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

In the days after murdering four University of Idaho students in an off-campus home, Bryan Kohberger’s behavior shifted dramatically and investigators would later find that he had fixated on news coverage of the killings and began paying for items in cash – often wearing gloves – as he avoided the area of the murders.

"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."
