On a September morning in 2003, 74-year-old Lois V. Butler was found mortally wounded in the front yard of her home on Linda Lane in Adams County, Colorado. A neighbor initially thought she’d suffered a heart attack, but paramedics determined Butler had been shot multiple times in the back. At least seven shots from a small-caliber weapon were fired; bullets also struck the side of her house and a neighboring residence.

Butler was a breast cancer survivor and was planning an upcoming vacation with her husband, Tom Butler, a retired Denver Police Department officer. Investigators examined whether the shooting was connected to his former career but found no evidence to support that theory. A man seen near the Butler home around the time was described as a Black male in his mid-20s, medium build, about 5 feet 8 inches to 6 feet tall.

Possible motives considered included a random act, a thrill kill, or mistaken identity, but detectives had no solid leads and the case grew cold. Did anyone in the community have contact with Lois or notice someone matching that description around Linda Lane that September morning?
