William Billy Trimbach, 26, was found shot to death with a 9mm firearm on February 14, 1993, his first wedding anniversary. His body was discovered along a frontage road off Interstate 76 near Wiggins, Colorado, having been dragged from a vehicle. At the time he lived in Stoneham with his wife, Cindy, their infant daughter and Cindy’s nine-year-old son. He worked as a mechanic and reportedly was trying to earn money for his wife’s medical treatments for AIDS.

Investigators focused quickly on Cindy. She reported him missing the morning his body was found but gave inconsistent accounts. Her Chevrolet Suburban had been in the remote area where his body was discovered, and small amounts of Trimbach’s blood were found in the backseat. A large life insurance policy with a forged signature and the disappearance of Billy’s 9mm handgun further raised suspicion. Cindy moved to Butte, Montana after the funeral and later died of AIDS-related complications in 1994; she was never charged.

The probe has remained open but hampered by scant direct evidence and unreliable witnesses, some reportedly methamphetamine users. Theories have ranged from a drug-related intimidation killing or accidental death to Cindy hiring someone for the insurance money; another person later named a person of interest as possibly involved. No arrests have been announced. Does anyone with information about Billy’s movements in February 1993 or who knew the family then want to come forward?
