00:06:11,116 theorized Chanin had been strangled 119 00:06:11,150 --> 00:06:15,830 and that affected how they collected evidence. 120 00:06:15,116 --> 00:06:17,330 We swabbed for DNA 121 00:06:17,660 --> 00:06:21,500 prior to moving Chanin's body from the crime scene. 122 00:06:21,830 --> 00:06:24,830 Narrator: But the most shocking part of this crime 123 00:06:24,116 --> 00:06:27,266 was what Chanin's killer did after the murder. 124 00:06:27,300 --> 00:06:30,500 Bryant: When cops come upon Chanin's body, 125 00:06:30,830 --> 00:06:31,166 the first thing that strikes them 126 00:06:31,200 --> 00:06:34,830 is how bizarre the positioning is. 127 00:06:35,000 --> 00:06:36,216 Shover: I'd never seen anything like this. 128 00:06:36,250 --> 00:06:40,160 I've never seen a dead body

did the attempt to clean up the crime scene. 132 00:06:49,216 --> 00:06:51,100 Johnston: All of the bedding has been removed, 133 00:06:51,133 --> 00:06:53,166 and it is in the wash machine. 134 00:06:53,200 --> 00:06:55,283 Whatever staining had been on the bedding 135 00:06:55,316 --> 00:06:57,333 is most likely removed in the wash, 136 00:06:57,366 --> 00:06:59,300 and so we're unable to match it up. 137 00:06:59,333 --> 00:07:04,250 Narrator: Oddly, for a crime with clear sexual motivations, 138 00:07:04,283 --> 00:07:06,333 Chanin had not been raped. 139 00:07:06,366 --> 00:07:11,133 The autopsy revealed petechial hemorrhages in Chanin's eyes -- 140 00:07:11,166 --> 00:07:15,266 confirmation that strangulation was the cause of death. 141 00:07:15,300 --> 00:07:19,200 And this gave investigators a possible break. 142 00:07:19,233 --> 00:07:21,300 There was something Chanin's killer 143 00:07:21,333 --> 00:07:24,183 apparently didn't realize. 144 00:07:24,216 --> 00:07:27,100 Chanin may have just taken a shower. 145 00:07:27,133 --> 00:07:30,216 Her hair looked like it was air-dried. 146 00:07:30,250 --> 00:07:34,116 Narrator: That meant her body might provide a good, 147 00:07:34,150 --> 00:07:38,333 freshly cleaned template for the killer's DNA. 148 00:07:38,366 --> 00:07:40,316 If there's any kind of suspicions 149 00:07:40,350 --> 00:07:44,660 that someone may have been manually strangled, 150 00:07:44,100 --> 00:07:48,216 typically, the medical examiner will take swabs of the neck. 151 00:07:48,250 --> 00:07:51,830 Narrator: While those swabs were being taken, 152 00:07:51,116 --> 00:07:54,166 detectives continued processing the scene. 153 00:07:54,200 --> 00:07:57,216 Soon, Chanin's ex-husband, Clay, 154 00:07:57,250 --> 00:07:59,116 who lived about a mile away, 155 00:07:59,150 --> 00:08:00,300 arrived. 156 00:08:00,333 --> 00:08:05,000 I told him that Chanin was found and that she was dead. 157 00:08:05,330 --> 00:08:09,383 And upon that news, he almost collapsed on the ground. 158 00:08:10,160 --> 00:08:11,830 Shover: He was very upset. 159 00:08:11,116 --> 00:08:12,350 Of course, he wanted to go in there. 160 00:08:12,383 --> 00:08:14,100 He wanted to see her. 161 00:08:14,133 --> 00:08:16,200 I told him he couldn't. 162 00:08:16,233 --> 00:08:17,366 It was a crime scene, 163 00:08:18,000 --> 00:08:22,100 and we were gonna secure the residence immediately. 164 00:08:22,133 --> 00:08:24,350 Narrator: Clay told police that Chanin 165 00:08:24,383 --> 00:08:28,160 had been out of contact for about two days, 166 00:08:28,500 --> 00:08:29,350 which was out of character, 167 00:08:29,383 --> 00:08:32,160 and a big problem for detectives. 168 00:08:32,500 --> 00:08:33,166 Johnston: At that particular time, 169 00:08:33,200 --> 00:08:36,383 we're not certain when Chanin was murdered. 170 00:08:37,160 --> 00:08:40,200 Narrator: And Chanin's autopsy didn't provide much help 171 00:08:40,233 --> 00:08:42,233 in narrowing that time frame. 172 00:08:42,266 --> 00:08:44,233 She was cold when found, 173 00:08:44,266 --> 00:08:47,233 so body temperature couldn't be used 174 00:08:47,266 --> 00:08:49,316 to nail down a time of death. 175 00:08:49,350 --> 00:08:54,500 This meant establishing alibis for potential suspects 176 00:08:54,830 --> 00:08:56,500 would be nearly impossible. 177 00:08:56,830 --> 00:08:58,300 For now, though, Clay Starbuck 178 00:08:58,333 --> 00:09:01,350 had a theory about who killed his ex-wife. 179 00:09:01,383 --> 00:09:04,500 Dresback: When I said, "Who do you think did it?" 180 00:09:04,830 --> 00:09:06,000 he said, "Just look on her computer 181 00:09:06,330 --> 00:09:07,216 and look on her phones." 182 00:09:07,250 --> 00:09:10,116 Maybe it had been an Internet date that had gone wrong. 183 00:09:10,150 --> 00:09:12,183 Narrator: A search of Chanin's cellphone 184 00:09:12,216 --> 00:09:18,500 provided vital information about her final days and hours. 185 00:09:18,830 --> 00:09:21,333 At 8:06 on the day she was last seen, 186 00:09:21,366 --> 00:09:25,330 she got a text from a man named Tom Walker. 187 00:09:25,660 --> 00:09:27,300 The two texted "Good morning" to each other. 188 00:09:27,333 --> 00:09:30,316 At 8:29, Tom made a request. 189 00:09:30,350 --> 00:09:32,383 Tom had sent a text to Chanin 190 00:09:33,160 --> 00:09:35,830 requesting that

body was found. 205 00:10:23,216 --> 00:10:27,100 We're using that as kind of the last known time 206 00:10:27,133 --> 00:10:29,160 we believe she's alive. 207 00:10:29,500 --> 00:10:31,216 Narrator: That timeline looked to clear Clay 208 00:10:31,250 --> 00:10:33,316 as a suspect in Chanin's murder. 209 00:10:33,350 --> 00:10:37,133 They know that Clay was with the kids from about 3:30 on. 210 00:10:37,166 --> 00:10:40,350 That creates a pretty tight window that would excuse Clay. 211 00:10:40,383 --> 00:10:44,333 Narrator: But it didn't do much for the chief suspect in this case -- 212 00:10:44,366 --> 00:10:45,350 Tom Walker. 213 00:10:45,383 --> 00:10:48,150 He and Chanin had met online, 214 00:10:48,183 --> 00:10:51,133 and he asked her to photograph herself 215 00:10:51,166 --> 00:10:54,133 in the exact same sexual pose 216 00:10:54,166 --> 00:10:57,660 in which her body was ultimately found. 217 00:10:57,100 --> 00:11:01,166 To detectives, this seemed like more than a coincidence. 218 00:11:01,200 --> 00:11:05,500 Tom admitted that he had made the request for the photograph. 219 00:11:05,830 --> 00:11:08,200 Narrator: Chanin didn't respond to this request. 220 00:11:08,233 --> 00:11:12,500 As for Tom Walker, he had no history of violence. 221 00:11:12,830 --> 00:11:14,300 But since analysts couldn't pin down 222 00:11:14,333 --> 00:11:17,100 Chanin's exact time of death, 223 00:11:17,133 --> 00:11:19,366 he was still a solid suspect. 224 00:11:20,000 --> 00:11:22,183 It's very common to have the time-of-death problem 225 00:11:22,216 --> 00:11:24,266 because the body doesn't necessarily tell you. 226 00:11:24,300 --> 00:11:27,200 Best you can get from a body is range. 227 00:11:27,233 --> 00:11:31,233 Narrator: Meanwhile, other searches of Chanin's communications 228 00:11:31,266 --> 00:11:34,183 uncovered a new potential suspect. 229 00:11:34,216 --> 00:11:36,350 His name was John Wilson. 230 00:11:36,383 --> 00:11:40,160 It didn't take very long to figure out 231 00:11:40,500 --> 00:11:42,350 that the John Wilson listed on Facebook 232 00:11:42,383 --> 00:11:44,166 was a fake profile 233 00:11:44,200 --> 00:11:47,133 and this person did not want to be found. 234 00:11:47,166 --> 00:11:51,350 Narrator: Using the e-mail address John Wilson gave to Chanin, 235 00:11:51,383 --> 00:11:54,100 detectives contacted him, 236 00:11:54,133 --> 00:11:57,383 and he refused to divulge his real identity. 237 00:11:58,160 --> 00:12:02,250 So, detectives did what's called a reverse directory 238 00:12:02,283 --> 00:12:07,200 on one of the numbers John Wilson used to call Chanin. 239 00:12:07,233 --> 00:12:11,333 It was traced to a pay phone outside a library 240 00:12:11,366 --> 00:12:14,500 at Washington State University. 241 00:12:14,830 --> 00:12:16,283 I mean, who uses pay phones anymore? 242 00:12:16,316 --> 00:12:19,233 Narrator: The answer, at least in this case, 243 00:12:19,266 --> 00:12:22,283 was someone who wanted to hide his identity 244 00:12:22,316 --> 00:12:25,330 and even his location. 245 00:12:25,660 --> 00:12:27,330 The problem for John Wilson 246 00:12:27,660 --> 00:12:29,116 was that there was a surveillance camera 247 00:12:29,150 --> 00:12:30,366 near this pay phone, 248 00:12:31,160 --> 00:12:35,183 and it recorded this image of someone walking to that phone 249 00:12:35,216 --> 00:12:37,300 at almost exactly the time 250 00:12:37,333 --> 00:12:42,133 records showed Chanin took the call. 251 00:12:42,166 --> 00:12:46,283 Investigators who were still contacting him by e-mail 252 00:12:46,316 --> 00:12:47,366 gave him a choice. 253 00:12:48,000 --> 00:12:50,383 He could voluntarily identify himself, 254 00:12:51,160 --> 00:12:54,266 or they could put his picture on TV 255 00:12:54,300 --> 00:12:57,216 and ask the public to identify him. 256 00:12:57,250 --> 00:13:00,333 With that, John Wilson came clean. 257 00:13:00,366 --> 00:13:03,100 His real name -- John Kenlein. 258 00:13:03,133 --> 00:13:07,330 And he had a good reason for trying to hide his identity. 259 00:13:07,660 --> 00:13:08,283 He's cheating on his wife. 260 00:13:08,316 --> 00:13:11,166 Narrator: Kenlein admitted contacting Chanin, 261 00:13:11,200 --> 00:13:13,350 and even said he went to her house 262 00:13:13,383 --> 00:13:17,830 during the period she dropped out of contact. 263 00:13:25,316 --> 00:13:28,116 Kenlein remained a solid suspect 264 00:13:28,150 --> 00:13:30,300 for the same reason Tom Walker did. 265 00:13:30,333 --> 00:13:35,250 Detectives still weren't sure exactly when Chanin was killed, 266 00:13:35,283 --> 00:13:39,150 so they couldn't alibi any of their suspects. 267 00:13:39,183 --> 00:13:42,160 Bryant: Chanin was seen when she dropped the kids off, 268 00:13:42,500 --> 00:13:45,200 and then her body not found for almost three days later. 269 00:13:45,233 --> 00:13:48,316 Narrator: But then, to the surprise of everyone, 270 00:13:48,350 --> 00:13:51,133 a new piece of evidence emerged. 271 00:13:51,166 --> 00:13:52,366 Johnston: I find a 911 call, 272 00:13:53,000 --> 00:13:57,200 which was something that we were never aware of in the past. 273 00:13:58,133 --> 00:14:00,216 Operator: 911.
