Idaho Murders Update: Police Investigating Item Related to Victim's Mail

One of the victims' parents in the Idaho killings said police are investigating something "mail-related" in their ongoing search for the suspect who fatally stabbed four University of Idaho students last month.

The parents of Kaylee Goncalves spoke to Fox News on Sunday about the ongoing investigation and the updates they've received from police. Asked about the last time the parents talked with police, Steve Goncalves, Kaylee's father, told Fox host Lawrence Jones it was last week.

He also said that he and his wife were asked to sign a "waiver form" to allow police to investigate "something that was mail-related." Goncalves did not offer any further details on what police were investigating in regard to the mail.

His remarks come about three weeks after the killings, which occurred at a residence near the university. On November 13, officers with the local Moscow Police Department went to a home at 1122 King Road in response to a report about an unconscious person. The officers found the four dead students, identified as Goncalves, Madison Mogen, Ethan Chapin and Xana Kernodle.

"The Latah County Coroner confirmed the identity of the four murdered individuals and their cause and manner of death as homicide by stabbing," the police said in a statement. "The coroner stated the four victims were likely asleep, some had defensive wounds, and each was stabbed multiple times. There was no sign of sexual assault."

Since the killings, police have not said anything about a suspect or person of interest, and no weapon has been found. However, the police earlier said that they believe a "fixed-blade knife" was used in the crime.

Thomas O'Connor, a former FBI agent, previously told Newsweek that identifying the weapon used could help police track down a suspect. "If they can determine the type of weapon and if it's something that's not a common household appliance, then they have a better chance of tying it back to an individual, which could be a long shot but that's what police work is," O'Connor told Newsweek.

Last week, a former FBI profiler spoke to Newsweek about a possible suspect and said it is likely the person was familiar with the house where the victims were living.

"When you murder four people, you're gonna get in and out pretty quickly, and so in order to do that, and lowering your own risk level, you have to have some knowledge of that place," Mary Ellen O'Toole told Newsweek.

Newsweek has reached out to the Moscow Police Department for comment on Goncalves' remarks.
