Sergio Noriega was 18 when he was last seen at his Los Angeles home on July 27, 1990. He is described as a Hispanic male, 5 feet 3 inches tall, about 145 pounds, with black hair and black eyes. Very few details are available about the circumstances of his disappearance and there is no information about his movements after that day.

The case remains open with the Los Angeles Police Department, but investigators report no significant developments over the years. There are no known fingerprints or dental records available for Sergio, which investigators say makes identification more difficult if remains were ever located.

Does anyone have memories or information about Sergio, his neighborhood, or where he might have been after July 27, 1990?
