For nearly four decades, the murder of Rhonda Marie Fisher sat unsolved inside a Douglas County, Colorado case file that had grown to thousands of pages. Then, in December 2025, investigators cracked it — using DNA extracted from the interior surfaces of two paper bags placed over Fisher's hands at the scene in 1987.
Fisher was thirty years old when she was found dead in rural Douglas County in 1987. From the first hours of the investigation, responding officers made a decision that would prove consequential nearly four decades later: they placed paper bags over her hands before she was removed from the scene, a standard forensic precaution intended to preserve trace evidence on the skin's surface. That routine step would ultimately break the case.
The death generated thousands of pages of accumulated material over the years — reports, witness statements, forensic analyses, and administrative memos that grew as the investigation aged without resolution. Detectives worked the case through the late 1980s and 1990s but were never able to identify a suspect. Without a match, the file gradually transitioned from active to cold, remaining officially open but effectively dormant.
