Watch : How Bryan Kohberger’s Mom and Sister Reacted in Court to Idaho Murder Sentencing

Authorities have released chilling details about Bryan Kohberger’s initial police interview.

In Moscow Police Department documents submitted to court in July and obtained by E! News, Corporal Brett Payne—the lead detective in the murder investigation of University of Idaho students Kaylee Goncalves, Madison Mogen, Xana Kernodle and Ethan Chapin—said Kohberger engaged in “small talk” about college sports following his arrest in December 2022.

“Kohberger stated he didn’t follow WSU football much but was a baseball fan,” Payne, who conducted the interview with ISP Detective Sergeant Darren Gilbertson, wrote in his report. “Kohberger then asked if it was OK to engage in small talk like we were, to which we replied it was.”

Kohberger told authorities—who detained him at his parents’ home in Pennsylvania after linking his car to the Idaho crime scene—that he had never been to the Pacific Northwest before moving to Washington State University for his PhD program, but had since formed a deep connection to the area.
