Police in Idaho yet to name suspect in off-campus weekend killing of four college students

Police investigators have yet to identify a suspect in the weekend killing of four college students at their off-campus residence.

Capt. Anthony Dahlinger, of the Moscow, Idaho, police department said Tuesday, when officials gave their most recent update, that investigators were "looking for a suspect," according to news reports.

Police have also said they shared all of the information they possibly can without compromising the investigation.

However, authorities have also said the attack was "targeted" and a "crime of passion."

They also described the crime scene as the "worst they've ever seen." 

The University of Idaho students were left to bleed out after they were stabbed to death on Sunday, according to news reports.

"There was blood everywhere," an official familiar with the investigation told the Daily Mail. "We have investigators who have been on the job for 20, even 30, years, and they say they have never seen anything like this."

Officials said the suspect used a knife or knife-like weapon.

The victims have been identified as Ethan Chapin, 20; Madison Mogen, 21; Xana Kernodle, 20; and Kaylee GonCalves, 21. Social media shows that Chapin and Kernodle appear to have been in a relationship.
