The remains of a LA millionaire missing since 1981 have finally been identified after more than 40 years, bringing closure to a decades-old cold case. Authorities in Riverside County, California, announced that genetic genealogy and dental records confirmed the remains found near Sugarloaf Mountain belonged to Thelma Gaston, an 80-year-old widow who vanished in June 1981. This breakthrough solves one of the most perplexing missing person cases in Southern California history.
Who Was Thelma Gaston?
Thelma Gaston was a Los Angeles millionaire who built her fortune by buying and selling repossessed properties after losing her husband and son in the 1950s. By 1981, she had amassed an estate worth an estimated $20 million. Friends described her as a private but generous woman who lived alone in her Los Angeles home.

On the day of her disappearance, authorities found a note on her door saying she was going to look for her cat. She never returned. Police quickly suspected foul play, especially after discovering that Lawrence Remsen, a former carpet salesman and recent companion, had tried to sell over $1 million of her property.
The Investigation and Trial
Investigators found Gaston’s Mercedes at Remsen’s apartment, and he fled during the investigation. He was eventually arrested while crossing the border from Mexico into Texas. During his trial, the prosecution alleged that Remsen killed Gaston to gain access to her fortune. He was sentenced to life in prison.
Despite the conviction, Gaston’s remains remained unidentified for decades. The Riverside County Sheriff’s Coroner’s Bureau used advanced forensic techniques, including genetic genealogy, to finally match the remains to Gaston.
