Killer who stabbed 4 Idaho students to death still at large

The four University of Idaho students who were stabbed to death near campus last weekend were more than just college students and crime victims. Ethan Chapin was a triplet who spent his last day dressed up and dancing with his siblings at a sorority event. Xana Kernodle was funny and driven, and decorated her high school graduation cap with a quote about changing lives. Madison Mogen and Kaylee Goncalves had grown up together, as much sisters as they were best friends. Both women were looking forward to making big moves next year. Now Ethan Chapin's family is finding solace in the legacy of memories he left behind.
