On November 13th, 2022, four college students were brutally murdered inside their home in Moscow, Idaho. What followed was one of the most chilling manhunts in modern American history. And the suspect would shock the world. It was just after 4:00 a.m. on November 13th, 2022. The kind of crisp early morning on a quiet street where the world feels suspended between night and day, just before the first light of dawn. Six University of Idaho students were asleep inside a three-story rental home on King Road. A typical student house with mismatched furniture and the lingering scent of late night study sessions. The normaly of it all, that quiet expectation of another day, made what was to come even more horrifying. The house was an unsuspecting vessel holding so much life. By sunrise, four of those lives would be tragically extinguished. The victims were Kaylee Goncalves, Madison Mogan, Zanna Kernodal, and Ethan Chapen. Young, vibrant, and full of life. They were the very essence of a college town defined by laughter, friendships, and future plans. They had spent the night with friends, a simple, carefree evening that was a thousand miles away from the nightmare that was about to unfold. They were unaware that a predator had been watching them for weeks, that their lives were the final pieces in a dark, twisted puzzle being assembled in a mind driven by a terrifying obsession. That night, a figure moved through the shadows with a chilling precision. Investigators believe he entered quietly. No smashed windows, no broken locks. The killer came prepared, armed with a combat style knife, gliding through the darkness with a haunting confidence that betrayed months of meticulous planning. He was not a whirlwind of chaos, but a surgical instrument of death, moving with a purpose we couldn't yet comprehend. His target was clear, his motive still a ghost. Within minutes, four lives were taken in what detectives would later call a surgical, controlled act of violence. There were no screams a neighbor could hear, no chaotic fight, just silence. The two surviving roommates, who had been on the first floor, were unharmed. It was a chilling detail, one that amplified the sheer control of the perpetrator. He had made a choice not to harm them or perhaps simply hadn't known they were there. This added to the chilling, calculated nature of the crime. The house itself was strangely quiet, almost frozen in time, a silent witness to the unimaginable. >> 919 on location of your emergency. >> Hi, something is happening. Something's happening in our house. We don't know what. >> What is the address of the emergency? >> 112. [Applause] >> 11:55 a.m. on November 13th, 2022, a young woman calls 911. Distraught, she passes the phone to another person who reveals a crucial detail in the case. >> Tell me exactly what's going on. >> Um, one of our one of the roommates has passed out and she was drunk last night. He's not waking up. >> Okay. >> Oh, and they saw some man in their house last night. >> According to recently released text messages, one of the roommates reported seeing a man dressed entirely in black wearing a mask. A little after 4:00 a.m., the two surviving roommates grew frightened and even sent messages to the other four housemates. Eventually, though, they decided to stay in their rooms and went back to sleep. By the time they placed the 911 call, they only knew that their roommates weren't responding, but had no idea why. The dispatcher kept pressing for details, not about what happened earlier at 4:00 a.m., but about the current situation and who might need immediate help. The following exchange is intense, unedited, and may be disturbing to some listeners. >> Okay. I need to know what's going on right now. If someone is passed out, can you find that out? >> Y'all come. Come on. Let me double check. She's passed out. What's wrong? She's not waking up. [Music] >> Okay, one moment. I'm getting started that way. >> Moments later, a man's voice can be heard urgently telling everyone to get out of the house. He's then handed the phone. >> Hello. >> Okay, I need someone to stop passing the phone around because I've talked to four different people. >> Hey, sorry. They just gave me the phone. >> Is she breathing? >> Hello. >> Is she breathing? >> No. >> Roughly 3 minutes into the call, a Moscow police officer arrives at the house and assumes control of the situation. Moscow Police Corporal Brett Payne was the first officer to arrive at the scene. Where she at? Where she at? >> Nobody's allowed to leave for now. Okay. Um, just stay here for me, please. And is this your address? >> Yes. >> What's that address? >> 1122 King Road. >> What do you remember seeing what started? >> I remember um I was in my room and I was trying to go to bed and I heard Kaye who um >> for investigators the pressure was suffocating. Hundreds of tips poured in, each one a thread we had to pull. Thousands of internet detectives flooded forums, convinced they had cracked the case. But leads were scarce and the world demanded answers. Every day without an arrest amplified the panic. The FBI, state police, and local officers formed a joint task force. A small army chasing a ghost. We had to tune out the noise and trust our training. The students, who had once felt invincible, were now living in a state of constant fear. The college campus, a place of vibrant energy, fell into an eerie silence. The >> world is a darker place without them. But the light of their light of their love and memories will always guide us all. Maddie has truly been a blessing in our lives. Watching her grow and mature to the amazing woman she's become, it's truly priceless in our hearts. >> Sienna, you will not be forgotten. You have impacted so many lives and have given people so much love. I hope I can make you proud and try to leave an impact on this world and on people like you did. If you knew Ethan, he was never angry about anything. Um, and you would never get upset. You couldn't upset him ever. We're just heartbroken. We know it. It's just going to take time for everybody to heal. if that's possible. I I just pray that it is. >> Every press conference was a battle against the rising tide of fear and frustration. >> The facts of the case that we know right now, we know that these homicides occurred in the early morning hours of Sunday, November 13th. Around noon, Moscow officers received a call of an unconscious person. Officers discovered the bodies of Ethan Chapman, Xanakodal, Madison Mogan, and Kaye Gonavs inside the residence on King Road. The four were stabbed with a knife, but no weapon has been located at this time. There was no sign of forced entry into the residence. Investigators are continuing to collect evidence at the scene. Investigators are working to develop a timeline to relevant events. Autopsies are taking place today on all the victims so we can continue to gather evidence and solve the crime. We knew the public was hurting, but we had to be patient. Then came the first clue, a white Hyundai Elantre. Surveillance footage showed the car passing by the King Roadhouse multiple times before the murders and again minutes afterward. It was a phantom vehicle that left a trail of digital breadcrumbs. Investigators traced every white elantra in the region, hundreds of them. A painstaking process of sifting through thousands of records. October 14th, 2022, on the Washington State University campus, police stopped Coberger for red light and improper stop violation. He calmly explained he was unfamiliar with the area and walked away with just a warning, but he gave his phone number to the officer. Good on a Honda. I don't see Pennsylvania registration like at all. Okay, let's see. Expires November 22nd or 2022. Okay. And >> yeah, one of those is actually >> Yeah. Okay, that looks good. I'll hand that back to you. I'm just going to go check your info. I'll try to find that uh RCW, the law for you, and I'll be right back. >> Thank you. All right. But here's the twist. This stop later helped investigators link his car to surveillance near the crime scene. Again on December 15th, 2022, Indiana, according to official reports, Brian Cobberger was stopped for following a vehicle too closely. He was driving a white Hyundai Elantre already identified as a key veracle of interest in the investigation. off the street lights. I stopped you when you were driving by me there. We were looking clos 10 mph. [Applause] [Music] It's a long haul. Guys scared of airplanes. >> Stop ended with verbal warnings. This all happened while he was driving cross country just days before his arrest. No tickets were issued. When investigators get a phone number, everything changes. It's like unlocking another piece of the puzzle. You don't see the full picture yet, but you get closer. In Cobberger's case, one detail stood out. Between 2:27 a.m. and 4:48 a.m., the exact window when four students were murdered. His phone went completely silent. No calls, no messages, no connection to any tower. Sometimes it's not the evidence you find. It's the silence that speaks the loudest. The cell phone data was a silent witness. The pings showed a clear pattern of reconnaissance. He would drive by the house, sometimes in the middle of the night, sometimes in the early morning hours. A horrifying ritual of a predator circling its prey. The real turning point came when investigators found a knife sheath near one victim's body. On it was a microscopic trace of DNA. To confirm their suspicion, agents collected trash from Brian's parents' home in Pennsylvania. A match. The DNA on the knife sheath and Brian's family profile linked perfectly. It was a silent confession he didn't know he'd left behind. Investigators examined a latent shoe print found just outside the door of the victim's bedroom on the second floor. The print revealed a diamond waffle pattern, a hallmark reminiscent of Vans style souls. This discovery helped confirm the suspect's path through the home. The discovery of the knife sheath was a breakthrough, but the trace DNA on it was a fragile piece of evidence. The DNA testing was a race against time, a final sprint in a marathon investigation. So, investigators had DNA from the crime scene and they took the DNA and they ran it through the National Crime Database and there were no hits, no matches. But the DNA was still useful because you could eliminate potential suspects. And there were a lot of them. Not only ones that law enforcement was looking at, but a whole bunch that people online, all those true crime [ __ ] that are out there were looking at as well. A white Hyundai Elantre was spotted speeding near the crime scene that night. Investigators pulled surveillance footage from nearby cameras and tracked the car's movements, eventually capturing its license plate. one registered just 10 miles away belonging to Brian Coberger, a 28-year-old PhD criminology student at Washington State University. This was our first real lead, a single thread connecting a faceless crime to a potential suspect. His device had pinged near the victim's house 12 different times before the murders, and finally, DNA on a knife sheath left at the scene matched Coberger's profile, sealing his identification. On December 30th, 2022, a SWAT team surrounded Brian's parents' home. At 1:00 a.m., they quietly entered. There were no sirens, no yelling. Brian didn't resist. He simply stood there, calm, almost detached, as though this was another case study in his research. He was taken into custody without a struggle. His demeanor as cold and controlled as the crime he was accused of. There was no theatrical reveal, no dramatic breakdown, just a silent, chilling acceptance. [Music] >> Police department search warrant, come to the door. >> When they first spotted him inside the house, he was wearing latex gloves and going through his own trash bags, carefully picking stuff out and putting it into separate Ziploc style bags. Investigators suspected he was doing this to avoid leaving any of his DNA in the household trash, knowing police might be monitoring it. The meticulousness of this act was a direct reflection of his academic pursuits. He wasn't just a killer. He was a student of crime, a scholar whose theories were now being put into deadly practice. The intel revealed a methodical mind, someone who was not only planning a crime, but also planning his escape. He was a man who believed in his own intellectual superiority. A man who saw this as the ultimate academic challenge and he was arrogant enough to think he could win. He once posted a survey on Reddit asking convicted murderers to describe their thoughts, emotions, and actions during killings. The line between academic curiosity and morbid fascination had long been blurred. He wasn't just studying criminals. He was rehearsing. >> Good afternoon. I'm Colonel Roberty Vanchic, commissioner of the Pennsylvania State Safe Police. While I monitor the investigation into the horrific murders of the University of Idaho students, I did not imagine the investigation would lead to the Commonwealth of Pennsylvania. My heart goes out to the families of the victims, their friends, the community of Moscow, and the University of Idaho. No words can heal the pain associated with the loss of a child. Their young lives were ended far too soon. In law enforcement, we understand the best thing we can do for victims and their families is to follow every lead, collect every piece of evidence, and bring those responsible to justice. I am proud of the members of the Pennsylvania State Police were able to help in this investigation. The cooperative relationship between our local, state, and federal partners stands the test of time. The officers, troopers, and federal agents work together tirelessly, putting in long, difficult hours. Communication and cooperation are imperative to success and to ensure the integrity of the case remains maintained. The culmination of that cooperation ultimately led to take the suspect into custody and afforded the families some sense of peace they deserve. >> The arrest shook the nation. A criminology PhD student accused of one of the most horrifying crimes in recent memory, Brian Coberger was sentenced after overwhelming evidence tied him to the murders. A knife sheath left at the scene carried his DNA with a match probability of one in five octillion. His phone records showed 12 late night trips near the victim's house, and on the night of the killings, the phone went dark for 2 hours before reconnecting nearby. Surveillance cameras captured his white Hyundai Elentra circling the area during that window. Investigators also traced Amazon records showing he purchased a KBAR knife, sheath, and sharpener. None of us have experienced the loss these victims have in the unspeakable way that they have. And therefore, none of us can nor should we question the way in which they have handled their loss. Whether that be in private morning, removed as far as possible from this media circus or in front of a camera demanding retribution with the loudest megaphone. And therefore, I will not attempt to speak about him further other than to simply sentence him so that he is forever removed from civilized society. and accordingly based upon his conduct and based upon the record before this court recognizing the standards that govern this court's sentencing decisions as set forth in state v2ill I hereby sentence Mr. Hberger as follows. On count one, burglary, 10 years fixed, zero zero years indeterminant. I also impose a fine of $50,000. Count two, first-degree murder of Madison Mogan. I sentenced the defendant to a fixed term of life imprisonment without the possibility of parole, a fine of $50,000, and a civil penalty of $5,000 payable to the family of the victim. On count three for first-degree murder of Kaylee Gonzalez, I sentence the defendant to a fixed term of life imprisonment without the possibility of parole, a fine of $50,000, and a civil penalty of $5,000 payable to the victim of the family or to the family of the victim, pardon me. On count four for the first-degree murder of Xanna Kernodal, I sentenced the defendant to a fixed term of life imprisonment without the possibility of parole, a fine of $50,000, and a civil penalty of $5,000 payable to the family of the victim. On count five of the first-degree murder of Ethan Chapen, I sentenced the defendant to a fixed term of life imprisonment without the possibility of parole, a fine of $50,000, and a civil penalty of $5,000 payable to the family of the victim. The sentences on counts 1 2 3 4 and five shall run consecutively to one another. I ref I I remand the defendant to the custody of the ID state board of corrections for to be imprisoned in an appropriate facility and execution of the sentence where he will remain until he dies. The case of Brian Christopher Coberger is a stark reminder that the darkest corners of the human psyche are often hidden in plain sight behind a veneer of normaly waiting for the right moment to emerge. And that more than anything is the part that will haunt me forever. But for the victim's families, the nightmare doesn't end. And yet, one question haunts everyone. Why? Why them? Why this way? >> We are now certain who committed these unspeakable acts of evil. But we don't know. And we what we may never know is why. >> Investigators believe Brian's motive lies somewhere between obsession, resentment, and intellectual arrogance. Brian Coberger studied killers. He wanted to understand them, but in the end, he became one of them. It's a story about a scholar who became the subject of his own study. A man whose intellectual arrogance led him down a path of self-destruction. It's a chilling reminder that the line between knowledge and madness can be incredibly thin. He understood the rules of the game, the psychological profiles, the forensic techniques, and the weaknesses in the system. He was not a phantom, after all. He was flesh and blood. A man who left a trail. And a detective's job is to follow that trail no matter where it leads. In this case, it led us to a place we never expected. Into the dark and twisted mind of a scholar who became the very monster he was studying. And that more than anything else is what truly haunts me. [Music] M [Music] I close my eyes and I count to 10. I hope when they open I see you again it's true. Just want to be with you. The times we're together I hold in my heart this could last forever. I knew from the start I knew just want to be with you and I'll be by your side and hold your hand when the waves get high. There's nothing that I won't do for you. [Music] for you. You You are
