Authorities seized several items from the Washington apartment of University of Idaho killings suspect Bryan Kohberger on the day he was arrested, including a computer tower, possible hair strands, and a pillow with a "reddish/brown stain," newly-released records show.
According to search warrant documents released on Wednesday by Washington's Whitman County Superior Court and viewed by Insider, investigators also seized a "nitrite type" black glove, a Fire TV stick, a possible animal hair strand, receipts, mattress covers, and the dust container from a vacuum from Kohberger's apartment.
Kohberger, a 28-year-old Ph.D. student in the criminal justice program at Washington State University, was charged on December 30 with four counts of first-degree murder and one count of felony burglary in connection to the November 13 killings in Moscow, Idaho.
Four college students and friends — Kaylee Goncalves, 21, Madison Mogen, 21, Xana Kernodle, 20, and Kernodle's boyfriend, Ethan Chapin, 20 — were stabbed to death in their beds in an off-campus rental home following a night out, authorities have said.
The unsealed search warrant spells out how Kohberger first came under suspicion by the police, when a white Hyundai Elantra was seen in the area of the house around the time of the murders.
They tracked that car down to Kohberger, and through further investigation, got his phone number. On the night of the murders, his cellphone pings show him leaving his apartment after 2 a.m. and then the phone either losing service, being turned on airplane mode, or turned off. Investigators suggested in the warrant that he may have purposely disconnected his phone, so it didn't register as being close to the house. But they asked for older records connected to the number which show him visiting the area of the home of the murders on at least 12 occasions prior to November 13, all in the late evening to early morning hours.
Investigators say in the documents that they believe the murders happened sometime after 4 a.m., and that Kohberger's phone started pinging again at 4:48 a.m., south of Moscow. Kohberger proceeded to travel south on Highway 95, then west to Uniontown, Idaho, before eventually turning north back to Pullman, where he returned to residence around 5:30 a.m.
