MESA COUNTY, Colo. (KKCO) - A man convicted of murder in Fort Collins has been transferred to Mesa County to face charges in a second murder.

Douglas Thames is now registered in the Mesa County Inmate Inquiry system.

According to his mother, Sandra Gifford, Thames was brought to Mesa County for processing Tuesday morning.

Gifford says she is frustrated because it's been several days since she's heard from Thames, who is currently serving a life sentence for the murder of a Fort Collins women in Canyon City.

His mother says she called the Fremont Correctional Facility looking for answers when she hadn't heard from him. "They told me he had been moved at 8 o'clock yesterday morning, so I called back up here to Mesa County, to find out why they had told me he wasn't here, and they told me he hadn't been processed yet."

Gifford says she hasn't been told when she can expect to speak to him again. Says Gifford, "I feel terrible. I don't know if my son's okay, I worry about his safety. I don't know what's going on. I worry about him."

Prosecutors with the Mesa County District Attorney's office say Thames' DNA connects him to the 1994 murder of Jacie Taylor in Palisade.

Thames, 39, is already serving a life sentence in the Fremont Correctional Facility in Canyon City for the murder of Susan Doll in 1989. He has lost several appeals. His mother says he's innocent, and blames mistakes by the investigators. She also says he does not have a public defender in that case.

Investigators say DNA recently exonerated Robert Dewey, who spent a total of 18 years behind bars for Taylor's rape and murder in Palisade.

According to Gifford, Thames is set to make his first Mesa County court appearance later this month.
