Officials in Moscow, Idaho, will hold a press conference on Wednesday afternoon related to the ongoing investigation into the horrific murders of four local university students. 

University of Idaho students Ethan Chapin, 20, Kaylee Goncalves, 21, Xana Kernodle, 20, and 21-year-old Madison Mogen were stabbed several times and killed in the early morning hours of November 13, officials have said. Police have not identified any suspects. 

Moscow police received a call shortly before noon on Nov. 13 for a report of an "unconscious person" at the King Road home. Several other people had gathered at the crime scene by the time police arrived, officials said.

The surviving roommates had also gone out that night, but returned to the house by 1 a.m., police said. 

Police have said they have cleared both surviving roommates, the person who drove Gonsalves and Mogen from the food truck, and a person who was spotted on surveillance video standing behind the women at the food truck.

Officials said late Thursday that investigators had received information that Goncalves could have had a stalker. Investigators "looked extensively" into those reports, and "have pursued hundreds of pieces of information" related to the stalker tip. As of Tuesday, they had been unable to confirm the information or identify a stalker.
