A month after the gruesome killings of four University of Idaho students in their off-campus home, authorities have yet to name a suspect or locate the murder weapon as hundreds of students take final exams before winter break.The students, Kaylee Goncalves, 21; Madison Mogen, 21; Xana Kernodle, 20; and Kernodle’s boyfriend, Ethan Chapin, 20; were likely asleep when they were each stabbed multiple times in the early morning hours of November 13, authorities have said.Lanier’s remarks come as hundreds of University of Idaho students are taking final exams this week before the fall semester ends and investigators comb through more than 6,000 tips they’ve received in the case.“This is not an indication of a specific elevated risk, but something that we should be vigilant with just in our daily lives,” Lanier noted.“It’s time for us to give those things back that really mean something to those families and hopefully to help with some of their healing,” Moscow Police Chief James Fry said last week in a video statement."
