Idaho college murders: Kaylee Goncalves' dad has 'inkling' about victims' 'behavior difference' before attack

Goncalves said he has an 'inkling that there was some behavior difference' among victims

The father of Kaylee Goncalves, one of four University of Idaho students murdered in a home near campus on Nov. 13, told Fox News on Thursday that he has an "inkling" about the victims' behavior.

"I do have some inkling that there was some behavior difference. … When you commit a crime, you [have] different behaviors," Steven Goncalves said on "The Story with Martha MacCallum" when asked whether his daughter may have been the target of the Nov. 13 attack, adding later that he was referring to "behavior of the victims."

He said he asked permission from police "to put any of that out," which they declined because "it would not be beneficial."

The other victims of the attack include Kaylee's best friend, 21-year-old Madison Mogen; Xana Kernodle, 20; and Ethan Chapin, 20. The Latah County coroner said each of the victims were stabbed to death, likely while sleeping, and some had defensive wounds.

Goncalves previously told ABC News that he believes his daughter may have had a stalker. The Moscow Police Department (MPD), which is handling the investigation into the murders with state and federal partners, said it is aware of those reports but is not able to corroborate them.
