University of Idaho murder victim Kaylee Goncalves' sister Alivea Goncalves described what it was like coming face-to-face with killer Bryan Kohberger at his sentencing hearing. On Wednesday, July 23, Alivea delivered a searing victim impact statement in which she directly addressed Kohberger, 30, at the Ada County Courthouse in Boise, Idaho. In addition to telling Kohberger to "sit up straight when I talk to you," a defiant Alivea informed her sister's killer that Kaylee would've "kicked your f***ing ass" had he not attacked her and best friend Madison Mogen in their sleep.
