Body language experts analyze Bryan Kohberger's cold demeanor during his Idaho murder sentencing, revealing moments when his emotionless facade cracked during victim impact statements.

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

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.

"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.

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."

Alivea Goncalves delivered a blistering statement to her sister's killer, Bryan Kohberger, during his sentencing hearing on July 23.
