University of Idaho Heightens Security on Campus

University of Idaho students returned to classes following what police described as "a sense of fear in our community." There's also heightened campus security, particularly around sorority and fraternity houses. It comes as the murder investigation of four roommates enters it's third week. Now, similarities are emerging with another unsolved murder case 400 miles away in Salem, Oregon. However, police say "there does not appear to be any evidence to support the cases are related."
