Amanda Rivera was 14 when she was last seen on October 5, 1990. She had been dropped off near a friend’s house on Nobel Street in Spring Valley, California; earlier reports named La Mesa as her place of origin but her last confirmed sighting was in Spring Valley.

At the time she disappeared Amanda stood 5 feet tall and weighed about 110–115 pounds, with brown hair and brown eyes. She was wearing black shorts, royal blue sweatpants and black Vans shoes. Distinguishing marks included a scar on her right hand and a wart on her right index finger. Her case is classified as endangered missing and remains open with the La Mesa Police Department and other agencies; age-progressed photos have been produced.

There have been no significant developments reported and investigators describe evidence as limited. If anyone remembers Amanda, her movements on October 5, 1990, or has information that could help, please contact law enforcement.
