Slain University of Idaho student Kaylee Goncalves’ had “no idea” that murder suspect Bryan Kohberger was allegedly stalking her and her roommates at their off-campus home before the brutal killings, her sister said.

Alivea Goncalves said she was shocked to learn that Kohberger had allegedly visited her 21-year-old sister’s off-campus home in Moscow, Idaho at least a dozen times before the murders on Nov. 13.

“We had no idea. She had no idea. I had no idea that true evil was genuinely watching them,” Alivea told NewsNation.

Alivea said that she had spoken with Kaylee every day before her sister was killed along with her roommates Madison Mogen, 21, Xana Kernodle, 20, and Kernodle’s boyfriend Ethan Chapin, 20.

“That’s been the hardest part of this is to sit back and look at the totality of it. When my sister was FaceTiming me about a new egg bites recipe, he was planning his next visit to the home,” she said.

“That’s really difficult not to wish that you had done more and wish that you had known more. But, it’s just the first step. A lot more evidence will come out,” Alivea told the news outlet.

She said she believes Kohberger may have been watching the probe play out online.

“A lot of that comes from the fact that he had visited the home so many times before, late at night and early hours. He’s presented this pattern of behavior,” Alivea said.

“He went back to the home the morning of, before police had been called, I think to see if his circus, so to say, had started to unfold. I think he would not have been able to refrain from engaging with the online communities, the theories, the conspiracies, and everything in between,” she told NewsNation.

She said her family is setting up a foundation in Kaylee’s memory.

“We still have such a long road ahead of us. The relief that we all felt having a suspect in custody was, I can’t even describe it, like the weight of the world was lifted from our shoulders,” Alivea told the outlet.

Kohberger, 28, who was a PhD student in criminology at Washington State University at the time of the crime, made his first court appearance in Moscow on Thursday and is being held at the Latah County Jail.
