• Authorities looking for more leads in fatal stabbing of Idaho college students.
  • Two other roommates unharmed could be ‘key’ to investigation, authorities say.
  • Victim’s father said his daughter likely fought with killer during stabbing: ‘She’s a tough kid.’

The murder investigation into four University of Idaho students believed to have been stabbed to death while sleeping in their beds has left residents rattled and authorities trying to unravel a mystery that’s getting increasing attention across the country.

Sunday’s crime has reverberated through the college town of Moscow, a city of about 26,000 people near the Idaho-Washington State border. Moscow hasn’t had a murder in about five years. 

The victims were stabbed to death in their beds and likely were asleep, Latah County Coroner Cathy Mabbutt told NewsNation. Mabbutt would later tell CNN that she saw “lots of blood on the wall” when she arrived at the scene.

“It has to be somebody pretty angry in order to stab four people to death,” Mabbutt told the cable news channel. The victims were stabbed in the chest and upper body, she said.

The coroner added that stab wounds on the hands of at least one victim appear to be defensive wounds and that there were no signs of sexual assault.

“We’re looking for additional tips and leads,” said Aaron Snell, a spokesman for the Idaho State Police told CNN on Friday.  “We believe that releasing information about the locations of the victims throughout the night might generate some information that we can follow up on.”

Snell contends that the incident was “targeted” but would not say why as now state and federal authorities are on the hunt for who killed the students.

Here’s what we know so far:

Who are the victims?

The four students have been identified as Ethan Chapin, 20, of Conway, Washington; Madison Mogen, 21, of Coeur d’Alene, Idaho; Xana Kernodle, 20, of Avondale, Arizona; and Kaylee Goncalves, 21, of Rathdrum, Idaho. Each was either in a fraternity or a sorority and Kernodle and Gonclaves were roommates.

Jeffrey Kernodle, the distraught father of Xana Kernodle, told Phoenix TV station KTVK/KPHO that he spoke to his daughter by phone before she was killed.

“I think midnight was the last time we heard from her, and she was fine,” Jeffrey Kernoldle told the station. The victim’s father said that he doesn’t understand why his daughter and her roommates were killed.
