In court in America, Bryan Kohberger, 30, has pleaded guilty to the murder of students Ethan Chapin, Xana Kernodle, Maddie Mogen, and Kaylee Goncalves, who have become known as the Idaho Four. This follows a plea deal to save him from the death penalty.
Here, thriller writer James Patterson and investigative journalist Vicky Ward delve into the crime that shocked America and the mind of the weird individual who carried it out.
‘Chief, we’ve got a bad situation.’ James Fry, chief of police for the small town of Moscow in the north-western state of Idaho, picks up the call informing him of a mass homicide: four murders at a student lodging house.
It’s Sunday, and Fry is about an hour into the four-hour drive back from an overnight stay with friends. He struggles to grasp what Captain Tyson Berrett, the commander of the campus police, is telling him – that four young people, students at the University of Idaho (which the town is home to), have been stabbed to death.
In their bedrooms. In their beds. In a residence that’s part of a large cluster of student housing right on the edge of the campus. And no one heard a thing.
Who in God’s name could have done this? Fry wonders. And will there be more killings? Because somewhere out there in his quiet, law-abiding community, a place where nothing ever happens, a maniacal murderer is on the loose. He floors the accelerator to get back to Moscow at top speed.
There, Captain Berrett is outside 1122 King Road, a house that is famous on campus as Party Central. Just a few weeks into the autumn term of 2022, its occupants have made a name for themselves for hosting the best and most frequent parties at UI. With its sliding doors, perfect for stargazing, it’s a place where people want to come, relax, have a drink, have fun.
It was blonde, vivacious Maddie Mogen who took over the King Road lease and has pulled together a great group of girls to live there – Dylan Mortensen, Xana Kernodle, Bethany Funke, Kaylee Goncalves and herself. They mark their coming together there with a group photograph which Maddie gleefully posts on public forums.
She doesn’t think of any risks associated with exposing themselves in that way. Why would she? The more followers you have, the better for the career in marketing she is planning when she graduates. Nor does she think twice about plastering her initials on the window of her room for anyone to see from outside and placing her signature pink cowboy boots on the sill.
Neighbours are used to seeing Maddie sitting at her dressing table as she takes her time putting on her face. Foundation. Then blush. Eye shadow, mascara or fake lashes. She uses a curling iron to style her long blonde hair. Anyone can see right into her room’s pink interior and discover the minutiae of her life as a ‘cutesy’ girl who likes order. Even her quilt is pink.
She has a boyfriend named Jake who visits at weekends and sits on the bed while Maddie and the other girls model clothes for Instagram and TikTok. Kaylee, one of her friends, often pops in from next door. They are obviously close as they pore over their phones, comparing social media posts, taking photos and videos of each other. They’re having the time of their life.
They’re so immersed in their phones and their cosiness that they never think to look outside. They don’t see anyone out there, staring in.
It’s the early hours of Sunday, November 11 and everyone has been out partying the Saturday night away in clubs, pubs and fraternity houses. At 1.56am Kaylee and Maddie head back home to King Road and chat in the living room. Dylan is in her room, wasted. Bethany is in her room, asleep. Shortly after, Xana and her boyfriend Ethan Chapin return home.
Kaylee and Maddie chat on the couch a little longer and then go upstairs and collapse on Maddie’s bed. Murphy, Kaylee’s goldendoodle, a cross between a golden retriever and a poodle, is in Kaylee’s room. She often leaves him there when she’s out.
At 4.17am, Dylan is in her bed, drifting in and out of sleep. The walls of her bedroom are so paper-thin that earlier she could hear almost everything Maddie and Kaylee and Ethan and Xana were saying as they chatted in the living room. Next thing she hears is stomping as they go up the stairs. She can dimly hear music from one of their bedrooms.
But then everything turns surreal. Not sure whether she’s dreaming or awake, she thinks she hears Kaylee frantically say, ‘There’s someone here’ just moments after going up the stairs. Huh? That doesn’t seem right. And yet it also does, because so many people come and go in the house. She gets up and opens her door a crack. Nothing.
She thought she could hear Xana moving around, doubtless getting a food delivery like she always did after a big night out. And anyway it wasn’t unusual for people to pop in and out of 1122 King Road even at 4am. It was a party house. And people knew to come in through the sliding doors by the kitchen. The lock was broken and you just had to lift the mechanism up and the door released.
Dylan goes back to bed. But then she hears someone crying. Is it Xana? She gets up again and opens her door a fraction of an inch. She hears a male voice say: ‘It’s okay. I’m going to help you.’ There’s a thud. And Murphy starts to bark. Dylan shuts her door again. Is she going crazy? Now there’s silence again.
She opens the door a third time. That’s when she sees what she calls ‘the firefighter.’ He’s got bushy eyebrows; he’s wearing a mask. He’s holding a firefighting object, a bit like a vacuum. Or that’s what she thought he must be, since he wore a mask and was clad head to toe in black.
Was there a fire? Where was the smoke? She was confused. He was walking toward the back sliding doors. They make eye contact for a split second. She shuts her door and looks around for her Taser. The battery is dead.
She tries calling Bethany downstairs. Nothing. But then, thank God, Bethany phones her back. Dylan tells her she thinks she saw someone. In black. Masked. Their call lasts less than a minute. Dylan then calls Xana. No reply. She calls Kaylee. Nothing.
She calls Bethany again. They speak for 41 seconds. Dylan is breathing heavily. She’s terrified. Has she gone crazy? Is she hallucinating? Bethany phones Xana. She also gets no answer. Dylan tries Maddie. Nothing. Bethany phones Ethan. Nothing.
Bethany tells Dylan to come to her room. ‘Run!’ she says, and Dylan does just that. The two friends cling to one another until, exhausted and terrified, they pass out. When they wake around 8am they tell each other they must have been hallucinating.
A couple of hours later, Dylan texts Maddie: ‘R u up?’ There’s no reply, but that’s not abnormal. Dylan dozes off again. Over an hour later, she rouses and also texts Kaylee: ‘R u up?’ Nothing. Now she’s starting to panic again. Perhaps it wasn’t a dream after all. It’s all coming back to her – the man, his bulging blue eyes that caught hers. His thick, dark eyebrows. The mask.
Just before midday, she phones her friend Emily, who is at her apartment in the building next to 1122. ‘Can you come over? Something weird happened last night. I don’t really know if I was dreaming or not, but I think there was a man here, and I’m really scared. Can you come check out the house?’
Emily laughs. Dylan can get really, really drunk. This is not the first time she’s heard a story like this from her. ‘Ha-ha. Should I bring my pepper spray?’ she asks. But her boyfriend, Hunter Johnson, has a sixth sense that something is wrong and is ahead of her as they race next door.
He makes his way up the steps and enters the house, passing Dylan and Bethany, who are barefoot, hands over their mouths, crying. He goes up the stairs and heads to the passage that will take him to Xana’s room. He sees her door is cracked open a few inches. Unusual. Xana never sleeps with the door open.
He looks in and sees Xana lying on the floor as if she’d fallen backward into the room.
Ethan is motionless in the bed behind her, facing toward the wall. There are rivers of blood. He turns around, goes downstairs, and says as calmly as he can to Dylan and Bethany: ‘Call 911. And stay outside.’
He then goes back up the stairs and heads to the kitchen, where he opens a drawer and takes out a kitchen knife. He’s terrified as he waits for the cops in the living room. He says nothing to the others, trying to protect them from both the sight and the reality. But he already knows the horrific truth: Xana and Ethan are dead.
Hunter doesn’t know if Kaylee and Maddie are even in the house, but he fears the worst.
The devil has been at 1122 King Road.
Shortly after, the first police officer to arrive is Mitch Nunes, just 22 years old and only a year into the job. He is expecting a routine situation, probably a student who’s over-imbibed, and is preparing himself to administer CPR. He asks Hunter Johnson, who is still gripping the kitchen knife, to show him the unconscious person.
Johnson takes Nunes upstairs and shows him Xana and Ethan. Nunes takes their pulses. They are dead, clearly the victims of a brutal stabbing. In addition to other wounds, Xana’s fingers are almost severed, suggesting she put up a fight. Ethan looks as if he died while asleep, stabbed in the buttocks and the neck.
Nunes takes out his gun as he checks the rest of the house for the perpetrator. There’s no sign of anyone. Whoever did this must have fled. On the top floor, he finds a dog, a goldendoodle, in one room. In the other, Maddie’s room, he sees two young women, Kaylee and Maddie, lying in Maddie’s bed. Also stabbed to death.
Most were stabbed with a large knife, with just one blow the lethal one in each case. The ferocity is terrifying. A coroner later conjectures that it had to be ‘somebody who was pretty angry’.
Four young people are dead and in the most brutal fashion. But why? On scene now is campus chief of police Berrett. He knows not just from his years of experience but from common sense that the probability of some random stranger knifing four people to death in their bedrooms is almost nil.
There’s a connection somewhere between whoever did this and at least one of the victims. There always is. And it is Emily who finds the link, speculating about Maddie in her part-time job, waitressing at the Mad Greek, a 40-seat restaurant with a vegan-friendly menu. Maddie can make as much as $80 per shift, which covers the fuel for her car, her Ulta credit card for beauty products and the trendy clothes she likes so much.
She wipes down a table and turns to get fresh cutlery to seat new customers. Then she notices him. Unusual-looking. Intense bulging eyes. Thin, almost emaciated. And pale, almost ghost white. He’s raising his hand. He wants her attention. She smooths her skirt and walks over with a smile.
He orders a vegan pizza to go. He’s staring at her intently. Maddie is used to male attention, but this time it feels uncomfortable. ‘I’m Bryan,’ he says. ‘What’s your name?’
Maddie hesitates, then tells him. Why wouldn’t she? Everyone here knows it.
She hands him the bill and, as he pays, he asks, ‘Would you like to go out sometime?’
This is an easy one, Maddie thinks. The idea of going out with this strange-looking guy is surreal. Maddie is anything but easy, even for guys she likes. And she doesn’t know or like this one.
She flicks back her hair. ‘Uh, no,’ she says. She smiles, laughs a bit. It’s a nervous habit she has, especially with guys she turns down. She doesn’t mean anything rude by it.
But this guy looks at her strangely, like he doesn’t believe what he’s hearing. He gets up slowly, still staring at her, and walks out.
Maddie shakes her head and goes about her business. She doesn’t see the guy walk to his car, a white Hyundai Elantra, sit in the driver’s seat, and type her name into his phone.
Her Instagram, with the photos of her past and present, is there for all to see. Maddie in a bikini. Maddie with her room-mates. Maddie and her friends posing in skimpy clothes before a night out.
He presses ‘Like’ once, twice, three times. And then he looks and ‘likes’ some more.
Six months earlier, in the town of Pullman – just over the state border in Washington and 10 miles from Moscow – Chief Gary Jenkins, head of the Police Department, looks at his list of questions and then at the internship candidate he’s zooming with.
The name of the guy staring back at him on the screen is Bryan Kohberger. Jenkins has no idea where he’s from or where he’s situated for their online meeting. He certainly has no idea that just last month Kohberger purchased a Ka-Bar knife, sheath, and sharpener on Amazon for unknown purposes.
What Chief Jenkins does know is that Kohberger, 27, is an incoming graduate student and teaching assistant in the well-regarded criminology department at Washington State University – WSU or ‘Wazzu’, as it’s called – which is in Pullman. Jenkins can see the guy is hyper-focused, but not much else stands out about him, good or bad.
But there’s something anti-social about him that makes Jenkins wary. He gives the internship to someone else, and he doesn’t think much about the guy after that. Barely remembers his name, even.
Kohberger was, in fact, contacting him from Pennsylvania, where he grew up, a troubled teenager, brushes with the police, alienated from his family. He’s diagnosed as Asperger’s; he also dabbles in heroin, with needle scars peppering his arms. Above all, he’s lonely and full of rage that girls want nothing to do with him.
At DeSales University, where he’s studying criminal psychology, there’s something so spooky about him they call him ‘the Ghost’. He shows a particular interest in killers, particularly the serial kind.
And of the greatest fascination for him is the study of Elliot Rodger, a 22-year-old Californian from a wealthy family who in 2014 expressed his fury at still being a virgin by going on a gun rampage and murdering seven people. He declares it his revenge on all the girls who rejected him since he hit puberty. ‘I hate you all. I desired you so much but you looked down upon me as an inferior man.’
He kept a journal outlining his sexual and social frustrations and his various coping mechanisms: video games, late-night drives, trips to the gun range, buying lottery tickets, attempting a new life in Santa Barbara. But none of it gave him sex or girls or the friends he so craved.
Rodger wrote a 137-page manifesto he titled ‘My Twisted World’ and emailed it to his therapist, who sent it to his mother, who received it minutes before her son began his killing spree, at the end of which he shot himself dead.
As the psychology students at DeSales learn about Rodger, they don’t realise that one among them, Kohberger, exhibits every single one of his symptoms. They don’t know about the complaints he makes in private messages about life on ‘Broke Bachelor Mountain’. They don’t know that he too is a virgin who hates women.
Like Rodger, he copes with loneliness by immersing himself in video games, by going for solitary night drives, by visiting the gun range. And, like Rodger, he goes to local bars and tries to pick up women.
He thinks women must surely notice him, spot his looks, his intelligence, and want him.
They don’t. So, after a few drinks, Bryan pushes his way into unwanted conversations with both female bartenders and female customers. He even asks for their addresses.
Women start complaining to the manager about the creepy guy with the bulging eyes.
The hurt festers inside him even as he completes his degree. He’s doing so well that one of his professors recommends him for a PhD in criminal justice at Washington State University. He decides on one last try to get his life on track. He packs up his gear, his new knife included, gets in his car and drives to the other side of America, to the Pacific Northwest.
There, at Washington State, the famed criminology and criminal justice graduate programme has attracted an international elite bunch of seven women and four men, who are pursuing master’s or PhD degrees. At a meet-and-greet, Kohberger stands out. He’s painfully thin. His eyes move too quickly, and the bags under them are dark and too prominent for someone his age.
He never takes off his jacket, even in the August heat, keeping his forearms covered in public to hide the telltale track marks of his past heroin addiction. It’s all part of his plan to start fresh. Become the man he dreams of being. He makes a beeline for the senior faculty members, pumping their hands and working the room. ‘I’m Bryan,’ he says, ‘and I’m excited to be here.’
As he sits in class, Kohberger reflects on incels – that is, involuntary celibates, members of a movement of frustrated men, all virgins, that sprang up in the wake of Elliot Rodger’s mass murder and suicide. The idea behind it is that one day the incels will succeed in overthrowing the Beckys, Stacys and Chads who have managed to make them feel so small and rejected. The group is increasingly associated with violence.
Bryan looks around the class. These women could all be considered Beckys, defined by incels as feminists who dye their hair, post stupid opinions and insist on being the dominant ones in relationships. They need to be put in their place. By contrast, Stacys are stereotypically nubile, used to male attention, prolific on social media, and date hunky, rich Chads.
Bryan gives his presentation to the group, going first, which is what he likes to do. Then the Becky next to him starts hers. He leans in closely, paying attention. As soon as she’s done, he goes on the offensive. He fires questions at her to show how smart he is and how dumb she is.
She’s getting annoyed. The other women are visibly annoyed. Bryan isn’t bothered.
He is bothered, though, not long after when he’s sitting in the class of Dr Hillary Mellinger. She is an advocate for immigrant women and girls who are fleeing men perpetrating gender-based violence by knocking them around. Incels might dismiss her as just another Becky.
Bryan isn’t paying much attention. It’s the end of a long day and he’s tired. But Dr Mellinger suddenly turns to him and puts him on the spot with a question about immigration that he hasn’t prepared for. A member of the class recalls: ‘He was trying to say something, but he couldn’t find the words. He didn’t move, didn’t speak.’ Dr. Mellinger looks shocked at his lack of response. The Beckys all stare at him.
Fortunately for Kohberger, this happens in the final few minutes of class. He’s the last to leave the room, so no one sees his face as he heads to his car, red-hot angry and ashamed. The stuttering, awkward guy, the real self he’d tried to leave behind in Pennsylvania, just appeared like a jack-in-the-box.
It’s a reasonable speculation that not long after, Bryan goes for an evening drive in the dark. He drives when he can’t sleep. When his head is full of demons mocking him. He keeps asking himself: Why am I like this? But he finds no answer.
To make matters worse, he has no one to share his hopelessness with, even if he could find the words to express his feelings. The others on the course don’t seem to want to hang out with him. He knows the class gathers on weekends for a beer but no one has invited him to join them.
In his car, he crosses the state border into Idaho, parks in the centre of Moscow and heads to a place he’s read about online: the Mad Greek. He walks inside and instantly notices the blonde waitress. Her name is Maddie. With her long hair and sphinx-like blue eyes, she would definitely be marked as a Stacy by the incels, the epitome of the women who turn down men like him.
She comes over to ask what he’d like. He knows what he’d like. Her. God help her if she turns him down.
