Robert Linares was 33 when he was last seen in Los Angeles on December 11, 1993. On that day he called his sister and said he wanted to go to the hospital because he felt like he was going crazy; that phone call was the last confirmed contact. He has not been seen or heard from since.

Linares is described as a Hispanic male, 6 feet tall, 150 pounds, with black hair. Authorities have not developed leads that explain his disappearance, and his information remains in missing persons databases.

If anyone remembers seeing Robert or has information about where he might have gone after that December 11 call, please share what you know.
