Summary based on the NamUs case record (MP55843) and 6 other sources
Apolino Contreras, aged 51, was last seen on March 9, 1998, at a care facility in Los Angeles, California, where he had been living. Contreras had the mental capacity of a two-year-old child and had been placed in the facility after being found wandering in Camarillo, California, in August 1997. Although he knew his name, he was unable to provide other identifying information, and efforts to locate his family had been unsuccessful at the time of his disappearance.

Contreras was last seen by the nursing staff around 2:15 p.m. that day. He was wearing a beige sweater, a maroon and white shirt, blue khaki pants, and orange sneakers. He also had a plastic ID bracelet with his name and address. Due to his mental condition, there is concern that he may have wandered off and been unable to find his way back. Despite extensive searches, there have been no leads, and he remains missing.

Authorities have speculated that he might have ended up in another care facility or hospital. However, despite these possibilities, no concrete evidence has surfaced to explain his disappearance.

Last Seen: Mar 9, 1998
