Olsen was last seen at approximately 2:25 a.m. on January 20, 2007, at Bar One, a nightclub located near the 900 block of West Lincoln Highway and Anne Glidden Road in DeKalb, Illinois. He was intoxicated at the time and making phone calls in an attempt to secure a ride home to Maple Park, Illinois. His cell phone lost power around that time, and he has not been seen or heard from since. Olsen had arrived at the nightclub with friends and remained there until closing, though his friends had left earlier. At the time of his disappearance, Olsen was living with his parents, who were on vacation in Florida. Upon their return on January 24, they reported him missing. Both of Olsen’s vehicles were left at home, and there has been no activity on his bank accounts since he went missing. He also left behind a young daughter.
