Idaho State Police have released over 2,300 pages of investigation records related to the quadruple homicide of four University of Idaho students. The records include photos of Bryan Kohberger’s Ka-Bar knife sheath and details of DNA testing that connected him to the crime scene. The evidence, which includes forensic samples and crime scene photos, was a key part of the investigation that led to Kohberger’s arrest and conviction for the murders of Madison Mogen, Kaylee Goncalves, Xana Kernodle, and Ethan Chapin.
Forensic technicians tested the sheath for DNA evidence, ultimately recovering a sample on the snap. The sample later turned into a tip developed by investigative genetic genealogists and ultimately led police to Kohberger’s parents’ home in Albrightsville, Pennsylvania, where he was arrested on Dec. 30, 2022. Kohberger pleaded guilty in July and was sentenced to four consecutive prison terms of life without parole, plus another 10 years, for the murders of the four students.
Other evidence released includes handwritten notes from investigators, photos of nail clippings from the victims that were tested for DNA evidence, and samples from Kohberger’s Hyundai Elantra that were tested at the crime lab. According to the investigators’ notes, the victims left a sliding door open on the night of the attack for Goncalves’ dog, who was found unharmed in her bed. Goncalves and Mogen were both killed in Mogen’s bedroom.
Many of the records had to do with crime lab work, including DNA testing, fingerprint analysis and other measures early in the investigation. The release of these records highlights the meticulous process employed by law enforcement to solve the case, providing insight into the methods used to identify and apprehend the suspect. As the investigation continues, officials remain focused on ensuring justice for the victims and their families.
