On August 2, 1974, 18-year-old Carol Louise Valenzuela left her Camas home after an argument with her husband and hitchhiked to Vancouver to visit a friend. She was seen at a welfare office that morning and told to return at 1 p.m. to pick up food stamps; she never came back. Two days later her husband reported her missing. Carol was a mother to 10-month-old twins.

In October 1974 skeletal remains near Dole Valley, about 14 miles northeast of Vancouver, were identified by dental records as Carol’s. Another set of remains found roughly 100 feet away remained unidentified until 2015, when they were confirmed as 17-year-old Martha Morrison; investigators determined both deaths were homicides.

Over the years several persons of interest were examined, and attention eventually centered on Clark County Parks Department employee Warren Leslie Forrest, who had access to remote areas and a violent history. A 1974 survivor identified Forrest after escaping an attack, and he was convicted in the murder of Christa Blake. DNA advances linked Forrest to evidence in Morrison’s case; in 2019 blood on an air pistol of his matched Morrison, and in 2023 he was convicted for Morrison’s murder.

Does anyone have knowledge of Carol’s movements that August day or information about people who were in the Camas–Vancouver area then?
