Sherry Boyd, 44, was found floating in Prospect Lake in Colorado Springs on October 16, 1987. Ten years earlier she had survived a violent assault that left her crippled and dependent on a wheelchair; despite that, she was described as independent and a familiar presence in her neighborhood.

An autopsy determined the cause of death was asphyxiation and the death was ruled a homicide. Evidence indicated she had been strangled before her body was placed in the lake. How a woman confined to a wheelchair came to be in the water remains a central, unanswered question in the investigation.

The case remains open and no arrests or suspects have been publicly identified. Anyone with information about Sherry Boyd or her movements in the weeks before October 16, 1987 is asked to come forward.
