Genetic genealogy combines DNA analysis with genealogical research, such as family tree tracing. In this case, investigators discovered male DNA on the button snap of a leather knife sheath found at the crime scene.
FBI investigators uploaded the DNA profile to public genealogy databases, leading them to Kohberger. Prosecutors argue it provides a strong link between Kohberger and the crime scene.
Cell Phone Tracking Data and Surveillance Videos
On April 17, 2024, Kohberger’s defense filed a motion indicating they would present a cell phone tower and radio frequency expert to support his alibi that he was driving west of Moscow at the time of the murders.
Meanwhile, lead investigator Cpl. Brett Payne testified that law enforcement officials collected thousands of hours of surveillance footage to locate a white Hyundai Elantra associated with the suspect.
The footage is stored on multiple thumb drives, though Payne acknowledged there is no centralized inventory of the videos.
Payne further testified that none of the videos show the Elantra traveling south from Moscow toward Pullman, Washington, in the early hours following the murders.
