(NewsNation) — The sister of Kaylee Goncalves, one of four University of Idaho students murdered by Bryan Kohberger in 2022, says she needs “the full picture” of what occurred.
Alivea Goncalves spoke with NewsNation senior national correspondent Brian Entin ahead of Kohberger facing the victims’ families at his sentencing Wednesday.
Per the plea agreement, Kohberger does not need to offer any details regarding the murders of Goncalves, Madison Mogen, Xana Kernodle and Ethan Chapin.
Alivea GoncaIves: “I need that full picture”
Goncalves explained her family wasn’t against the possibility of a plea deal, but wanted a full confession from Kohberger.
“I think for me, specifically, and I wish I wasn’t this way, I need that full picture, right? I still just feel like I don’t even understand what the hell happened,” she said.
“None of it makes sense to me, and I can look at these facts, but as far as putting something together in my head that makes sense, it’s really difficult for me to do.”
Goncalves says he has not learned of a motive but doesn’t believe Kohberger has a reason that would “make sense to any of us.”
Kohberger, a former graduate student in criminal justice at Washington State University, faces murder charges for the deaths of Xana Kernodle, Madison Mogen, Kaylee Goncalves and Ethan Chapin, who were killed at an off-campus house near the University of Idaho on Nov. 13, 2022. He had pleaded not guilty.

Bryan Kohberger is a “psychopath”- Alivea Gocalves
“I think that even if he was hooked up to a lie detector and given truth serum, the why would be that he was just desperately trying to feel anything at all because he’s a psychopath and he doesn’t feel human emotions the way we do,” she said.
Notwithstanding her desires to understand why the murders occurred, Goncalves says she hopes Kohberger is never given a chance to explain himself to the public beyond Wednesday.
“I hope that after sentencing, no one ever says his name again, because I think that an individual like he is, any attention is positive. He views it positively.
“It doesn’t matter if someone’s talking poorly or talking positively about him, because attention is what is craved and it feeds into his ego. So for me, I think the best way to, you know, kill an ego is to stop feeding it.”
