Earlier Tuesday, Kohberger was spotted for the first time since his arrest stepping out of a prisoner transport van outside the courthouse in advance of his extradition hearing.
Kohberger, 28, wore a red jail-issue jumpsuit and had his hands shackled in front of him, as two law enforcement officials escorted him to the Monroe County Courthouse at about 10:45 a.m.
He remained stone-faced as reporters pelted him with questions, "Why did you do it?"
At one point the accused mass murderer wore a haunting expression and looked directly at the crowd of photographers and reporters.
The Washington State University Ph.D. student was arrested early Friday for allegedly stabbing to death Kaylee Goncalves, Ethan Chapin, Xana Kernodle and Madison Mogen in the early morning hours of Nov. 13 in an off-campus rental home.

Kohberger, who was studying at WSU's Department of Criminal Justice and Criminology, was transported from the Monroe County Correctional Facility – about 7 miles away – to the courthouse for a 3:30 p.m. extradition hearing.
His attorney, Jason LaBar, previously said he will not fight extradition and will voluntarily return to Moscow, Idaho, where he faces four counts of first-degree murder and one count of felony burglary for the quadruple homicide.
His parents and two sisters are expected to be in court.
