REPORTER: Prosecutors say Kimberly Lynn Cates,
42, a nurse and mother,
died of wounds to her head, torso,
arms, and legs.
Daughter, Jaimie, an 11-year-old
sixth grader, remains in intensive care,
her throat cut, a leg broken.
There are reports she managed to
call 911 after the attack for help.
We just kept saying to ourselves, "Why that,
you know, seemingly unassuming home?"

MAN: The thing inside of me, it's like...
the appetite -- it's like a wolf that's...
feeling the hunger.
REPORTER: New Hampshire State Troopers have just arrested
four individuals suspected for
the brutal murder of Kimberly Cates.
Her daughter, Jaimie, remains in critical condition.
Police were allegedly tipped off from multiple witnesses
reporting that four teenagers
were heard bragging about the murder to friends.
The suspects were identified as Steven Spader,
Christopher Gribble, Quinn Glover, and William Marks.
All four suspects are now in custody of the New Hampshire
State Police with charges pending.
Gribble's reaction to investigators,
when he's questioned about this brutal crime,
is inconsistent with how a lot of typical teenage boys
and teenagers would react.
He's very calm, he's very even in his tone.
But what he also is doing is he's impression managing.
He's trying to push a narrative on the investigators
about how he couldn't possibly
be someone that would do this, and that he's this upstanding
member of society.
Individuals, when they want to control the interview
or they want to manipulate the person that's
interviewing them, they'll dance around the question.
It is hypocritical, because just a few minutes ago,
he said, you know, "I'm chivalrous,"
implying, like, "I would be helpful if I could."
But here we see him later in the interview basically not
giving up any information,
being incredibly vague, insincere, and just all around
not helpful.
He's almost challenging them.
"Prove that you have anything on me.
Otherwise, you know, I'm walking out of here."
What the detective is starting to do is confront him,
and some of that is to see if Gribble cracks.
He doesn't show any real stress response.
He starts to laugh almost sarcastically.
This is also where we start to see
more and more of those psychopathic traits
really emerge.
He's not expressing any stress about what they know at all.
What we see is what we would expect to see
with most teenagers -- he's scared, there's not a lot
of energy, and he's somewhat defeated.
But what he is also is cooperative.
The minute you have a crime partner who's willing to talk,
you've got leverage, and most significantly and obviously,
what they now have is a witness.
You almost hear in Marks's account of this
that he's still in disbelief
that his friends really didn't have the same plan in mind.
It wasn't about robbing these two people.
They wanted to kill.
It was maybe indulging in and giving in on a fantasy
and an urge that they had both had for some time.
He is saying, "I'm not using being a sociopath as
an excuse,"
but he does disclose that he had the bad childhood,
which I feel is an excuse or some mitigation.
I think that he's also just grandiose,
and he wants to show them how smart he is.
Look, I have insight into myself.
Here's who I am.
SAHNI: What we know about Gribble
is in 2007, he had been in trouble
for sexually harassing and inappropriately
touching someone.
And in the process, his family took him to see a therapist.
One of the things that emerged was that he was off the scales
high and elevated in the domain that we think of as
sociopathy or psychopathy.
Oftentimes in media, we hear interchangeably
the term psychopath, the term sociopath.
And it's important to realize that for us as
forensic experts, we talk about it as psychopathy,
but they are the same terms.
DET 2: Yeah.
GRIBBLE: Umm...
FOX: Gribble is almost, uh, minimizing his culpability.
He's saying, "I'm not like that.
"I'm a better guy.
I just kill, and I just get it over with."
And it almost sounds like he's trying to juxtapose himself
with a way worse person,
belittling the fact that this was a gruesome,
horrific murder.
He's reliving it almost like somebody would be
feeling joy when they're retelling
about a family vacation.
He clearly enjoyed this, despite the butchery
and just how sadistic and inhumane this was,
and yet he's enjoying it.
And it's clear, as he's telling investigators,
I imagine if we could watch him as he's telling it,
he'd be smiling.
SAHNI: The fact that Gribble's first thought is to go back to
the fantasy of a horror movie
really speaks to the fact that these guys do
not live in reality.
They have really fused what is play-acting and made for TV
and movies and violence that is contrived for entertainment
purposes to that being their script.
Their way of navigating the world is this script
that they have crafted.
These teenagers can't wait to get home
and see whether there's any buzz.
They follow the news closely, they start talking to their
friends about what they did, and that's where we really start to
see the ego and the self-focus that this was a thrill kill.
What is important in this explanation he gives
the detective is while on the surface,
it sounds like there's a little empathy for this
child victim, he then very skillfully and sadly
turns this all back to himself.
And that's where we see the narcissism.
It's now about his own traumatic experiences,
his life as he sees it.
TUSSEY: Individuals with psychopathic traits do seek
stimulation, and they also may get an adrenaline
rush from hurting other people, or, you know,
they get a thrill and a rush out of seeking opportunities
that benefit them.
Had Gribble not gotten caught,
there are so many red flags that this would be
a repeat offense, that he could engage
in this type of behavior again.
SAVOY: Um...
Marks and Glover were attracted to Spader.
They weren't bothered by the idea of doing
a home invasion.
They weren't concerned about their future, and they had
a more antisocial outlook in life -- where Gribble fits into
this is that Gribble and Spader went back to childhood.
Their families went to church together, but somehow, that
disturbed thinking of homicidal urges was the nexus that may
have bonded Spader with Gribble.
TUSSEY: Christopher Gribble and Steven Spader seemed to be
like-minded in some ways,
very interested in looking out for number one,
very interested in achieving whatever they want to achieve,
however they need to do it,
robbing or hurting people if they need to.
So it may be, you know,
in a sense that individuals with similar psychopathic
traits sort of gravitate toward one another.
SAHNI: Once we escalate to trial, and we move forward,
Gribble makes claims that he's insane.
What we see is this complete failure to take responsibility
and a lack of willingness to take responsibility
for his crime.
GRIBBLE: I wanted to get out and have a real social life.
I wanted to torture my mom to death.
I'd get to the point at night where I just really wanted to
sneak in my dad's bedroom,
pull the gun out, and shoot myself in the head,
because I just wanted it to end.
MAN: You actually told Dr. Drukteinis about a month ago
that the people in the jail have no idea how dangerous you are.
No, they don't.
I smile, because it's funny that all
the people in there have no idea who they're messing with.
TUSSEY: So he's talking about wanting the social life
that he was deprived of,
but it's another indication of trying to
reject responsibility, like this wasn't all me.
Look, I'm a product of my environment.
I'm a product of my upbringing.
You know, I think this is performative.
I think he's enjoying being on the stage,
so to speak, of the courtroom.
WOMAN: I could go on for days and days
and days about the depth of your depravity.
But it is sufficient to say that you belong in a cage.
