Bryan Koherberger wasn't only stalking the four University of Idaho students before he brutally murdered them almost three years ago! It turns out he also watched two other female college students while attending Washington State University! According to copies of their interview obtained by People on Tuesday, the two women told the Idaho State Police the former criminology student visited them "daily" at their work. That's how it started, and the situation became increasingly concerning when he began to show up at their homes unexpectedly.
