Bryan Kohberger allegedly spent Christmas Day 2022 downloading information on more than 20 serial killers while at his family's home in Pennsylvania. According to Heather Barnhart, a SANS Institute Fellow and Senior Director of Forensic Research at Cellebrite who led the prosecution's digital forensics team, the files included information on Danny Rolling, who murdered multiple college students after entering their homes through sliding glass doors and used a KA-BAR knife in the attacks. #BryanKohberger #IdahoMurders #TrueCrime #UniversityOfIdaho #thecrimedesk
