A mysterious 911 call sent police officers rushing to the street the night the four University of Idaho students were murdered. Police logs from that fateful night show a disturbance in a field outside of the Sigma Chi Fraternity. The Moscow Idaho police daily activity log reveals officers responded to an alcohol offense at 3:01 a.m. That's right around the time cops say the murders were committed. However, police say the incident is unrelated to the murders.
