Martiniano Herrera-Pastora, 24 when he vanished, was last seen at West Anaheim Medical Center in Anaheim, California, on January 21, 2023. The Anaheim Police Department logged the case as 23-11698 and it is also in NamUs as MP157402. He is also known as Martin Herrera.

Herrera-Pastora is described as a Hispanic or Latino male, about 5 feet 8 inches and 180–200 pounds, with brown hair that may have been shaved and blue eyes. Reports differ on what he was wearing when last seen: one account says a hospital gown, another lists a red long-sleeved shirt, blue jeans, cowboy boots and a belt buckle. There is no publicly noted distinctive physical feature, and no information about transportation or documents he may have had.

The investigation remains open. Did anyone in Anaheim see Martiniano around January 21, 2023, or have information about his movements that day?
