STRUDSBERG, PA – Law enforcement officials seized dark clothing, medical gloves, a flashlight and other items from a Pennsylvania home where they arrested a graduate student accused of stabbing to death four University of Idaho students, according to newly unsealed court documents.

The records were released Tuesday, two months after Pennsylvania State Police arrested Brian Koberger at his parents’ home in eastern Pennsylvania.

Koberger, 28, a former doctoral student at Washington State University, is charged with four counts of first-degree murder and burglary in connection with the stabbing deaths in Moscow, Idaho.

The bodies of Madison Mogen, Kaylee Goncalves, Xana Kernodle and Ethan Chapin were found on November 13, 2022, in a rental home across the street from the University of Idaho campus. The killings shocked the rural Idaho community and nearby Pullman, Wash., where Koberger was a graduate student studying criminology at Washington State University.

Pennsylvania State Police swabbed Koberger’s DNA and seized a silver flashlight, four “medical gloves,” a white Arizona Jean Co. T-shirt, a black Champion sweatshirt, a pair of black and white Nike size 13 sneakers, black Under Armor socks, black Under Armor shorts, and black Under Armor boxers, according to the item inventory.

The meaning of the objects, if any, was not immediately clear.

A roommate who lived in the home where the attack took place told authorities she was awakened early on the morning of Nov. 13, opened her bedroom door, and saw a masked figure dressed in black walking past.

A preliminary hearing in Koberger’s case is scheduled for late June. He has yet to enter a guilty plea.

Additional warrants for Koberger’s arrest in Pennsylvania are expected to be released Wednesday.

During a search of Koberger’s apartment in Washington state, investigators seized stained bed linens, locks of hair and one glove, but no weapons, according to documents released in January.
