As Idaho police and federal law enforcement continue their search to identify a suspect in the killing of four University of Idaho students, community members and local business owners are contributing to memorials in remembrance.

Four University of Idaho students, Ethan Chapin, 20; Xana Kernodle, 20; Madison Mogen, 21; and Kaylee Goncalves, 21, were stabbed to death on early Sunday morning between the hours of 3 a.m. and 4:00 a.m. in a Moscow, Idaho, residence near the college campus. 

As of Friday night, police don't have any suspects in the fatal stabbings, according to a press release from the Moscow Police Department.

According to police, the Latah County coroner believes that the "four victims were likely asleep, some had defensive wounds, and each was stabbed multiple times."
