Deborah Diane Owens, 24 and a mother of two, was last seen at her Oroville, California, home on November 19, 1978. Her husband, Marvin Gail Owens, said he was the last to see her that morning and reported her missing two days later. Deborah had a history of brief absences but always kept in touch with her daughters, a point that delayed alarm when contact stopped.

Investigators long treated Marvin as a person of interest. In 1989 police searching his residence recovered Deborah’s wedding rings, which she was known never to remove, and a pair of roller skates Marvin said she had when she disappeared. Marvin later moved to Ogallala, Nebraska. In February 2015 he was arrested and charged with Deborah’s murder; in March 2015 he pleaded guilty to voluntary manslaughter and admitted strangling her during an argument. He told investigators he buried her in a shallow grave in the Oroville Wildlife Area but could not pinpoint the spot. Multiple searches have not recovered her remains, and Deborah is presumed a victim of foul play.

Did anyone in Oroville know Deborah’s routines, friends, or places she visited in 1978 that might narrow search areas or provide further detail about her last day?
