Peter Theriault, a 51-year-old Army veteran, was last seen on December 2, 1998, in Irvine, California. He lived with his girlfriend, Judy Valot, and failing to show for his usual night shift at a Ford plant prompted concern. Valot at first said he left after an argument; investigators later pointed to inconsistencies in her account and delays in reporting him missing.

Investigators found blood in Theriault’s garage and car and other circumstantial evidence that led them to suspect Valot. Authorities alleged jealousy over an alleged affair as a motive, though no proof of an affair was reported. Theriault’s body was never recovered; searches did not locate him, and it was suspected he might have been buried in the desert between Irvine and Blythe.

Valot was convicted of second-degree murder in 2000; that conviction was overturned and she was retried and convicted again in 2005, receiving a 15 years to life sentence. She has consistently denied involvement and no body or murder weapon has been found. Does anyone have information about Theriault’s last known movements or the search areas between Irvine and Blythe?
