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

"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."
