Martin Valencia Renteria, 27, went missing on July 20, 1990, from Santa Ana, California. He and his brother, Jose Renteria, were last seen when they left for Los Angeles in a 1978 silver Chrysler. Both brothers have been missing since that date, and neither has been heard from since. At the time of his disappearance, Martin was 5'4" to 5'9" tall, weighed between 140 to 190 pounds, and had black hair. His disappearance is considered suspicious, though there has been no confirmed foul play.

Despite investigations and appeals for information, both Martin and his brother remain missing, and authorities continue to seek any leads regarding their whereabouts. The case remains open, and the Santa Ana Police Department urges anyone with information to come forward.
