In the early morning hours of February 18, 2017, 29-year-old Kelly Bly Acosta was shot and killed in the parking lot of his Aurora, Colorado, apartment complex on South Crystal Circle. Witnesses say Acosta intervened to stop a man assaulting a woman; the assailant then turned and shot Acosta before fleeing in what witnesses described as a possible white vehicle. First responders arrived around 4:00 a.m.; Acosta was taken to a nearby hospital and later pronounced dead. The Arapahoe County coroner ruled the death a homicide by gunshot wound.

Aurora Police have continued the investigation but no arrests have been announced, and the case has gone cold. Local and federal agencies have offered substantial rewards for information leading to an arrest and conviction. If anyone has information about the shooting, the vehicle, or the person who fled that night, please come forward to help bring justice for Kelly.
