:30,230 --> 00:20:31,662
that she didn't accept.
358
00:20:33,031 --> 00:20:35,366
Kevin comes into the station
359
00:20:35,368 --> 00:20:40,271
to provide a statement regarding
the last contact he had with Lisa.
360
00:20:40,273 --> 00:20:43,541
Investigators found that Kevin
Duvall, during their interview,
361
00:20:43,543 --> 00:20:45,610
was behaving very nervously
362
00:20:45,612 --> 00:20:47,411
and that he had
advised the police
363
00:20:47,413 --> 00:20:49,213
that he met Lisa through
a recruiting center
364
00:20:49,215 --> 00:20:51,616
where the two were
looking for work
365
00:20:51,618 --> 00:20:54,819
and that their friendship
then developed and blossomed.
366
00:20:54,821 --> 00:20:56,454
[Hofsass]
In Kevin's statement,
367
00:20:56,456 --> 00:21:00,458
he mentioned that the reason he
canceled the date with Lisa on that Sunday
368
00:21:00,460 --> 00:21:04,362
was wasn't feeling well and he just wanted
to give her a heads-up and let her know
369
00:21:04,364 --> 00:21:08,366
in the middle of the night
that that was the case.
370
00:21:08,368 --> 00:21:11,269
[narrator] As detectives
continued to question Kevin
371
00:21:11,271 --> 00:21:13,838
they observe
something suspicious.
372
00:21:13,840 --> 00:21:15,806
[Arntfield] Police note
that on Kevin's hand,
373
00:21:15,808 --> 00:21:19,510
he has this laceration
that is consistent
374
00:21:19,512 --> 00:21:22,113
with the types of wounds
obtained unintentionally
375
00:21:22,115 --> 00:21:25,283
by offenders who stab a victim.
376
00:21:25,285 --> 00:21:29,120
It's very difficult to repeatedly
stab someone with most knives
377
00:21:29,122 --> 00:21:32,456
and not sustain some kind
of incidental self-injury.
378
00:21:32,458 --> 00:21:36,694
This immediately is
going to raise some red flags.
379
00:21:36,696 --> 00:21:39,196
The cut could indicate
that he was the perpetrator
380
00:21:39,198 --> 00:21:43,834
because we know that blood was
dripped onto the pillow after the stabbing.
381
00:21:46,138 --> 00:21:48,773
[narrator] When inspectors
ask about his whereabouts
382
00:21:48,775 --> 00:21:51,909
in the early hours
of Sunday, May 17,
383
00:21:51,911 --> 00:21:54,378
Kevin's alibi is that
he was home alone.
384
00:21:56,048 --> 00:21:59,116
When you are alone, you have no
one to witness that you are alone.
385
00:21:59,118 --> 00:22:03,054
This was before GPS
and surveillance cameras
386
00:22:03,056 --> 00:22:07,291
and so, there was nobody who could
substantiate his being home alone.
387
00:22:08,960 --> 00:22:13,264
Kevin becomes the prime suspect
because there is no real alibi
388
00:22:13,266 --> 00:22:15,032
and he did have
a cut on his hand.
389
00:22:15,034 --> 00:22:17,802
We're thinking, "if he has a cut
on his hand, he must be the killer."
390
00:22:19,905 --> 00:22:24,075
We requested that he provide
DNA samples and fingerprints.
391
00:22:24,077 --> 00:22:27,878
[Hofsass] Along with his
DNA swabs and fingerprints,
392
00:22:27,880 --> 00:22:31,449
Kevin agrees to take
a polygraph exam.
393
00:22:31,451 --> 00:22:33,751
His polygraph was inconclusive,
394
00:22:33,753 --> 00:22:36,887
which means that they
couldn't say without a doubt
395
00:22:36,889 --> 00:22:38,322
that he was telling
the whole truth.
396
00:22:39,891 --> 00:22:42,593
[narrator] But when
the forensic results come in,
397
00:22:42,595 --> 00:22:45,262
they are conclusive.
398
00:22:45,264 --> 00:22:47,665
The results eliminate him
and exclude him
399
00:22:47,667 --> 00:22:49,500
as a source of the blood
on the pillow,
400
00:22:49,502 --> 00:22:53,137
fingerprint-wise and DNA-wise.
401
00:22:53,139 --> 00:22:56,841
So Kevin could not
have been the killer.
402
00:22:56,843 --> 00:22:59,577
[narrator] With their prime
suspect eliminated,
403
00:22:59,579 --> 00:23:02,446
investigators are
still left with the DNA
404
00:23:02,448 --> 00:23:05,349
of an unknown male killer,
and not much else.
405
00:23:07,486 --> 00:23:09,019
Lisa knows her killer,
406
00:23:09,021 --> 00:23:12,590
and this is probably someone
who has obsessed over her.
407
00:23:12,592 --> 00:23:14,592
Maybe he's been rejected
408
00:23:14,594 --> 00:23:17,328
and he moves from rejected
to resentful.
409
00:23:17,330 --> 00:23:22,633
The more he ruminates on this, the
more potentially his violence increases,
410
00:23:22,635 --> 00:23:24,969
so this obsession turns deadly.
411
00:23:25,804 --> 00:23:27,338
This guy is really a cornucopia
412
00:23:27,340 --> 00:23:30,908
of high-risk
sexual preoccupations.
413
00:23:30,910 --> 00:23:35,413
All of which points to a
disordered but obsessive mind.
414
00:23:38,049 --> 00:23:41,152
[Hofsass] Officers interview,
like, 50 people at least.
415
00:23:41,154 --> 00:23:43,120
Every person that
they've interviewed,
416
00:23:43,122 --> 00:23:46,657
every person that they've
sampled is hitting a deadend,
417
00:23:46,659 --> 00:23:49,260
and that's very frustrating.
418
00:23:49,262 --> 00:23:52,062
[narrator] Inspectors circle
back to Lisa's mother, Helen,
419
00:23:52,064 --> 00:23:53,964
to see if there's anyone else
420
00:23:53,966 --> 00:23:57,735
who comes to mind who fits
the profile of the killer.
421
00:23:57,737 --> 00:24:00,738
We came across
one potential suspect.
422
00:24:00,740 --> 00:24:04,308
Gary, who they were
very interested in.
423
00:24:04,310 --> 00:24:05,876
[Hofsass]
According to Lisa's friends,
424
00:24:05,878 --> 00:24:09,046
they dated in the past,
maybe one or two dates.
425
00:24:09,048 --> 00:24:12,016
He was very much into her
and she was not into him,
426
00:24:12,018 --> 00:24:14,318
and so that piqued the interest
427
00:24:14,320 --> 00:24:15,786
for the investigation,
428
00:24:15,788 --> 00:24:18,889
'cause now we are talking
about unrequited love
429
00:24:18,891 --> 00:24:21,859
and possible jealousy.
430
00:24:21,861 --> 00:24:23,561
[narrator] Helen Valdez
hadn't thought much
431
00:24:23,563 --> 00:24:26,063
of Gary Walker
before the murder.
432
00:24:26,065 --> 00:24:28,699
But recent events have raised
her suspicion.
433
00:24:30,168 --> 00:24:33,337
There was a memorial
service for Lisa.
434
00:24:33,339 --> 00:24:36,841
And Gary read a letter
out loud to everyone,
435
00:24:36,843 --> 00:24:39,844
that was very unusual and scary,
436
00:24:39,846 --> 00:24:41,879
I guess, is the right word.
437
00:24:41,881 --> 00:24:45,749
The letter that he read at
the memorial service stated,
438
00:24:45,751 --> 00:24:47,585
"If I killed Lisa..."
439
00:24:47,587 --> 00:24:50,421
It also stated he would have
never done that
440
00:24:50,423 --> 00:24:52,756
because he loved her so much.
441
00:24:52,758 --> 00:24:56,160
It was really bizarre
and very, very strange.
442
00:24:56,162 --> 00:24:58,295
People were surprised
and taken aback.
443
00:24:59,831 --> 00:25:01,966
[Arntfield] Gary's disturbing
poem reading...
444
00:25:01,968 --> 00:25:03,634
I mean, this is someone who is
445
00:25:03,636 --> 00:25:05,636
a little too preoccupied
with Lisa.
446
00:25:05,638 --> 00:25:09,740
This to me speaks of
a certain degree of obsession,
447
00:25:09,742 --> 00:25:11,609
even of obsessive fantasy.
448
00:25:12,911 --> 00:25:15,112
[Hofsass] He literally becomes
the prime suspect
449
00:25:15,114 --> 00:25:16,447
with that information.
450
00:25:17,349 --> 00:25:18,649
[Lisa screams]
451
00:25:20,919 --> 00:25:22,152
[narrator]
In the gruesome murder
452
00:25:22,154 --> 00:25:24,388
of 36-year-old Lisa Valdez,
453
00:25:24,390 --> 00:25:27,324
inspectors are zeroing in
on a new suspect,
454
00:25:27,326 --> 00:25:28,893
Gary Walker.
455
00:25:28,895 --> 00:25:30,561
A man she once dated
456
00:25:30,563 --> 00:25:33,831
who developed a twisted
obsession with her.
457
00:25:33,833 --> 00:25:37,067
This prime suspect is
infatuated with Lisa.
458
00:25:38,069 --> 00:25:40,137
When you tie that in
with the letter
459
00:25:40,139 --> 00:25:42,406
that he read
at the memorial service
460
00:25:42,408 --> 00:25:44,808
that stated, "If I killed Lisa,"
461
00:25:44,810 --> 00:25:48,078
we have bizarre
behavior from this individual.
462
00:25:48,080 --> 00:25:50,247
She definitely
was not interested,
463
00:25:50,249 --> 00:25:51,749
and so he murdered her.
464
00:25:51,751 --> 00:25:53,884
That's the theory, right?
465
00:25:53,886 --> 00:25:57,788
And it's quite possible
that's why she's dead.
466
00:25:57,790 --> 00:26:00,824
[narrator] With suspicions
swirling around Gary Walker,
467
00:26:00,826 --> 00:26:04,094
detectives haul him into
the station for questioning.
468
00:26:04,096 --> 00:26:06,564
Gary says
he's very close to Lisa,
469
00:26:06,566 --> 00:26:08,566
he's a good friend of hers,
470
00:26:08,568 --> 00:26:12,069
and that he considered
Lisa his soulmate.
471
00:26:12,071 --> 00:26:16,473
He would never do any
kind of harm to her at all.
472
00:26:16,475 --> 00:26:19,076
[narrator] Investigators
drill down on Gary's timeline
473
00:26:19,078 --> 00:26:21,612
in the hours leading up
to Lisa's murder.
474
00:26:23,348 --> 00:26:24,949
So, according to
Gary's statement,
475
00:26:24,951 --> 00:26:29,386
he was with friends on the
evening of May 16th, Saturday.
476
00:26:29,388 --> 00:26:32,456
And then after midnight
on Sunday morning,
477
00:26:32,458 --> 00:26:36,493
he was at home asleep
alone in his apartment.
478
00:26:36,495 --> 00:26:38,095
But there was nobody who could
479
00:26:38,097 --> 00:26:41,432
substantiate his being
home alone and asleep
480
00:26:41,434 --> 00:26:44,735
and not having anything to do
with this murder at the time.
481
00:26:46,237 --> 00:26:49,173
A DNA swab
is collected from Gary
482
00:26:49,175 --> 00:26:52,610
and fingerprints are collected
so that we can compare it
483
00:26:52,612 --> 00:26:55,946
to the latent fingerprints
from the toilet seat
484
00:26:55,948 --> 00:26:58,515
and the DNA evidence
from the pillow
485
00:26:58,517 --> 00:27:00,818
that we have
from the crime scene.
486
00:27:00,820 --> 00:27:03,821
[narrator] Investigators also
obtain search warrants
487
00:27:03,823 --> 00:27:05,556
for Gary's home and vehicle.
488
00:27:06,524 --> 00:27:08,158
He is the prime suspect.
489
00:27:08,160 --> 00:27:10,027
And when they search
Gary's house,
490
00:27:10,029 --> 00:27:13,697
they find evidence
of his infatuation with Lisa.
491
00:27:13,699 --> 00:27:18,869
There's pictures and letters
and mementos of Lisa all over.
492
00:27:18,871 --> 00:27:20,838
When police
search his residence,
493
00:27:20,840 --> 00:27:23,841
they find a shrine to Lisa.
494
00:27:23,843 --> 00:27:25,175
Photographs.
495
00:27:25,177 --> 00:27:27,711
Photographs intermingled
with pornography,
496
00:27:27,713 --> 00:27:30,648
and essentially all things Lisa
497
00:27:30,650 --> 00:27:33,417
that suggest Gary
was beyond obsessed.
498
00:27:35,887 --> 00:27:37,287
The homicide inspectors
499
00:27:37,289 --> 00:27:40,391
felt that he may be
indeed her murderer.
500
00:27:44,195 --> 00:27:47,398
[narrator] Police sees plenty
of incriminating evidence,
501
00:27:47,400 --> 00:27:49,433
but while all of it plays
to the profile
502
00:27:49,435 --> 00:27:51,335
of an obsessed killer,
503
00:27:51,337 --> 00:27:54,705
nothing from Gary's home
comes back with Lisa's DNA.
504
00:27:56,274 --> 00:27:58,008
Nothing had blood drips on it.
505
00:27:58,010 --> 00:28:01,545
There was no evidence that he
took something from the scene
506
00:28:01,547 --> 00:28:03,080
and brought it back
to his house.
507
00:28:03,082 --> 00:28:04,281
There was no evidence
508
00:28:04,283 --> 00:28:06,684
that we could tie it
to the crime scene.
509
00:28:06,686 --> 00:28:10,621
So there's no proof that
he committed the crime.
510
00:28:12,323 --> 00:28:15,559
[narrator] But with no one
able to verify Gary's alibi,
511
00:28:15,561 --> 00:28:19,096
inspectors ask him to submit
to a polygraph test.
512
00:28:20,398 --> 00:28:22,900
They definitely thought he was
going to fail the polygraph
513
00:28:22,902 --> 00:28:24,768
and confess to the murder.
514
00:28:24,770 --> 00:28:28,772
That was their hope, and
it didn't pan out that way.
515
00:28:28,774 --> 00:28:31,942
They subject Gary
to a couple of polygraphs.
516
00:28:31,944 --> 00:28:34,178
They come back inconclusive
517
00:28:34,180 --> 00:28:35,813
each and every time.
518
00:28:36,781 --> 00:28:38,348
[narrator] The only
remaining avenue
519
00:28:38,350 --> 00:28:41,585
of investigation into Gary
is the forensics.
520
00:28:41,587 --> 00:28:43,654
[Hofsass] The fingerprints
eliminate Gary
521
00:28:43,656 --> 00:28:44,955
from the crime scene,
522
00:28:44,957 --> 00:28:47,925
and so then it's a matter
of getting the DNA results in.
523
00:28:47,927 --> 00:28:52,029
And the DNA is also excluding
Gary from the crime scene.
524
00:28:52,864 --> 00:28:55,566
It could have been
the breakthrough,
525
00:28:55,568 --> 00:28:56,467
and it wasn't.
526
00:28:57,168 --> 00:28:58,502
We're still at a deadend.
527
00:28:58,504 --> 00:29:00,671
We don't have
any other information
528
00:29:00,673 --> 00:29:02,506
about who committed this crime.
529
00:29:04,375 --> 00:29:07,344
The investigation
essentially hits the wall.
530
00:29:09,114 --> 00:29:11,081
[narrator] Over the course
of several months,
531
00:29:11,083 --> 00:29:15,486
investigators obtain and test
the DNA of dozens of other men
532
00:29:15,488 --> 00:29:19,089
in Lisa's address book
and list of caller IDs.
533
00:29:19,091 --> 00:29:21,792
We were still receiving
from the homicide inspectors
534
00:29:21,794 --> 00:29:24,795
a series of potential candidates
535
00:29:24,797 --> 00:29:26,997
for comparison
against the fingerprints
536
00:29:26,999 --> 00:29:29,233
collected from the crime scene.
537
00:29:29,235 --> 00:29:32,636
At least a dozen sets of
prints were admitted to CSI
538
00:29:32,638 --> 00:29:34,605
for comparison against that,
539
00:29:34,607 --> 00:29:37,007
and every one of them
was negative.
540
00:29:37,842 --> 00:29:39,443
[Hofsass]
We've already eliminated
541
00:29:39,445 --> 00:29:42,980
so many of the contacts
through interviewing and testing,
542
00:29:42,982 --> 00:29:45,716
also contacting people
she has dated,
543
00:29:45,718 --> 00:29:49,219
or her ex-boyfriends,
and everybody is eliminated.
544
00:29:49,221 --> 00:29:53,056
There's no evidence of who
might have committed the crime.
545
00:29:55,026 --> 00:29:56,627
[narrator]
Months turn to years
546
00:29:56,629 --> 00:29:58,295
and the case grows cold
547
00:29:58,297 --> 00:30:01,598
and stays cold for
more than a decade.
548
00:30:01,600 --> 00:30:05,102
The thing that stuck out
for me was that this gal,
549
00:30:05,104 --> 00:30:07,638
she lived on her own,
she was self-sufficient,
550
00:30:07,640 --> 00:30:09,072
she was independent.
551
00:30:09,074 --> 00:30:10,407
She loved life.
552
00:30:10,409 --> 00:30:13,911
I related to a lot of that,
and so I saw myself in her.
553
00:30:13,913 --> 00:30:16,814
And I saw the way she was
brutally murdered.
554
00:30:16,816 --> 00:30:20,984
I actually had the DNA
profile in a chart on my desk,
555
00:30:20,986 --> 00:30:24,354
and every time a case came up
and we had a reference sample
556
00:30:24,356 --> 00:30:26,390
come in for a violent crime,
557
00:30:26,392 --> 00:30:29,993
I would look at that profile
to see if there was a match.
558
00:30:29,995 --> 00:30:32,863
And year after year,
I would call the state lab
559
00:30:32,865 --> 00:30:36,466
and just ask them to conduct
a quick search of that profile
560
00:30:36,468 --> 00:30:38,936
that's already in CODIS
and still not a match.
561
00:30:39,804 --> 00:30:41,672
[Shouldice]
I left that fingerprint
562
00:30:41,674 --> 00:30:43,173
from the crime scene on my desk
563
00:30:43,175 --> 00:30:45,209
where it remained for years.
564
00:30:45,211 --> 00:30:46,410
It was a constant reminder
565
00:30:46,412 --> 00:30:49,079
that there was still
an unidentified fingerprint
566
00:30:49,081 --> 00:30:51,682
within that case file.
567
00:30:51,684 --> 00:30:52,983
[Arntfield] Lisa's murder
is a case that,
568
00:30:52,985 --> 00:30:55,853
beginning to end,
lends itself to obsession.
569
00:30:55,855 --> 00:30:59,323
We have the very malicious
obsession of the killer
570
00:30:59,325 --> 00:31:01,592
and some other people
in her life,
571
00:31:01,594 --> 00:31:04,328
but then we have
the very benevolent
572
00:31:04,330 --> 00:31:06,964
and virtuous obsession
of the police
573
00:31:06,966 --> 00:31:08,999
who will never let this case go.
574
00:31:10,168 --> 00:31:12,236
[narrator] Then, Pam Hofsass
attends a conference
575
00:31:12,238 --> 00:31:14,071
for homicide detectives,
576
00:31:14,073 --> 00:31:17,374
where she learns
how popular familial DNA sites
577
00:31:17,376 --> 00:31:19,643
can be used to solve crimes.
578
00:31:19,645 --> 00:31:22,813
Instead of looking for
an exact perfect DNA match,
579
00:31:22,815 --> 00:31:25,349
we look for a partial match.
580
00:31:25,351 --> 00:31:27,484
In other words,
if there is a relative,
581
00:31:27,486 --> 00:31:29,753
like a brother, a son,
582
00:31:29,755 --> 00:31:32,189
or father, biologically,
583
00:31:32,191 --> 00:31:34,224
they are going
to have very similar
584
00:31:34,226 --> 00:31:37,361
genetic information
as a DNA profile,
585
00:31:37,363 --> 00:31:39,930
and if they would be
in the database,
586
00:31:39,932 --> 00:31:42,566
then we could backtrack
and do research
587
00:31:42,568 --> 00:31:44,334
on the backend to see
588
00:31:44,336 --> 00:31:48,238
if any of those relatives
were in the area or available,
589
00:31:48,240 --> 00:31:50,741
let's say, to commit that crime.
590
00:31:50,743 --> 00:31:53,977
When I got back, I told
my lieutenant at the time,
591
00:31:53,979 --> 00:31:56,480
"We got to do a familial
search on Lisa Valdez."
592
00:31:56,482 --> 00:31:59,049
[narrator] Investigators
hope the killer's DNA
593
00:31:59,051 --> 00:32:00,784
they found on the pillow case
594
00:32:00,786 --> 00:32:03,320
can be matched to
one of their family members.
595
00:32:03,322 --> 00:32:07,891
But on September 2nd, 2011,
Inspector Hofsass gains
596
00:32:07,893 --> 00:32:11,662
new information that breaks
the case wide open.
597
00:32:11,664 --> 00:32:13,297
[Hofsass] I got a call
from the state lab,
598
00:32:13,299 --> 00:32:15,232
and they said, "We always do
599
00:32:15,234 --> 00:32:18,035
one last CODIS search
before we do a familial."
600
00:32:18,037 --> 00:32:20,237
And they said we did
one last search
601
00:32:20,239 --> 00:32:24,141
and your guy was just arrested
and finally sampled for DNA
602
00:32:24,143 --> 00:32:26,743
and entered into
the DNA database.
603
00:32:26,745 --> 00:32:28,245
We have a perfect match.
604
00:32:29,514 --> 00:32:31,415
Finally, this is the guy.
605
00:32:33,484 --> 00:32:35,552
[narrator] The previously
unidentified male
606
00:32:35,554 --> 00:32:37,888
who left his DNA
at the crime scene
607
00:32:37,890 --> 00:32:40,157
has been recently
arrested in San Francisco
608
00:32:40,159 --> 00:32:42,125
on a shoplifting charge.
609
00:32:42,127 --> 00:32:45,796
His name is
Anthony Quinn Hughes.
610
00:32:45,798 --> 00:32:46,997
[Lisa yelps]
611
00:32:46,999 --> 00:32:49,299
[Hofsass] Anthony Quinn Hughes
had never come up
612
00:32:49,301 --> 00:32:51,268
in the course of
the original investigation,
613
00:32:51,270 --> 00:32:54,004
and he was not on the radar.
614
00:32:54,006 --> 00:32:56,506
Now, this individual
was arrested
615
00:32:56,508 --> 00:33:00,510
and he was finally swabbed
as a felony arrest
616
00:33:00,512 --> 00:33:03,180
and that's how it connected
to the unknown DNA profile
617
00:33:03,182 --> 00:33:07,684
that was hovering and waiting
for someone to finally match.
618
00:33:07,686 --> 00:33:11,054
Thirteen years since
the homicide of Lisa Valdez,
619
00:33:11,056 --> 00:33:13,123
and it was just
an amazing feeling.
620
00:33:13,125 --> 00:33:16,226
I couldn't wait to figure out
where this guy was,
621
00:33:16,228 --> 00:33:19,196
and get him in custody
for Lisa's murder.
622
00:33:22,934 --> 00:33:24,735
[narrator] Thirteen years
after the murder
623
00:33:24,737 --> 00:33:28,238
of Lisa Valdez,
police match her killer's DNA
624
00:33:28,240 --> 00:33:31,274
from the scene to a man
named Anthony Quinn Hughes,
625
00:33:31,276 --> 00:33:32,609
caught shoplifting
626
00:33:32,611 --> 00:33:35,045
in San Francisco's
Tenderloin neighborhood.
627
00:33:36,581 --> 00:33:41,485
At that time, I'm contacted
by Inspector Pam Hofsass
628
00:33:41,487 --> 00:33:43,587
in a state of great excitement.
629
00:33:43,589 --> 00:33:46,189
And I think her opening line
may have been,
630
00:33:46,191 --> 00:33:48,191
"You won't believe it."
631
00:33:48,193 --> 00:33:52,662
Now, Anthony Hughes actually
had fingerprints on file
632
00:33:52,664 --> 00:33:54,531
and she wanted me to compare
633
00:33:54,533 --> 00:33:56,666
the fingerprint
from the toilet seat
634
00:33:56,668 --> 00:33:58,135
against this set of prints.
635
00:33:59,170 --> 00:34:01,438
I did that,
and later the same day,
636
00:34:01,440 --> 00:34:05,342
I was able to return the
compliment by telling her it's him.
637
00:34:06,377 --> 00:34:08,345
I felt like celebrating,
frankly.
638
00:34:08,347 --> 00:34:10,447
It was a big day.
639
00:34:10,449 --> 00:34:13,750
[narrator] Now 52-years-old,
Anthony Hughes would have
640
00:34:13,752 --> 00:34:17,120
been in his late 30s
at the time of Lisa's murder.
641
00:34:17,122 --> 00:34:19,623
Investigators
returned to the case files
642
00:34:19,625 --> 00:34:22,025
looking for
a connection to Lisa.
643
00:34:23,561 --> 00:34:27,431
His name never came up
in any of the conversations
644
00:34:27,433 --> 00:34:29,466
with friends of Lisa
or the family.
645
00:34:29,468 --> 00:34:33,136
But further review
of the original case files
646
00:34:33,138 --> 00:34:35,739
show that he was
in her address book
647
00:34:35,741 --> 00:34:39,109
and he was
on her answering machine.
648
00:34:39,111 --> 00:34:41,745
[narrator] With DNA
and fingerprint matches,
649
00:34:41,747 --> 00:34:43,880
inspectors obtain
an arrest warrant
650
00:34:43,882 --> 00:34:45,582
for Anthony Quinn Hughes.
651
00:34:47,251 --> 00:34:49,820
The challenge for us
was to try to locate him,
652
00:34:49,822 --> 00:34:51,555
since he didn't
have any known address
653
00:34:51,557 --> 00:34:53,523
through our database records.
654
00:34:53,525 --> 00:34:56,326
We just knew where
he was arrested most recently.
655
00:34:56,328 --> 00:35:00,097
The idea was that he had
to be from that area.
656
00:35:00,099 --> 00:35:04,167
Within 24 hours
of that warrant being issued,
657
00:35:04,169 --> 00:35:05,735
Mr. Hughes jaywalked
658
00:35:05,737 --> 00:35:09,339
in front of a police car
and was recognized
659
00:35:09,341 --> 00:35:10,874
and was taken into custody.
660
00:35:12,743 --> 00:35:14,177
[narrator]
Anthony is questioned
661
00:35:14,179 --> 00:35:16,546
at San Francisco's
police headquarters.
662
00:35:17,548 --> 00:35:19,649
[Hofsass] He was
just kind of disheveled
663
00:35:19,651 --> 00:35:21,718
and appeared homeless,
664
00:35:21,720 --> 00:35:26,189
but he's very friendly
and outgoing.
665
00:35:26,191 --> 00:35:27,724
[narrator]
Inspectors show Anthony
666
00:35:27,726 --> 00:35:30,927
a photograph of Lisa Valdez.
667
00:35:30,929 --> 00:35:33,430
[Hofsass] When we first
showed him the photo of Lisa,
668
00:35:33,432 --> 00:35:35,732
he says he doesn't know her.
669
00:35:35,734 --> 00:35:39,002
Slowly but surely, through the
course of the interrogation,
670
00:35:39,004 --> 00:35:42,105
he admitted that he knew
Lisa from high school,
671
00:35:42,107 --> 00:35:44,207
that they dated
for a little bit.
672
00:35:44,209 --> 00:35:46,443
He was 17 and she was 16.
673
00:35:46,445 --> 00:35:50,147
He definitely felt like Lisa's
mom did not approve of him,
674
00:35:50,149 --> 00:35:51,615
and then he moved on
675
00:35:51,617 --> 00:35:53,884
and got married
and had children,
676
00:35:53,886 --> 00:35:56,119
and that kind of thing.
677
00:35:56,121 --> 00:35:59,122
And then I said, "When's the
last time you had contact with her?"
678
00:35:59,124 --> 00:36:02,058
He said something like
the late '80s.
679
00:36:02,060 --> 00:36:04,427
And he talked about how
he had met her jogging
680
00:36:04,429 --> 00:36:07,631
around Lake Merritt in Oakland
which is across the bay.
681
00:36:07,633 --> 00:36:09,065
And we know
she was going to school
682
00:36:09,067 --> 00:36:10,734
at the college right there.
683
00:36:10,736 --> 00:36:12,469
So that was plausible.
684
00:36:12,471 --> 00:36:15,772
And then he talked about
how he hadn't seen her
685
00:36:15,774 --> 00:36:18,708
since then,
which we knew was not true.
686
00:36:18,710 --> 00:36:22,245
The late '90s,
he was in Lisa's address book.
687
00:36:22,247 --> 00:36:26,449
His name, his address,
his phone number, et cetera.
688
00:36:26,451 --> 00:36:27,984
[narrator]
Inspectors press Anthony
689
00:36:27,986 --> 00:36:29,686
for details about what happened
690
00:36:29,688 --> 00:36:31,521
the last time he saw Lisa.
691
00:36:32,290 --> 00:36:34,758
[Hofsass]
He wasn't forthcoming,
692
00:36:34,760 --> 00:36:37,727
but he said he bumped
into her in Oakland.
693
00:36:37,729 --> 00:36:41,998
He said she took him to
her dorm room and, you know,
694
00:36:42,000 --> 00:36:44,267
made some off-the-cuff
comment about
695
00:36:44,269 --> 00:36:46,503
how many guys she slept with
back in that day.
696
00:36:47,905 --> 00:36:50,440
His whole demeanor
just got really angry
697
00:36:50,442 --> 00:36:52,976
and worked up
and he kept saying,
698
00:36:52,978 --> 00:36:55,979
"I don't understand why she
would do that," on and on and on.
699
00:36:55,981 --> 00:36:57,981
It was really
kind of eye-popping.
700
00:36:58,716 --> 00:37:00,317
When Anthony says this,
701
00:37:00,319 --> 00:37:02,886
I don't think
he necessarily realizes
702
00:37:02,888 --> 00:37:05,455
how that comment about
how many partners Lisa has
703
00:37:05,457 --> 00:37:08,458
is so unusual,
and why it would be unusual
704
00:37:08,460 --> 00:37:11,828
that this is something that he's
fantasizing and thinking about.
705
00:37:11,830 --> 00:37:14,030
And so it's been all-consuming.
706
00:37:14,032 --> 00:37:17,300
It's leaking out even in the
course of this questioning.
707
00:37:19,470 --> 00:37:21,671
[narrator] Detectives then
confront Anthony Hughes
708
00:37:21,673 --> 00:37:24,007
with the fact they found his DNA
709
00:37:24,009 --> 00:37:26,042
at the scene of Lisa's murder.
710
00:37:26,044 --> 00:37:28,011
[Hofsass] He denied
being in her condo.
711
00:37:29,313 --> 00:37:31,648
So we asked him
how do you explain your DNA
712
00:37:31,650 --> 00:37:33,049
and your fingerprints there,
713
00:37:33,051 --> 00:37:35,385
and he could not provide
an explanation at all.
714
00:37:37,488 --> 00:37:39,155
He said, "I want to die."
715
00:37:39,157 --> 00:37:41,524
Repeatedly. "I want to die."
716
00:37:41,526 --> 00:37:44,461
And then he did
something pretty spectacular.
717
00:37:44,463 --> 00:37:46,263
My partner and I were looking
at each other like,
718
00:37:46,265 --> 00:37:48,064
"Okay, so now
he's going to confess."
719
00:37:48,066 --> 00:37:51,534
But he took the pen
and he started to write out
720
00:37:51,536 --> 00:37:53,536
what we assumed was
going to be a confession,
721
00:37:53,538 --> 00:37:55,272
instead he took the pen
722
00:37:55,274 --> 00:37:57,207
and started to stab himself.
723
00:37:57,209 --> 00:37:58,241
Oh, no, no, no.
724
00:37:58,243 --> 00:38:00,677
- Don't do that. Don't do that.
- Don't do that.
725
00:38:00,679 --> 00:38:03,647
[Hofsass] Which is a form
of admission, in a sense.
726
00:38:05,716 --> 00:38:07,517
[narrator] After 13 years,
727
00:38:07,519 --> 00:38:10,186
inspectors are finally able
to piece together
728
00:38:10,188 --> 00:38:13,423
the final 24 hours
of Lisa Valdez's life.
729
00:38:13,425 --> 00:38:15,492
[Lisa screaming]
730
00:38:15,494 --> 00:38:17,460
[Hofsass] Lisa and Anthony
731
00:38:17,462 --> 00:38:20,330
had some form of relationship
back in the day,
732
00:38:20,332 --> 00:38:23,333
and years later,
somehow reconnected.
733
00:38:23,335 --> 00:38:27,337
He was upset that she had
boyfriends, and it seemed like
734
00:38:27,339 --> 00:38:32,342
he had some kind of jealousy
and infatuation with Lisa.
735
00:38:32,344 --> 00:38:36,079
He was so besotted with her,
and he was rejected.
736
00:38:37,415 --> 00:38:38,548
[narrator]
In the early morning
737
00:38:38,550 --> 00:38:42,285
- of Sunday, May 17th, 1998...
- [doorbell buzzes]
738
00:38:42,287 --> 00:38:44,487
Anthony finally
decides to visit Lisa
739
00:38:44,489 --> 00:38:46,990
and confess his feelings.
740
00:38:46,992 --> 00:38:49,092
[Hofsass] It appears
that Anthony made contact
741
00:38:49,094 --> 00:38:53,096
at Lisa's condo complex
sometime after midnight.
742
00:38:53,098 --> 00:38:56,299
And he had to have been
buzzed in by Lisa.
743
00:38:56,301 --> 00:38:58,435
[narrator] Some type of
confrontation erupts
744
00:38:58,437 --> 00:39:00,136
between the two of them.
745
00:39:01,172 --> 00:39:04,341
He was somebody
who was fixated on her,
746
00:39:04,343 --> 00:39:06,676
who didn't take no
for an answer,
747
00:39:06,678 --> 00:39:10,146
who was rebuffed
and reacted with a rage,
748
00:39:10,148 --> 00:39:13,450
and it starts to unravel
pretty quickly.
749
00:39:13,452 --> 00:39:15,485
We can assume Anthony
takes a knife
750
00:39:15,487 --> 00:39:17,320
and stabs her repeatedly.
751
00:39:17,322 --> 00:39:19,122
[Shouldice] The fact
that her underwear
752
00:39:19,124 --> 00:39:21,791
had been torn away
suggested strongly
753
00:39:21,793 --> 00:39:25,662
that there was a sexual
element to this homicide.
754
00:39:25,664 --> 00:39:27,530
[Hofsass] So she's
struggling with him,
755
00:39:27,532 --> 00:39:29,833
trying to get him
to stop stabbing her.
756
00:39:29,835 --> 00:39:33,837
At around 1:26 in the morning
when the downstairs neighbors
757
00:39:33,839 --> 00:39:36,339
heard a commotion,
and then she's murdered.
758
00:39:39,443 --> 00:39:41,544
It was a rage killing.
759
00:39:42,513 --> 00:39:44,581
[narrator]
After Anthony kills Lisa,
760
00:39:44,583 --> 00:39:47,917
he stays with her body
for up to 30 hours.
761
00:39:47,919 --> 00:39:50,487
[Hofsass] At some point,
he takes a token of hair.
762
00:39:50,489 --> 00:39:54,124
He cuts her hair at least
two feet, and at some point,
763
00:39:54,126 --> 00:39:56,192
he cleaned up in the bathroom,
764
00:39:56,194 --> 00:39:59,129
and I would assume
that once the housekeeper
765
00:39:59,131 --> 00:40:01,598
came by on Monday, May 18th,
766
00:40:01,600 --> 00:40:03,299
at around 10:00
in the morning,
767
00:40:03,301 --> 00:40:05,001
he might have thought
that police would be coming
768
00:40:05,003 --> 00:40:07,470
right after,
and he hightailed it.
769
00:40:07,472 --> 00:40:10,407
It's possible that Anthony
was a sexual sadist,
770
00:40:10,409 --> 00:40:13,309
given the amount of time
that was reported
771
00:40:13,311 --> 00:40:15,779
that he spent with Lisa's body,
772
00:40:15,781 --> 00:40:18,882
and that he has stabbed her
numerous times.
773
00:40:20,885 --> 00:40:22,685
And he's taken her hair.
774
00:40:22,687 --> 00:40:25,822
He's asserting
his dominance over her.
775
00:40:25,824 --> 00:40:28,091
Maybe in some ways,
this could almost be
776
00:40:28,093 --> 00:40:30,593
a revenge, or vengeful fantasy,
777
00:40:30,595 --> 00:40:32,762
where he's actively
been fantasizing
778
00:40:32,764 --> 00:40:36,499
about committing this
aggressive act towards Lisa.
779
00:40:38,669 --> 00:40:41,337
[narrator] In the heinous
killing of Lisa Valdez,
780
00:40:41,339 --> 00:40:43,673
Anthony Quinn Hughes
is found guilty
781
00:40:43,675 --> 00:40:44,674
of second-degree murder
782
00:40:44,676 --> 00:40:47,377
and is sentenced
to 16 years to life.
783
00:40:48,379 --> 00:40:50,547
There may still be a few
unanswered questions
784
00:40:50,549 --> 00:40:52,449
as to the root of why.
785
00:40:53,551 --> 00:40:55,919
But the combined behaviors,
786
00:40:55,921 --> 00:40:59,289
timelines, and evidence,
when put together,
787
00:40:59,291 --> 00:41:00,723
leaves you at a place
788
00:41:00,725 --> 00:41:02,759
where there's no other
conclusion you can come to.
789
00:41:02,761 --> 00:41:04,828
And that was Anthony Hughes
790
00:41:04,830 --> 00:41:07,297
- is responsible for the murder of Lisa Valdez.
- [doorbell buzzes]
791
00:41:09,400 --> 00:41:11,668
That was a really
satisfying moment
792
00:41:11,670 --> 00:41:13,803
for all of us
and for her family.
793
00:41:13,805 --> 00:41:15,738
That's all you can hope for.
794
00:41:15,740 --> 00:41:17,707
Some glimmer of relief.
795
00:41:17,709 --> 00:41:19,375
That's why you do this job.
796
00:41:19,377 --> 00:41:20,910
To just give families
797
00:41:20,912 --> 00:41:24,914
some measure of closure
and finality.
798
00:41:24,916 --> 00:41:26,483
[Arntfield] Lisa's case,
at the end of the day,
799
00:41:26,485 --> 00:41:28,151
wad solved through a combination
800
00:41:28,153 --> 00:41:31,354
of just dogged, shoe-leather
detective work
801
00:41:31,356 --> 00:41:34,657
as well as the understanding
of the importance
802
00:41:34,659 --> 00:41:36,993
of preserving evidence like DNA
803
00:41:36,995 --> 00:41:39,128
for the science of the future.
804
00:41:42,500 --> 00:41:44,901
[narrator]
After more than 20 years,
805
00:41:44,903 --> 00:41:48,438
Lisa continues to live on
in the memories of her family
806
00:41:48,440 --> 00:41:50,773
and the many friends
whose lives she touched.
807
00:41:52,009 --> 00:41:53,977
She was a force
to be reckoned with.
808
00:41:53,979 --> 00:41:55,545
Everyone loved her.
809
00:41:55,547 --> 00:41:58,748
She just really had a love
of life, and I admired that.
810
00:41:58,750 --> 00:41:59,749
And I just felt like,
811
00:41:59,751 --> 00:42:01,251
how could he
take her out like that?
812
00:42:01,253 --> 00:42:03,219
You know, brutal, senseless.
813
00:42:03,221 --> 00:42:04,621
And those are the kinds of cases
814
00:42:04,623 --> 00:42:06,456
that stick with you
as a homicide detective.
815
00:42:06,458 --> 00:42:07,590
Come on.
816
00:42:07,592 --> 00:42:09,392
[Shouldice] She had a lot
to bring to the world
817
00:42:09,394 --> 00:42:12,262
and you could see
her personality.
818
00:42:12,264 --> 00:42:16,065
And she was energetic and funny.
819
00:42:16,067 --> 00:42:17,099
[giggles]
820
00:42:17,101 --> 00:42:20,069
Very outgoing,
and I felt kind of privileged,
821
00:42:20,071 --> 00:42:22,972
in a way, to get
that glimpse of her.
822
00:42:22,974 --> 00:42:25,275
And I know that's how
her family remember her.
823
00:42:25,277 --> 00:42:27,310
And now it's how
I remember her, too.
