WEBVTT - The Days After Death 0:00:04.320 --> 0:00:08.840 Investigators believe Coburger killed Kaylei Gansalves, Madison Mogan, Zeyner, Kernodle, 0:00:09.080 --> 0:00:11.760 and Ethan Chapin inside of a rented home not far 0:00:11.800 --> 0:00:14.280 from the University of Idaho campus. At the time of 0:00:14.320 --> 0:00:17.400 the murders, Coburger was studying at Washington State University, which 0:00:17.440 --> 0:00:20.440 is just a few miles away from the crime scene. 0:00:21.400 --> 0:00:26.080 Outside Coberger's apartment in Pullman, Washington, detectives removing boxes and 0:00:26.239 --> 0:00:28.840 bags from the apartment. They just kept coming out with 0:00:28.920 --> 0:00:31.240 more and more stuff and loading it into evidence vans. 0:00:31.400 --> 0:00:33.599 But in that list of what they brought out, they 0:00:33.640 --> 0:00:36.519 do not list knife in that evidence list. 0:00:42.159 --> 0:00:47.200 This is the Idaho Massacre, a production of KT Studios 0:00:47.320 --> 0:00:56.480 and iHeartRadio, episode five The Days After Death. Courtney Armstrong 0:00:56.600 --> 0:01:01.200 a television producer at KT Studios with Stephanie Leidecker, Jeff Shane, 0:01:01.240 --> 0:01:08.720 and Connor Powell. When Brian Colberger moved to Pullman, Washington 0:01:08.920 --> 0:01:11.800 in early July of twenty twenty two for his pH 0:01:11.920 --> 0:01:15.319 d program, he arrived on campus with his dad driving 0:01:15.319 --> 0:01:21.120 a twenty fifteen white Hondi Atlantra. Within months of arriving 0:01:21.160 --> 0:01:25.560 on campus, Coburger was pulled over by Washington State University Police. 0:01:26.200 --> 0:01:29.640 Hello, Hi, am, officer langis stops being audio and video recorded. 0:01:29.720 --> 0:01:31.640 You think you know why I stopped you. As the 0:01:31.680 --> 0:01:34.720 officer approached the driver's side window, the twenty eight year 0:01:34.720 --> 0:01:40.640 old criminology student respectfully greeted her. Colberger explained he was 0:01:40.680 --> 0:01:43.920 originally from a rural area in Pennsylvania and was new 0:01:43.959 --> 0:01:46.959 to the area. He said he accidentally got caught in 0:01:47.000 --> 0:01:49.760 the intersection before turning left on a red light. 0:01:51.160 --> 0:01:53.240 Yeah, it was a little bit of confusion with speeding 0:01:53.320 --> 0:01:55.760 because someone had stopped. 0:01:56.120 --> 0:01:57.840 I wasn't sure what they were doing. 0:01:58.280 --> 0:02:01.600 During the nine and a half minute interaction, Coburger politely 0:02:01.640 --> 0:02:05.280 asked the female officer to explain Washington State's traffic laws, 0:02:05.600 --> 0:02:09.560 before he apologized for asking too many questions. Do you 0:02:09.560 --> 0:02:10.880 have your license on you? 0:02:12.080 --> 0:02:12.160 You? 0:02:12.360 --> 0:02:13.840 Do you have the registration and insurance? 0:02:15.520 --> 0:02:17.000 I'm just going to this off route, Okay. 0:02:17.520 --> 0:02:20.839 The traffic stop was unremarkable and Coburger was let off 0:02:20.840 --> 0:02:24.119 with a warning, But during the brief exchange, which took 0:02:24.160 --> 0:02:27.640 place one month before the murderers, the officer commented that 0:02:27.680 --> 0:02:31.200 Brian Coberger's vehicle registration was set to expire in a 0:02:31.240 --> 0:02:32.200 few months. 0:02:32.960 --> 0:02:36.359 Let's see expires November twenty second, twenty twenty two. 0:02:36.720 --> 0:02:40.480 For the next month Coburger's wife twenty fifteen, Atlantra remained 0:02:40.520 --> 0:02:43.839 registered in his home state of Pennsylvania, But five days 0:02:43.880 --> 0:02:47.040 after the gruesome murders, Coburger did something he hadn't done 0:02:47.080 --> 0:02:51.920 for months. He changed his registration from Pennsylvania to Washington 0:02:52.080 --> 0:02:55.480 and received new license plates. Was this simply a coincidence, 0:02:55.919 --> 0:02:58.320 a last minute chore that needed to be completed but 0:02:58.400 --> 0:03:01.640 had escaped Coburger's mind ring his first and very busy 0:03:01.760 --> 0:03:05.440 fall semester. Or was this one of the many actions 0:03:05.480 --> 0:03:08.440 Coburger took to try to cover his tracks after killing 0:03:08.520 --> 0:03:14.280 the four University of Idaho students. Here's Stephanie and Jeff. 0:03:15.400 --> 0:03:19.000 It was roughly seven weeks from the time Kaylee, Madison, Zana, 0:03:19.160 --> 0:03:22.760 and Ethan were killed to the time Brian Coburger was arrested. 0:03:23.360 --> 0:03:25.799 To me, the biggest question in this case is obviously 0:03:25.880 --> 0:03:28.760 why did Coburger, if in fact he is guilty, commit 0:03:28.800 --> 0:03:29.200 this crime? 0:03:29.560 --> 0:03:34.160 And maybe asking ourselves why is an impossible question. It's 0:03:34.280 --> 0:03:38.080 kind of applying reason to an irrational situation. Whoever did 0:03:38.120 --> 0:03:41.440 this is obviously a monster, and we're clearly not going 0:03:41.480 --> 0:03:43.480 to be able to assign logic to that person. 0:03:43.880 --> 0:03:46.520 The other good question I have is what was Coburger 0:03:46.560 --> 0:03:48.400 doing in the days and weeks leading up to the 0:03:48.480 --> 0:03:49.840 murders exactly? 0:03:49.920 --> 0:03:52.400 And there are so many unanswered questions at this point, 0:03:52.640 --> 0:03:55.480 but thanks to the Probable Cause AffA David, we do 0:03:55.680 --> 0:03:58.840 know some of the movements and actions of Coburger. 0:04:01.240 --> 0:04:03.480 Brian Coburger's cell phone is at the center of the 0:04:03.480 --> 0:04:06.760 prosecution's case against the twenty eight year old in the 0:04:06.880 --> 0:04:10.400 days and hours before and after the killings, Investigators say 0:04:10.440 --> 0:04:13.520 Coburger's cell phone use paints a disturbing picture of a 0:04:13.600 --> 0:04:17.400 killer stalking his victims and returning to the scene of 0:04:17.400 --> 0:04:17.839 the crime. 0:04:19.520 --> 0:04:22.599 Investigators say they believe the murders took place between four 0:04:22.640 --> 0:04:24.400 and four to twenty five am. 0:04:24.440 --> 0:04:27.560 According to cell phone data, Coburger's phone was connected to 0:04:27.600 --> 0:04:31.240 the cellular network near his apartment in Pulman, Washington, at 0:04:31.279 --> 0:04:34.560 four forty two am on the morning of the murders. 0:04:34.960 --> 0:04:38.040 His phone disappeared from the network and was switched off 0:04:38.080 --> 0:04:41.440 between two forty seven am and four forty eight a m. 0:04:41.640 --> 0:04:44.440 On the morning of the murders. Police say in the 0:04:44.440 --> 0:04:48.840 Probable Cause Affidavid that this is quote consistent with Coburger 0:04:48.920 --> 0:04:55.239 attempting to conceal his location during the quadruple homicide. Here's 0:04:55.279 --> 0:04:57.160 reporter Chris Bargo. 0:04:58.279 --> 0:05:01.320 At two forty two in the morning. Brian Coburger's cell 0:05:01.320 --> 0:05:04.119 phone is recorded as sort of being on the network 0:05:04.120 --> 0:05:07.040 in Pullman, Washington, where his dormitory is on Washington State 0:05:07.120 --> 0:05:09.600 University campus. Then a few minutes later goes off the 0:05:09.640 --> 0:05:13.760 network and is disconnected. From that point on, there's just 0:05:14.000 --> 0:05:16.120 counts of people seeing his white hand lantro, so his 0:05:16.120 --> 0:05:18.440 white han day luntra scene leaving Pullman shortly after that, 0:05:18.839 --> 0:05:22.400 and then around three point thirty itt scene in Moscow. Now, 0:05:22.440 --> 0:05:25.120 the direct route from Pullman to Moscow is about fifteen 0:05:25.120 --> 0:05:26.760 minutes tops, and this is late at night, so it's 0:05:26.800 --> 0:05:29.120 not going to be any traffic. So it's assumed he 0:05:29.160 --> 0:05:31.279 took some sort of way that would have gone around 0:05:31.320 --> 0:05:33.120 that sort of main road. He would either went up 0:05:33.240 --> 0:05:35.320 north or he went down south and took back rows 0:05:35.360 --> 0:05:37.920 to sort of get there. Because the alleged killer is driving, 0:05:38.640 --> 0:05:41.960 police belief from Pullman to Moscow, if it is indeed Brian, 0:05:42.160 --> 0:05:43.920 that would suggest that it was targeted because that's a 0:05:44.000 --> 0:05:46.000 very specific target. That's a very specific house he's going to. 0:05:48.279 --> 0:05:51.960 At four forty eight am, Coberger's phone comes back online 0:05:52.240 --> 0:05:55.760 and pings a tower just south of Moscow. But police 0:05:55.800 --> 0:05:59.520 say Coburger did not head straight home. Instead, he drove 0:05:59.560 --> 0:06:02.600 a back roads route which was longer and more remote. 0:06:04.520 --> 0:06:06.960 That area that he drove south to where he the 0:06:07.040 --> 0:06:09.200 road sort of goes down south about ten or twenty 0:06:09.240 --> 0:06:10.680 miles and then it turns back up in a u. 0:06:11.160 --> 0:06:14.039 That area at the bottom is just mountains and it's forest. 0:06:14.480 --> 0:06:16.480 He arrives home at five point thirty in the morning, 0:06:16.680 --> 0:06:20.480 where the WSU campus surveillance video captures his white Atlanta 0:06:20.640 --> 0:06:24.599 returning home. A few hours later, Coburger's phone is back 0:06:24.640 --> 0:06:29.000 on the move. In a particularly chilling move, Coburger's phone 0:06:29.040 --> 0:06:31.160 pings a tower near the King roadhouse. 0:06:34.320 --> 0:06:38.120 Ryan Coberger's saleshone allegedly shows him here at nine to 0:06:38.160 --> 0:06:41.839 twelve am and staying for about ten minutes. 0:06:42.839 --> 0:06:46.039 Surveillance video also shows a white Sedan driving past the 0:06:46.080 --> 0:06:50.120 scene of the murders around nine in the morning. Police 0:06:50.160 --> 0:06:52.880 have yet to be called to the gruesome murder scene. 0:06:55.520 --> 0:06:56.720 Stephanie and Jeff. 0:06:57.720 --> 0:07:01.320 It's the oldest cliche in criminal history, the killer always 0:07:01.360 --> 0:07:02.880 returns to the scene of the crime. 0:07:03.320 --> 0:07:07.400 Well, actually, Steph, it's not true for most killers. Many 0:07:07.480 --> 0:07:10.280 serial killers do actually return to the scene of the crime, 0:07:10.320 --> 0:07:13.400 particularly ones who are compulsive or obsessed over their victims. 0:07:13.440 --> 0:07:16.200 For example, Gary Ridgway, who was known as the Green 0:07:16.280 --> 0:07:19.920 River Killer and convicted of forty nine murders, regularly returned 0:07:19.920 --> 0:07:22.720 to the spots he dumped his victims' bodies. Also the 0:07:22.760 --> 0:07:25.360 son of Sam killer David Berkowitz. He told the FBI 0:07:25.400 --> 0:07:27.400 that on nights he couldn't find a victim, he would 0:07:27.400 --> 0:07:29.880 just go back to the scene of previous kills and masturbate. 0:07:30.400 --> 0:07:33.360 That's so sick, I mean, think about it. Returning to 0:07:33.400 --> 0:07:35.440 the scene of the crime is usually part of a 0:07:35.480 --> 0:07:39.760 pattern with killers who are extremely confident and pride themselves 0:07:39.800 --> 0:07:43.480 on being kind of untouchable by law enforcement and basically 0:07:43.560 --> 0:07:46.920 smarter than everybody else. Does that sound like coburger to you. 0:07:47.480 --> 0:07:49.840 Here's Jeff speaking with Adam Wand. 0:07:49.880 --> 0:07:52.120 I'm not a criminology student, but I've seen enough law 0:07:52.120 --> 0:07:54.160 in order to know, like, your cell phone is how 0:07:54.200 --> 0:07:56.080 people track you. And he's like dumb enough to bring 0:07:56.080 --> 0:07:57.880 the phone or turn it on on the way home, 0:07:57.880 --> 0:07:59.320 like he didn't even get all the way home. What 0:07:59.360 --> 0:08:01.880 do you make of his lack of good decisions? 0:08:02.320 --> 0:08:06.440 We have a wonderful idiom in English for his behavior, 0:08:06.720 --> 0:08:11.000 and the idiom is a little bit of knowledge is deadly. 0:08:14.200 --> 0:08:17.280 Adam Want is a digital forensics expert and a professor 0:08:17.320 --> 0:08:21.360 at John Jay College of Criminal Justice. He spoke to 0:08:21.400 --> 0:08:24.160 producer Jeff Shane about how a cell phone can be 0:08:24.240 --> 0:08:27.960 used to establish Kolberger's actions and whereabouts in the immediate 0:08:28.000 --> 0:08:29.600 hours surrounding the killings. 0:08:30.320 --> 0:08:34.000 I think in this specific case, the little bit of 0:08:34.120 --> 0:08:38.600 knowledge he had really hurt him. That little bit of 0:08:38.640 --> 0:08:42.319 knowledge was if I bring my cell phone to the 0:08:42.360 --> 0:08:45.880 scene of the crime, I could be identified as being 0:08:45.920 --> 0:08:49.319 there with my cell phone. And he was right. If 0:08:49.360 --> 0:08:51.440 he brought his cell phone there while it was on, 0:08:52.280 --> 0:08:56.320 we would have much quicker figured out who he was 0:08:56.520 --> 0:08:59.040 and had been able to arrest him. But what he 0:08:59.120 --> 0:09:03.239 did was smart to him. He turned off his phone beforehand, 0:09:03.280 --> 0:09:06.600 he turned it back on afterwards, And if we never 0:09:06.800 --> 0:09:11.680 identified him as a possible suspect, we may never have 0:09:11.800 --> 0:09:14.719 figured out it was actually him because he turned off 0:09:14.760 --> 0:09:18.559 his phone. But once we realize he's a potential suspect, 0:09:18.800 --> 0:09:21.640 and once we see he turned his phone off right 0:09:21.679 --> 0:09:25.079 before that period of time turned it back on shortly 0:09:25.120 --> 0:09:28.240 after that period of time. That's what we call an 0:09:28.360 --> 0:09:33.160 overt action that he took that the jury could look 0:09:33.200 --> 0:09:37.680 at to determine guilt. So ultimately, what he did to 0:09:37.880 --> 0:09:42.840 protect himself because he didn't understand that these issues fully 0:09:43.320 --> 0:09:46.200 actually might be one of the most important pieces of 0:09:46.240 --> 0:09:48.000 information that she used to convict him. 0:09:48.440 --> 0:09:51.760 Because it looks suspicious that his phone turns off for 0:09:51.840 --> 0:09:54.520 this window of time and then turns back on on 0:09:54.559 --> 0:09:56.000 the border of between these two towns. 0:09:56.760 --> 0:09:59.640 Some people might say it looks suspicious that his phone 0:09:59.679 --> 0:10:03.200 turned off and then back on again. I go beyond that. 0:10:03.360 --> 0:10:08.880 It's not just suspicious. He took an action that was 0:10:08.920 --> 0:10:12.959 recorded on his phone. His phone would have recorded him 0:10:13.000 --> 0:10:16.240 turning it off and recorded where he was. And the 0:10:16.280 --> 0:10:18.840 fact that he turned it off and then where he was, 0:10:18.880 --> 0:10:20.959 and the fact that he turned it back on again, 0:10:21.480 --> 0:10:25.440 and the fact that he took the time to turn 0:10:25.480 --> 0:10:27.920 off his phone shortly before the murders and turn it 0:10:28.000 --> 0:10:31.840 right back on shortly after the murders certainly shines a 0:10:31.960 --> 0:10:36.120 spotlight on him that's going to be very hard to reboot. 0:10:36.440 --> 0:10:37.800 He did not turn his phone off at all when 0:10:37.800 --> 0:10:39.560 he drove back any of the other times that he 0:10:39.600 --> 0:10:40.199 had been there. 0:10:40.640 --> 0:10:46.760 Let's face it, a stable, emotionally mature, sane person is 0:10:46.920 --> 0:10:49.960 not going to go kill a houseful of people. In 0:10:50.000 --> 0:10:55.600 this particular case, if the suspect is the murderer, then 0:10:55.720 --> 0:11:01.160 he's probably not completely sane and stable, and things that 0:11:01.200 --> 0:11:04.679 he did, good or bad are going to come up 0:11:04.760 --> 0:11:07.400 in the trial and come up in evidence, and a 0:11:07.440 --> 0:11:09.120 lot of that evidence is going to be used by 0:11:09.160 --> 0:11:10.840 the jury to figure out if he's guilty or not. 0:11:13.240 --> 0:11:15.760 Did Coburger return to the house to try and gather 0:11:15.840 --> 0:11:18.960 evidence such as the knife sheath that he allegedly left 0:11:19.000 --> 0:11:21.880 in the house, or did he return to relive the 0:11:21.960 --> 0:11:27.560 murders like other overconfident killers, or to admire what he'd done. 0:11:29.720 --> 0:11:31.760 Let's stop here for a break. We'll be back in 0:11:31.800 --> 0:11:42.679 a moment. After revisiting the crime scene and returning home, 0:11:42.840 --> 0:11:46.080 Brian Coberger's day was far from over. According to the 0:11:46.080 --> 0:11:50.080 probable Cause Affidavid Coburger's cellphone data shows he drove south 0:11:50.080 --> 0:11:54.520 from Pullman, Washington to Lewiston, Idaho. The fifty minute drive 0:11:54.679 --> 0:11:57.080 was just the beginning of a day of strange movements. 0:11:57.200 --> 0:12:02.559 Following the murders, six pm, Coburger arrives at an Albertson's 0:12:02.600 --> 0:12:04.120 grocery store in Lewiston. 0:12:05.000 --> 0:12:09.559 Surveillance video at twelve forty nine pm shows Coburger walking 0:12:09.600 --> 0:12:13.840 through the store and purchasing unknown items at the checkout. 0:12:14.280 --> 0:12:19.280 He leaves about fifteen minutes later. Here again, Jeff and Stephanie. 0:12:19.840 --> 0:12:22.200 So why does Brian Coburger make the long drive and 0:12:22.280 --> 0:12:25.400 go to Lewiston, Idaho for some groceries? Polman has stores 0:12:25.440 --> 0:12:27.960 like Safeway and Walmart. In fact, SODA's nearby Moscow. It 0:12:28.000 --> 0:12:31.239 also has a Safeway, a Walmart, and a Target and Adulatry. 0:12:31.520 --> 0:12:33.360 And what does he need from the grocery store in 0:12:33.440 --> 0:12:36.160 Lewiston that he can't get in Pullman or Moscow? 0:12:36.720 --> 0:12:39.600 You know what this reminds me of is Angela Wagner, who, 0:12:39.679 --> 0:12:42.320 along with her husband and two sons, murdered eight members 0:12:42.320 --> 0:12:44.840 of the Rodent family in twenty sixteen. When planning the murders, 0:12:44.880 --> 0:12:47.280 she drove hours away from her house in Pike County 0:12:47.360 --> 0:12:49.760 to get supplies for the murders. She thought she was 0:12:49.800 --> 0:12:53.040 somehow outsmarting detectives by going far away, but thanks to 0:12:53.400 --> 0:12:56.200 very trusty surveillance footage they caught her right handed. Could 0:12:56.200 --> 0:12:59.160 Coburger have been buying something like bleach or other cleaning 0:12:59.200 --> 0:13:02.240 supplies he didn't want copseeing and somehow thought buying it 0:13:02.360 --> 0:13:04.360 far away from where he lived or where the murders 0:13:04.400 --> 0:13:05.720 took place would throw them off. 0:13:06.320 --> 0:13:10.240 Also, Lewiston is located at the confluence of the Snake 0:13:10.360 --> 0:13:13.360 River and the Clearwater River, so if he was trying 0:13:13.360 --> 0:13:16.599 to maybe dispose of a murder weapon like a knife, 0:13:16.760 --> 0:13:19.760 these big rivers would kind of be an ideal spot. 0:13:23.120 --> 0:13:26.600 According to the police Affidavid, Coburger's phone pins a cell 0:13:26.679 --> 0:13:30.240 tower in Johnson, Idaho, roughly four hours later at five 0:13:30.240 --> 0:13:31.400 point thirty pm. 0:13:31.880 --> 0:13:34.040 Let's unpack that a bit, because this is a really 0:13:34.080 --> 0:13:37.800 important fact. There actually is no Johnson, Idaho. 0:13:38.440 --> 0:13:38.680 Yeah. 0:13:38.720 --> 0:13:41.079 Our friends Deanna Thompson and John Green from our new 0:13:41.120 --> 0:13:45.160 podcast True Crimes pointed out that the Affidavid likely meant 0:13:45.200 --> 0:13:48.600 nearby Johnson, Washington. The town of Johnson is just off 0:13:48.600 --> 0:13:52.720 the highway between Lewiston, Idaho, where Coburger went shopping, and Pullman, Washington, 0:13:52.720 --> 0:13:55.040 where he lived. It's also on the route investigator say 0:13:55.040 --> 0:13:57.120 Coburger traveled after the murders. 0:13:57.000 --> 0:13:59.960 And remember, according to officials, he didn't take the shwe 0:14:00.240 --> 0:14:03.720 direct road between Moscow and Pullman. He took the back 0:14:03.800 --> 0:14:05.440 road country roads instead. 0:14:06.000 --> 0:14:08.679 Later that day, on Sunday, November thirteenth, at five point 0:14:08.679 --> 0:14:12.280 thirty six pm, for three hours, Coburger's phone once again 0:14:12.440 --> 0:14:15.160 was disconnected from cell service. Think about it. This was 0:14:15.160 --> 0:14:18.080 a Sunday in November. It's cold, there's NFL on TV. 0:14:18.480 --> 0:14:22.600 Coburger is busy with his PhD and TA work. This 0:14:22.680 --> 0:14:25.000 is a long time to just be driving around aimlessly, 0:14:25.200 --> 0:14:26.520 especially without your cell phone. 0:14:26.680 --> 0:14:29.160 What was he doing and where was he going? Could 0:14:29.200 --> 0:14:31.560 he have been moving and trying to get rid of evidence? 0:14:37.000 --> 0:14:40.080 Following the murders people who interacted with Coburger so a 0:14:40.120 --> 0:14:44.480 dramatic change in his personality. Before the killings, Coburger was 0:14:44.520 --> 0:14:48.120 disliked by his students at Washington State University, who viewed 0:14:48.200 --> 0:14:51.760 him as strange and remote. Here is Hayden Stinchfield, a 0:14:51.800 --> 0:14:55.160 former student of Coburger's. 0:14:56.280 --> 0:14:58.680 When he came into class, he was very, you know, 0:14:58.840 --> 0:15:00.920 not super mentally present. He would stand up the front 0:15:00.920 --> 0:15:02.920 look at the ground. He had a lot of like 0:15:02.920 --> 0:15:05.640 boiler plate responses he would give people rather than you know, 0:15:05.840 --> 0:15:07.280 maybe something he had thought up on the spot. It 0:15:07.320 --> 0:15:09.280 seemed like he would be you know, he'd come in 0:15:09.320 --> 0:15:11.480 knowing what he was going to say to Like most interactions. 0:15:11.840 --> 0:15:15.680 As a teaching assistant, Coburger was disliked by undergraduates because 0:15:15.680 --> 0:15:19.400 of his difficult grading and condescending tone. He was also 0:15:19.440 --> 0:15:23.840 accused of being sexist and acting inappropriately towards female students. 0:15:24.320 --> 0:15:27.400 One young woman said he creepily followed her to her car. 0:15:28.040 --> 0:15:31.800 Following the murders, Coburger's behavior towards women did not change, 0:15:32.240 --> 0:15:34.640 but his grading style did about a. 0:15:34.600 --> 0:15:38.000 Month before winter break, when like the murders happened. Definitely 0:15:38.040 --> 0:15:41.640 around then he started grading everybody just a hundreds, not 0:15:41.840 --> 0:15:44.000 like like like you pretty much if you turned something 0:15:44.040 --> 0:15:47.000 in you were getting high marked, and he stopped leaving notes. 0:15:47.040 --> 0:15:50.360 It was just, you know, he seemed preoccupied. 0:15:50.440 --> 0:15:51.160 It was much easier. 0:15:51.160 --> 0:15:53.040 You'd turn in whatever you wanted pretty much, and he 0:15:53.120 --> 0:15:54.840 was just braiding them up and sending them back. 0:15:55.080 --> 0:15:58.160 Hayden Stenfield also said around the time of the murders, 0:15:58.240 --> 0:16:00.440 Coburger's appearance changed well. 0:16:00.800 --> 0:16:03.120 Around that time period. I remember him, you know, he 0:16:03.160 --> 0:16:05.320 had like a little bit more facial hair, just like stubble, 0:16:05.400 --> 0:16:08.560 but definitely less like well kept than he was. And 0:16:08.640 --> 0:16:11.680 he was a little quieter, you know, he didn't he 0:16:11.800 --> 0:16:13.280 used to stand up at the start of class and 0:16:13.320 --> 0:16:15.160 like talk about some stuff sometimes, and this time he 0:16:15.160 --> 0:16:16.240 didn't really do that at all. 0:16:16.640 --> 0:16:19.920 One of Coberger's fellow graduate students, speaking to the media 0:16:20.240 --> 0:16:23.000 also noticed a distinct change following the murders. 0:16:23.600 --> 0:16:25.160 I did notice that he was, you know, he was 0:16:25.160 --> 0:16:27.640 cowing up to class a little late sometimes. He always 0:16:27.640 --> 0:16:29.880 had a coffee in hand. He always seemed to be 0:16:30.080 --> 0:16:36.160 just perpetually exhausted. Like everybody in a graduate program, there's 0:16:36.160 --> 0:16:37.880 a little bit of awkwardness. You're trying to fit in. 0:16:37.880 --> 0:16:41.240 You're trying to find Denise and Brian cobol little fit 0:16:41.280 --> 0:16:43.320 in that he was awkward. He was trying to fit in. 0:16:43.360 --> 0:16:47.000 He was trying to get his inroad into this group 0:16:47.000 --> 0:16:50.080 and establish these social bonds with other members of the cohort. 0:16:50.360 --> 0:16:52.880 He did seem to get a little chattiol going into 0:16:52.880 --> 0:16:53.720 the Lattle pul to the. 0:16:53.680 --> 0:16:58.840 Tomb again, Stephanie and Jeff. 0:16:59.600 --> 0:17:02.520 Let's put us into perspective. Around this time, Coburger was 0:17:02.600 --> 0:17:05.080 under a lot of stress from WSU. His boss was 0:17:05.119 --> 0:17:06.840 not at him, and he was about to get fired. 0:17:07.040 --> 0:17:09.760 Not to mention, he must have known that the cops 0:17:09.760 --> 0:17:12.119 were circling in on him in some capacity. Could all 0:17:12.119 --> 0:17:13.760 that stress have been catching up to him. 0:17:14.080 --> 0:17:17.040 Let's just go through the list. He's changing his appearance. 0:17:17.520 --> 0:17:21.720 He's disinterested in work, he's preoccupied at school, he's behaving 0:17:21.920 --> 0:17:26.119 very overwhelmed. Clearly some thing's going on. Is he just 0:17:26.240 --> 0:17:28.360 overwhelmed because it's the end of the year and it's 0:17:28.400 --> 0:17:31.760 before the holidays and that's an intense time for many 0:17:32.480 --> 0:17:36.159 or is he behaving like somebody who's just committed mass murder. 0:17:36.560 --> 0:17:38.320 I agree with that, but I will also say that 0:17:38.359 --> 0:17:40.760 the fact he was being extra chatty is so strange 0:17:40.760 --> 0:17:41.000 to me. 0:17:46.680 --> 0:17:50.959 When Brian Colberger was arrested in Pennsylvania, investigators also searched 0:17:50.960 --> 0:17:55.280 his apartment in Pullman, Washington. Here's reporter Chris Bargo. 0:17:55.680 --> 0:17:57.800 His apartment is certainly very cleaned out. He did leave 0:17:57.800 --> 0:18:00.399 a few things like a TV. His storagelock grivid had 0:18:00.440 --> 0:18:03.040 ever been used. Was completely cleaned out. There's no shower 0:18:03.119 --> 0:18:05.320 curtain when police go their first search, and there's really 0:18:05.400 --> 0:18:07.240 very few things inside this apartment that make it seems 0:18:07.240 --> 0:18:09.280 like someone's living there. It almost seems like you just 0:18:09.359 --> 0:18:11.240 left beyond some trash. Maybe are the things he didn't want, 0:18:11.480 --> 0:18:13.800 but we're not sure. He also manages to clear it 0:18:13.800 --> 0:18:16.240 out before authorities get any sort of search warrant or 0:18:16.280 --> 0:18:18.760 any sort of identifying him as really as the suspect 0:18:18.760 --> 0:18:22.960 of the case, so when they finally get to search 0:18:22.960 --> 0:18:25.439 out apartment, he's cleared it out, so it's not The 0:18:25.480 --> 0:18:28.200 potential for evidence has probably been decreased drastically because he'd 0:18:28.200 --> 0:18:29.760 been gone more than two weeks actually by the time 0:18:29.760 --> 0:18:30.479 they searched it. 0:18:32.880 --> 0:18:36.119 Had Brian Coberger always lived such a bare bones existence, 0:18:36.800 --> 0:18:39.600 or was his Washington apartment empty because he had stripped 0:18:39.600 --> 0:18:45.480 it clean and removed anything that might have incriminated him. 0:18:45.680 --> 0:18:49.879 Stephanie and Jeff I remember being a student. You know 0:18:49.920 --> 0:18:52.040 you're kind of broke, So it does stand to reason 0:18:52.080 --> 0:18:55.640 that his place wouldn't be opulent and lavish. 0:18:55.720 --> 0:18:58.800 But no shower curtain, that is just odd. I'm thinking 0:18:58.840 --> 0:19:00.720 he could have used it in his the night of 0:19:00.720 --> 0:19:02.800 the murder to keep blood off the seats. 0:19:03.080 --> 0:19:06.280 Like the TV show Dexter, where he would use plastic 0:19:06.520 --> 0:19:09.320 to keep any incriminating evidence away. 0:19:12.240 --> 0:19:15.600 Three weeks after his arrest, the search warrant for Coberger's 0:19:15.640 --> 0:19:19.520 apartment was unsealed by a judge. It detailed what forensic 0:19:19.600 --> 0:19:20.760 teams had found. 0:19:21.200 --> 0:19:24.760 Investigators removed several items from inside that apartment. 0:19:27.160 --> 0:19:30.560 Among the items possibly connecting Coburger to his victims were 0:19:30.600 --> 0:19:34.280 a single black surgical type glove, the dust container from 0:19:34.400 --> 0:19:39.240 Coburger's Bissel power force vacuum, a computer tower, a collection 0:19:39.480 --> 0:19:43.360 of dark red spots, several strands of hair, including one 0:19:43.359 --> 0:19:47.960 investigator's believe is from an animal, multiple store receipts, including 0:19:48.000 --> 0:19:51.480 one from Walmart with the Dickey's tag, and two clippings 0:19:51.480 --> 0:19:55.639 from a pillow that contained a reddish brown stain. Shortly 0:19:55.680 --> 0:19:58.840 after Brian Coberger became the lone suspect in the brutal 0:19:58.920 --> 0:20:02.480 quadruple murders, he departed on a cross country trip back 0:20:02.520 --> 0:20:05.920 home to Pennsylvania with his father. The fall semester had 0:20:05.960 --> 0:20:09.720 just finished and Coburger was heading home for the holidays. However, 0:20:10.000 --> 0:20:12.880 after months of conflict with the faculty in the criminology 0:20:12.920 --> 0:20:17.120 department over his behavior as a teaching assistant, Coburger's academic 0:20:17.200 --> 0:20:21.040 career is in doubt. Just a few days after he 0:20:21.119 --> 0:20:24.640 departed campus, Coburger would receive a letter from the school 0:20:24.800 --> 0:20:27.439 saying that his job as a teaching assistant would be 0:20:27.520 --> 0:20:32.280 terminated and his return to WSU was very much in doubt. 0:20:32.680 --> 0:20:37.320 Here's reporter Chris Bargo, what do you make of the 0:20:37.320 --> 0:20:39.080 car ride home with his dad? 0:20:39.800 --> 0:20:41.639 So we know the dad drove him out, so I 0:20:41.680 --> 0:20:44.800 would assume that's probably always the plan. I don't understand 0:20:44.840 --> 0:20:46.960 why you drive home though, if you're coming back, because 0:20:46.960 --> 0:20:48.400 it seems like to have your car for four weeks 0:20:48.400 --> 0:20:50.240 in Pennsylvania to drive all that way and then all 0:20:50.280 --> 0:20:51.680 the way back out, that's a pain in the ass. 0:20:51.720 --> 0:20:53.360 And that's a lot of miles on the car. That's 0:20:53.359 --> 0:20:55.520 not really a new car. So probably just keep it 0:20:55.520 --> 0:20:57.600 at the school. But we don't know. I mean, obviously 0:20:57.600 --> 0:20:59.080 the dad isn't talking. We don't know when he decided 0:20:59.080 --> 0:21:01.280 to do it. But again, that's something you could probably 0:21:01.280 --> 0:21:02.959 explain away at the trial because it's dad drove him 0:21:02.960 --> 0:21:04.639 out there, so this is sort of maybe dad just 0:21:04.640 --> 0:21:07.640 doing that again. But it's clear that dad, I think 0:21:07.680 --> 0:21:09.479 didn't know because when you get stopped that second time, 0:21:09.480 --> 0:21:10.959 he's talking about how there was like, you know, this 0:21:10.960 --> 0:21:12.840 this crime at this school. I'm like, you would never 0:21:12.840 --> 0:21:14.000 bring that up. If you knew, you would just sort 0:21:14.000 --> 0:21:15.560 of not even say the kid went to WSU. You 0:21:15.720 --> 0:21:17.359 just move along. You try to keep that to yourself. 0:21:17.400 --> 0:21:19.080 But the dad's like, oh, we're coming from WSU and 0:21:19.119 --> 0:21:20.959 there was this, you know, sort of big shooting there 0:21:21.000 --> 0:21:23.280 the other day, not the crime that his son allegedly committed, 0:21:23.320 --> 0:21:25.919 but there was another incident right around the holiday. So 0:21:26.160 --> 0:21:27.800 it's just sort of the dad just seem to be 0:21:27.880 --> 0:21:29.680 completely in the dark. And I mean, and they also 0:21:29.720 --> 0:21:31.639 got home very quickly. They made that trip, like I 0:21:31.640 --> 0:21:33.439 think they stopped one night maybe, and then they were 0:21:33.480 --> 0:21:35.280 on the road. I mean, because they leave the thirteenth 0:21:35.280 --> 0:21:37.280
