"Happy Face Killer" Keith Jesperson believes Kohberger's awkwardness and high-profile murder case make him vulnerable, and he's recommending a transfer to Oregon.

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.

The convicted murderer appears gaunt and expressionless in the photo, taken as he begins to serve out multiple life sentences for the murders of four University of Idaho students: Xana Kernodle, 20; Ethan Chapin, 20; Madison Mogen, 21; and Kaylee Goncalves, 21.

Idaho quadruple murderer Bryan Kohberger transitions from county jail to maximum security prison where inmates with life sentences have nothing to lose

Families of the University of Idaho murder victims spoke directly to their children's admitted killer Bryan Kohberger at his sentencing hearing.

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.

She told police that they planned to meet shortly after he stabbed four students, but that they stopped talking because their conversations made her "uncomfortable."

One victim’s aunt urged the killer to call her and answer her questions. Another’s sister demanded to know her sibling’s last words.
