Retired Truck Driver Charged With Murder of Woman Found in Desert Center Nearly 30 Years Ago

On March 30, 1993, the body of Herrera was found in Riverside County, California onramp to a major highway

A retired Texas truck driver was charged in connection with the 1993 cold case murder of a woman whose body was found in Riverside County, the Riverside County District Attorney's office said Friday.

Douglas Thomas was charged in the slaying of Sherri Herrera that occurred nearly 30 years ago.

On March 30, 1993, the body of Herrera was found on the eastbound Hayfield Ramp Road onramp to I-10 in Desert Center.

She was a mother of four from Tulare, California. She was last seen alive a few days before her death, officials said, but were vague on details of her last sighting.

In May 2022, Texas Rangers arrested Thomas in Titus County, Texas, on suspicion of the murder in connection with the crime.

Thomas was identified via DNA that was found at the scene, authorities alleged.

Thomas is a retired truck driver with a 40-plus year career who drove far and wide across the United States.

The DA’s office charged Thomas with murder that was allegedly taking place during rape.
