Mary Darlene Evans, known as Dolly, was 43 when she disappeared from Vacaville, California on October 1, 1986. That evening she had dinner with her husband and left to visit a friend but never arrived. A few days later her silver Pontiac Parisienne was located abandoned on Greenfield Avenue in Vallejo; her purse was missing and there were no signs of a struggle or forensic evidence in or around the car.

Evans was 5 feet 2 inches and about 140 pounds. She was wearing a red dress, high heels and several pieces of jewelry including a black ring with small diamonds. Family and friends have been ruled out as suspects and searches and investigations have yet to produce solid leads.

If anyone knew Mary’s movements that night or remembers seeing her car on Greenfield Avenue, please share what you know.
