Douglas Thomas

Douglas Thomas, 67, was arrested on May 25, 2022 for the April 1992 murder of Shenda Denise Hayes in Mount Pleasant, Texas.

Hayes’ body was found near a rest area on the Interstate-30 outside of Mount Pleasant. She had been sexually assaulted and strangled with a device made of wire and cord.

A DNA sample from a SAK taken at Hayes’ autopsy was uploaded to CODIS in 2004. It was match to a similar homicide that took place on March 30, 1993 in Desert Center, California. The body of Sherri Herrera was found along the Interstate-10 Highway in the desert between Palm Springs and Arizona. She, too, was sexually assaulted and had been strangled to death with a belt. Both women were engaged in sex work at the time they were murdered.

DNA taken at the scene of Herrera’s murder had been uploaded to CODIS in 2002, and a SNP profile suitable for FGG was developed in September of 2020. There is no information on who performed the FGG investigation. The final confirmation was made after a warrant was issued to take a DNA sample from Thomas for comparison.

Thomas is a retired long-haul truck driver from Waco, Texas. He is currently being held on $2 million bail in Titus County, Texas.

On June 13, 2022, Thomas was also charged in the murder of Herrera, with a special circumstance of committing a murder during a rape. He will first be prosecuted in Texas, and will then be extradited to California.
