Bryan Kohberger, who pleaded guilty in July 2025 to the fatal stabbing of four University of Idaho students in November 2022, has filed a petition seeking to challenge his conviction and guilty plea. Kohberger’s move to seek post-conviction relief was filed on July 27 in Ada County District Court, Idaho, where he will represent himself. In the petition, Kohberger asserts his innocence and claims that his confession was coerced.
The four students—Kaylee Goncalves, 21; Madison “Maddie” Mogen, 21; Xana Kernodle, 20; and Ethan Chapin, 20—were found stabbed to death in their off-campus Moscow, Idaho, residence. According to law enforcement and former FBI agent Ed Jacobson, the attacks occurred during the early morning of November 13, 2022. Goncalves and Mogen were discovered together on the third floor, while Kernodle and Chapin were found in the second-floor bedroom. Kernodle sustained over 50 stab wounds, indicating a struggle, and was observed to have defensive injuries.
The investigation led authorities to arrest Kohberger on December 30, 2022, at his family home in Pennsylvania. Evidence included DNA linking Kohberger to a Ka-Bar knife sheath found near the victims, as well as cell phone data and surveillance footage identifying a vehicle connected to the crime scene during the time of the murders. Kohberger’s phone was inactive during the attacks and reconnected to cellular towers afterward. Digital forensics also revealed a post-incident “thumbs-up” selfie taken by Kohberger.
Kohberger, a criminology graduate student at Washington State University, had previously exhibited troubling behavior including reported conflicts with faculty and intimidation of classmates, particularly female students. He was removed from his teaching assistant position in December 2022 following disputes with university personnel. Friends have noted Kohberger’s past struggles with heroin addiction and emotional difficulties, including suicidal ideation during his teenage years.
The victim families have expressed mixed emotions since Kohberger’s guilty plea, which averted a trial and eliminated the possibility of the death penalty. On the day of sentencing, some family members confronted Kohberger with pointed statements, while others retreated from the courtroom. Despite the conviction, family members and the public have expressed lingering questions about motive, as Kohberger never provided an explanation.
In response to Kohberger’s recent petition, Idaho Attorney General Raul Labrador extended condolences to the victims’ families. The Goncalves family publicly criticized the filing, likening Kohberger to a persistent nuisance. They also highlighted their desire for a trial to fully address the case, stating their readiness to proceed if the plea is withdrawn.
The petition seeks to reopen the case on grounds that may include alleged ineffective legal counsel and constitutional errors, though Kohberger has not disclosed new evidence to support his claims of innocence. The forthcoming legal process will determine whether the guilty plea can be overturned and the case reexamined. Meanwhile, the case continues to attract significant public interest, fueled in part by multiple documentary projects examining the events and aftermath of the murders.
