Summary based on the NamUs case record (MP50222) and 3 other sources
Clemmie Mathis, a 27-year-old man, was last seen on April 10, 1987, in Oakland, California. He was last seen by his landlord, who reported that Mathis refused to open the door to discuss matters related to his lease. After this encounter, Mathis disappeared and has not been seen or heard from since. There are very few details available regarding the circumstances of his disappearance, and no further leads have surfaced over the years.

At the time of his disappearance, Mathis was 5'10" tall, weighed approximately 130 pounds, and had black hair and brown eyes. His case remains unsolved, and both the Oakland Police Department and other investigative agencies continue to seek any information that could help locate him or explain his disappearance.

Despite the ongoing investigation, Mathis' whereabouts remain unknown, and his case is classified as a cold case. Authorities encourage anyone with information to come forward.
