Manuel Alvarez, 76, was last seen on February 2, 2018, in San Leandro, California. Before he vanished he had traveled to Costa Rica to investigate the fraudulent sale of his properties by unknown individuals. While in Costa Rica authorities discovered his passport had been used fraudulently, which added another layer of mystery to his movements before he disappeared.

Manuel is described as a Hispanic male with gray hair, about 5 feet tall and 160 pounds. Despite efforts to trace him there have been no significant leads and the case remains open. Authorities are asking anyone with information to come forward.

Did anyone in San Leandro or Costa Rica have contact with Manuel around February 2018 or notice his passport being used?
