The facility is about 20 minutes outside Boise, where Kohberger appeared in court Wednesday to be sentenced to four consecutive life sentences plus 10 years for the fatal stabbings of Kaylee Goncalves, Madison Mogen, Xana Kernodle and Ethan Chapin.

A document released by police following Bryan Kohberger's sentencing has revealed a rare glimpse into how his next-door inmate perceived him.

Despite Kohberger's guilty plea in the Idaho murders, investigators still don't know his motive, who he targeted or where the murder weapon is after he covered his tracks.

Bryan Kohberger was sentenced to life in prison for killing Madison Mogen, Kaylee Goncalves, Xana Kernodle and Ethan Chapin. Will we ever know his motive?

This new information comes from two friends of Kaylee Goncalves who spoke with police in interviews that were just unsealed by the Moscow Police Department.

Alivea Goncalves, the older sister of the late Kaylee Gonclaves, spoke to him during the hearing, as he sat stoically in an orange jumpsuit.
