DNA could be the key to solving the case of a missing California mother who disappeared on April 29, 1997.

Police in the small city of Petaluma, north of San Francisco, announced this week that new DNA evidence has emerged regarding the disappearance of Jamie Coe, then 38, who was last seen at home following a job interview.

A $2,500 reward has been offered to anyone who can help solve the 24-year-old case. Detectives have not disclosed what type of DNA they collected or how it may help them find Coe, who would be 63 years old today. A police bulletin has been issued with an artist’s sketch of what Coe would look like now.

Coe was not reported missing until three days later when she failed to pick up her children at her father’s house, according to news reports.

Police discovered video evidence that a woman in a Ford Mustang drove up to a local bank ATM and used Coe’s card hours after she had arrived home. However, the images are not clear enough to be useful.

Coe’s 1989 Ford Aerostar was later found abandoned in a field of the famed Napa wine country. Although Coe had friends in Napa, none of them had seen her. It's assumed Coe did not drive the car because she wore either glasses or contact lenses, and both were still at her home.
