William E. Billy Trimbach, 26, was found shot to death with a 9mm handgun on February 13, 1993, discarded along a desolate frontage road off Interstate 76 near Wiggins in Morgan County, Colorado. Evidence indicated his body had been dragged from a vehicle. At the time he was living in northeastern Weld County with his wife, Cindy, their baby daughter, and a 9-year-old stepson; the family had moved to Colorado from Nevada about a year earlier. Trimbach worked as a mechanic and reportedly was covering mounting medical bills for his wife, who was battling AIDS.

Investigators quickly focused on Cindy Trimbach after she reported him missing the morning his body was found.

The investigation has been complicated by unreliable testimony and drug involvement among people connected to the case. Detectives developed a theory that Billy may have been killed during an attempted intimidation and that Cindy may have arranged the killing for insurance money and helped dispose of the body, but no one has ever been formally charged and the case remains unsolved. Does anyone with memories of the Trimbach family or the Wiggins area in early 1993 have information that could help the investigation?
