Diana Lynn Ramel disappeared in 1980 while married to Gerald Frank Stanley, a man with a documented history of lethal violence against his spouses. Stanley was previously convicted in the 1975 killing of his second wife, Kathleen Stanley, and was later convicted for the 1980 sniper-style murder of his fourth wife, Cindy Rogers Stanley.

In 2011, while on death row at San Quentin, Stanley told a reporter he had killed Diana Lynn and said he buried her near a creek bed in Tehama County, near Manton, California. Searches, including use of cadaver dogs by the Tehama County District Attorney and the California Department of Justice, have not located remains. Investigators cite Stanley’s inconsistent cooperation and the large, rugged search area as obstacles to recovery.

Does anyone have information about Diana Lynn’s last known whereabouts, or recall sightings or knowledge of the Manton-area creek beds referenced in the confession?
