Kaylee Goncalves, one of four students University of Idaho students who was brutally murdered on Nov. 13, told others that she "may have had a stalker" before she was killed, but authorities have not been able to verify that information, police said on Wednesday. 

"We obtained information through some of our interviews that Kaylee had made some comments about a stalker. So that's where that came from," Moscow Police Captain Roger Lanier told reporters on Wednesday. 

"We have followed up looking at specific time frames and specific areas of town. So far, we have not been able to corroborate it, but we're not done looking into that piece of information."

Police previously said they've received "hundreds of pieces of information" related to Goncalves potentially being stalked.

Goncalves and Madison Mogen returned to their three-story off-campus residence around 1:45 a.m. on Nov. 13 after going to a local bar and stopping at a food truck. 

Goncalves made multiple calls to her ex-boyfriend between 2:00 and 3:00 a.m., but they went unanswered. Police say that her ex-boyfriend is not a suspect.

No suspect has been identified and police have not located a murder weapon, but Jim Clemente, a retired FBI supervisory special agent and criminal behavioral analysis expert, previously told WHD News Digital that the killer likely knew the victims or was a stalker familiar with their habits.

"Going into an occupied dwelling with six people in … different rooms in the middle of the night is an extremely high-risk crime, unless he knows one or more of the people," Clemente told WHD News Digital. 

"So, that is my first thought on it: this offender did not just randomly choose this location, that he targeted one or more of the people in there. Now, that could be because he has a relationship or a past relationship with one or more of them, or it could be that he's been stalking one or more of them."
