Bryan Kohberger, the former Washington State University criminology PhD student convicted of murdering four University of Idaho students in November 2022, has filed a petition challenging his conviction, according to court documents reviewed by CrimeBytes.
Background
The four victims—Ethan Chapin, Xana Kernodle, Madison Mogen and Kaylee Goncalves—were killed at their off-campus residence in Moscow, Idaho on November 13, 2022. Kohberger was arrested in Pennsylvania several weeks later and ultimately charged with four counts of first-degree murder and one count of burglary. His trial concluded in late 2024 with a guilty verdict, and he received four consecutive life sentences without possibility of parole.
The case drew national attention due to its unusual circumstances—a criminology student accused of committing brutal murders while studying criminal behavior—and the months-long investigation that preceded his arrest.
The Charges
Kohberger's defense team filed the petition in Latah County District Court, raising multiple grounds for appeal. According to court documents, the defense has argued that certain evidentiary rulings during trial were improper and that there may be grounds for a new trial based on newly discovered evidence or trial errors.
The petition comes within the expected timeframe for post-conviction motions in Idaho criminal cases. The defense is represented by a team of attorneys who have been involved in the case since shortly after Kohberger's arrest.
Prosecutors from the Latah County Prosecutor's Office, who secured the original conviction, will have an opportunity to respond to the petition. The state has previously maintained that DNA evidence, cell phone data and witness testimony supported the guilty verdict.
Key Takeaways
- Kohberger was convicted in 2024 of killing four University of Idaho students in November 2022
- He received four consecutive life sentences without possibility of parole
- Defense attorneys have filed a petition challenging the conviction on multiple grounds
- The petition raises issues regarding evidentiary rulings and potential trial errors
- Prosecutors will have an opportunity to respond before any judicial ruling
What's Next
The Latah County District Court will review the petition and determine whether to grant Kohberger's request for relief. If the district court denies the petition, defense attorneys could appeal to the Idaho Supreme Court. The appellate process could take months or longer, given the complexity of the case and the volume of trial records involved.
No timeline has been set for rulings on either the petition itself or potential subsequent appeals.
