A black glove, a stained pillow and receipts from Walmart and Marshalls were among items seized from the apartment of a criminology major accused of fatally stabbing four University of Idaho students, according to court documents released Tuesday.

Among the items investigators took from the Pullman, Washington, apartment of Bryan Kohberger were possible hair strands, a pillow with a “reddish/brown stain,” a computer tower, a “nitrite type” black glove, receipts, mattress covers and an Amazon Fire TV stick, a search warrant unsealed by the Whitman County Superior Court says.

The documents come a week after Kohberger, 28, was charged with four counts of first-degree murder in the deaths of Ethan Chapin, 20, Madison Mogen, 21, Kaylee Goncalves, 21, and Xana Kernodle, 20. The students were found stabbed to death in an off-campus home where most of them lived in Moscow, Idaho, on Nov. 13.
