Jennifer Sue Larsen, 21, disappeared after a summer party in Aurora, Colorado. She was last seen leaving the gathering in the early morning hours of August 10, 1995, and was reported missing on August 13 after her father could not reach her. Her apartment showed no signs of struggle or forced entry, but her red 1994 Toyota coupe was gone.

A week after her disappearance friends found the car abandoned in an apartment complex parking lot about a mile from where she was last seen. The vehicle was unlocked, windows partially down and the keys on the floor mat; residents said it appeared to have been blocking a play area for several days. On October 4, 1995, skeletal remains found in a sunflower field near Strasburg were later identified by dental records as Jennifer’s. Because of the remains’ condition the exact cause of death could not be determined, and authorities ruled the death a homicide.

The Arapahoe County Sheriff’s Office and the Colorado Bureau of Investigation have investigated leads over the years, including a male acquaintance of a friend who had a history of violence against women and others in her social circle, but no arrests have been announced. Does anyone have memories or information about Jennifer, the party she attended, or her last known movements?
