In a pivotal decision shaping the high-profile Idaho college killings case, Judge Steven Hippler rejected defense efforts to exclude DNA evidence and digital records from Bryan Kohberger’s murder trial. Prosecutors argue the forensic data directly ties Kohberger to the 2022 stabbing deaths of four University of Idaho students.
Authorities utilized investigative genetic genealogy to link DNA from a knife sheath at the crime scene to Kohberger.
The Court finds suppression is not warranted on any of these issues,Hippler stated, emphasizing constitutional protocols were followed during evidence collection.
Key case details:
- Victims: Ethan Chapin, Madison Mogen, Xana Kernodle, and Kaylee Goncalves
- Charges: Four counts of first-degree murder, burglary
- Trial start: August 2024
Investigators combined digital warrants for Kohberger's Apple/Google accounts with trash DNA retrieved from his parents’ Pennsylvania home. The genetic match probability—1 in 5.37 octillion—reportedly solidified prosecutors’ case.
Defense attorneys claimed overreach in evidence collection methods, but the judge ruled police acted appropriately given concerns about evidence destruction. Surveillance logs detail Kohberger’s suspicious late-night activities before arrest, including handling bags with rubber gloves.
With the death penalty looming, this ruling clears prosecutors to present their most critical forensic arguments. Legal analysts suggest the investigative genetic genealogy precedent could influence future criminal proceedings nationwide.
