The family and friends of one of the Idaho murder victims, Ethan Chapin, gathered in Mount Vernon, Washington on Monday to remember the slain student.
“We want to thank each and every one of you for being a part of Ethan’s life,” his family wrote in a program for the memorial.
“It is an incredible testimony to his character just how many lives he has touched in his short 20 years. The loss is unimaginable but our family will persevere.”
Chapin, along with Kaylee Goncalves, Madison Mogen and Xana Kernodle, were stabbed to death inside a University of Idaho off-campus home in the early hours of 13 November.
More than one week on from the killings, investigators continue to be baffled by the case, with no arrests made and no suspects identified.
On Sunday, police admitted that they have no idea if the killer is still at large within the community or has fled the area, despite the overwhelming “mess” of evidence they left behind.
