Ethan Chapin, 20, Xana Kernodle, 20, Madison Mogen, 21, and Kaylee Goncalves, 21, were tragically found stabbed to death on November 13 at their off-campus house in Moscow, Idaho.

At this time, no suspect has been named and no murder weapon has been found, although the attack appears to have been done with a Rambo-style knife.

“It’s strikingly similar to the Ted Bundy attack,” said Matt Hoggatt, a retired criminal investigator. “Bundy had knowledge of the victims in the house, and it was a sort of frenzied attack with extreme violence.”
