Richard Birkmayer, 63, was last seen December 1, 2018, in San Bernardino, California. He had been communicating with family while hospitalized, but contact stopped after his release, which prompted concern. He is described as a white male, 5 feet 8 inches tall, about 160 pounds, with brown hair.

He may be in a medical or care facility or could be experiencing homelessness; searches and listings in missing persons databases have not produced a confirmed location. Authorities are asking the public for any information that could help locate him.

Did anyone in the San Bernardino area see Richard or have information about possible facilities where he might be?
