Just over 24 hours after killer Bryan Kohberger confessed to a court that he had fatally stabbed four students in their off-campus Idaho home, a Peacock Original series dives deeper into the case.

The Idaho Student Murders, which premiered Thursday, July 3, 2025, examines the 2022 murders of four coeds who were brutally stabbed to death in their beds. The now-confessed killer, a criminology grad student and teacher’s assistant in neighboring Washington state, is the focus of the feature-length documentary, which explores the real-life horrors that took place in Moscow, Idaho, with never-before-seen footage and interviews with loved ones.

Here’s what to know about The Idaho Student Murders, streaming now on Peacock.

About the Moscow, Idaho murders

On Nov. 22, 2022, then-28-year-old Kohberger — according to the prosecution — drove from his Pullman, Washington apartment to the 1122 King Road address in Moscow before sneaking through the sliding door in the kitchen. Dressed in black and wearing a mask, he headed to a third-story bedroom before fatally stabbing University of Idaho students and friends Madison Mogen and Kaylee Goncalves, both 21.

Prosecutors outlined in the July 2, 2025 court hearing in Boise, Idaho that Kohberger then encountered Xana Kernodle, 21, around the time she accepted a DoorDash delivery. The killer stabbed her to death before also killing her boyfriend, Ethan Chapin, 20.

Two other roommates, who lay afraid in their bedrooms at the time of the murders, survived the unfathomable ordeal.

Kohberger was arrested in his native Pennsylvania one month later, and a motive has never been discerned.

His decision to change his plea from ‘not guilty’ to ‘guilty’ for four counts of first-degree murder and one count of burglary put the brakes on a highly anticipated trial slated for August 2025. The change of heart infuriated families and continues to unfold in the public eye.

A trial could have given insight into why Kohberger committed the seemingly motiveless crimes.

Meanwhile,The Idaho Student Murders gets into the confessed killer’s background and possible mindset.

Family and friends speak out in The Idaho Student Murders

A host of lawyers and experts in the field of criminal justice and true crime populate the one-off documentary, but some close to the case will especially connect audiences to the grisly tale.

Steven Goncalves, the brother of victim Kaylee Goncalves, is just one to detail the moment he heard about his sister’s horrific death.

“There’s no closure,” he reflected in the documentary. “As of now, I don’t really think I’ve begun the grieving or mourning process.”

As previously reported by Oxygen, the Goncalves family members have voiced being “beyond furious” in light of Kohberger’s recent plea deal.

“I don’t think, for the crimes that were committed, that life in prison is even acceptable,” Steven Goncalves said in the documentary, which was filmed before an Ada County judge accepted the guilty plea. “It’s just not a fitting punishment for what happened.”

Four friends who knew the victims, Kaylee McConkey, Ruby Simpson, Leah Sullivan, and Sophia Whitehead, will each give their accounts of the murders that rocked the otherwise idyllic college town.

Whitehead prefaced to producers, “This is the first time that we’ve done this, and we just hope that people can get a better idea of who Maddie, Kaylee, Xana, and Ethan were as people.”

A criminal justice student who attended school when Kohberger worked as a teacher’s assistant will also give her assessment of the killer, as well as one of Kohberger’s former Tinder dates.
