Bryan Kohberger's Parents Subpoenaed By PA Grand Jury: Report

MONROE COUNTY, PA — The parents of Bryan Kohberger, who is accused of killing four University of Idaho students in their off-campus house in November, have been subpoenaed to testify before a grand jury in Monroe County, according to a report by WPVI-TV citing a source familiar with the case.

Kohberger, 28, was indicted by an Idaho grand jury on murder charges last week. He was arrested at his parents' Pennsylvania home in December nearly seven weeks after authorities found students Ethan Chapin, Madison Mogen, Xana Kernodle, and Kaylee GonCalves stabbed to death in their Moscow, Idaho, home.

Kohberger's parents were subpoenaed in the county where they live. According to WPVI, his mother has already testified before the panel and his father is expected to testify Thursday.

Evidence collected could be shared with prosecutors in Idaho, WPVI reported.

Kohberger is charged with four counts of first-degree murder and burglary in connection with the stabbing deaths of the four students. Autopsies showed the students were likely asleep when they were attacked on Nov. 13. Some had defensive wounds and each was stabbed multiple times.

Kohberger stood silent in Idaho court Monday before a judge entered a not-guilty plea on his behalf.

A motive for the killings is still unclear; however, a slew of details, including descriptions of events on the night of the murders from surviving roommates of the victims, were revealed after Kohberger arrived in Idaho on Jan. 4, prompting the probable cause affidavit to be unsealed.

In their search of Kohberger's apartment in Washington state — where he was a doctoral student at Washington State University — investigators seized stained bedding, strands of what looked like hair, and a single glove, but no weapon, according to documents released in January.

According to a search warrant that allowed Pennsylvania law enforcement officers to search Kohberger's parents' Pennsylvania home—where he was arrested—officials swabbed Kohberger's DNA and seized a silver flashlight, four "medical-style gloves," a white Arizona Jean Co. T-shirt, a black Champion sweatshirt, a pair of black-and-white size 13 Nike shoes, black Under Armour socks, black Under Armour shorts and black Under Armour boxers.

The search warrant was posted in full by WNEP.
