Diane Mae Talavera, 37, was reported missing in April 1988 after her boyfriend contacted her mother on April 10, 1988. An official missing person report was filed by her mother 17 days later. Her body was later found in Lake Elsinore, California. Authorities determined her cause of death was strangulation combined with an overdose of amphetamines.

Talavera was one of at least 13 women later linked to William Lester Suff, a white male who became known as the Riverside Prostitute Killer and the Lake Elsinore Killer. Suff targeted women between 1988 and 1991; many victims were involved in sex work or struggled with substance abuse and were found nude or partially clothed after suffering violent deaths. Suff was arrested on January 9, 1992, and was convicted of 13 murders.

Anyone who knew Diane Mae Talavera, her movements in April 1988, or saw her in the Lake Elsinore area is asked to share information that could help document her last days.
