Bryan Kohberger shut down during his initial interview after his arrest in Pennsylvania, law enforcement officials said at a news conference after his sentencing.

“When we spoke to Mr. Kohberger, we kept it pretty surface level to begin with. The idea being: Get him to speak and keep him speaking. It was pretty surface level. And then went we tried to get into things (with) more detail, he decided to end the interview,” Moscow, Idaho, police Cpl. Brett Payne said.

As soon as Idaho detectives started to explain why they were in Pennsylvania speaking to Kohberger, “that’s when he really started to shut down and then they just shut it down,” Idaho State Police Lt. Darren Gilbertson said.

Asked about Kohberger’s demeanor during that time, the Idaho officials described him as calm, relaxed and very similar to how he was in court.
