Lisa Dianne Jameson was 23 when she vanished after finishing an overnight shift on November 4, 1991. She was last seen around 7:15 a.m. in Chandler near McQueen Road and Chandler Boulevard after giving a coworker a ride. At the time she was married and the mother of a two-year-old son.

Lisa was described as a Black female, brown hair and eyes, 5 feet 6 inches, about 122 pounds, with four piercings in each ear. She was last seen wearing a pink shirt, blue jeans and white shoes, with a silver rope necklace and a silver herringbone necklace. All of her personal belongings, including clothing and credit cards, remained at home and there was no bank activity after she disappeared.

On December 3, 1991, her red 1989 Pontiac LeMans was found abandoned in a Phoenix adult bookstore parking lot; a search of the vehicle produced no evidence to explain her disappearance. The family says Lisa had told her mother the day before she vanished that she believed she was pregnant and was worried about telling her husband. Her husband was never charged; two years later he moved to Bolivia and their son was adopted by Lisa’s parents.

Anyone who knew Lisa, saw her car in late 1991, or has information that could help the Gilbert Police Department should contact investigators.
