Law enforcement officers are asking for your help in solving the mysterious disappearance of a Hawthorne woman.

Nita Mayo vanished one month ago and a $10,000 reward is now offered for her safe return.

Mayo's four children are frantically trying to find their mother after the 63-year-old woman vanished August 8, during a shopping trip to Sonora, California.

Mayo's was found, but there was no trace of her. Now, her family is pleading for your help in finding her.

In an effort to attract national attention to the baffling case, the Carole Sund-Carrington Foundation and Equusearch, are offering $5,000 each for Mayo's safe return.

Because the area where her car was found is near a resort area, Mayo's family is concerned that a tourist may have seen her, or witnessed and incident, but then left the area and is unaware that Mayo is missing.

Her family hopes that with more publicity about their mother, someone will come forward with information that will bring her home.

Anyone with information in this case is urged to call the sheriffs department at 800-228-3592.

Authorities say there's no evidence that Mayo disappeared on her own, or that she was suicidal. They've processed her car, where they found her purse, but say they are still looking for clues about her disappearance.
