Shannon Rose Lloyd was a 23‑year‑old white woman who was found dead on the morning of May 21, 1987, in the bedroom of the rental home she shared with a roommate in the 11900 block of Donna Lane, Garden Grove. An autopsy determined she had been sexually assaulted and died by strangulation. Her roommate was the one to find her, and there was no indication anyone else was in the home at that time.

Investigators processed the scene, conducted interviews, and recovered forensic evidence that yielded a male DNA profile. That profile did not match CODIS entries at the time and the case went cold. In 2003 DNA from Shannon’s case was linked to the 1989 killing of 27‑year‑old Renee Cuevas. Advances in forensic genealogy led investigators in 2021 to identify Reuben J. Smith died by suicide in July 1999 and thus was never charged in these murders.

Anyone with information about Shannon Lloyd or Smith’s activities in Orange County during the 1980s is asked to come forward.
