Clemmie Mathis was 27 when he was last seen on April 10, 1987, in Oakland, California. His landlord says Mathis refused to open the door to discuss lease matters; after that encounter he vanished and has not been seen or heard from since. At the time he was 5 feet 10 inches, about 130 pounds, with black hair and brown eyes.

Very few details are available about the circumstances of his disappearance and no significant leads have surfaced. The case remains unsolved and is being treated as a cold case; the Oakland Police Department and other agencies are seeking information that might explain where he went or locate him.

If anyone knew Clemmie, lived near him in Oakland in 1987, or has information about that spring, please contact investigators with what you know.
