Summary based on the NamUs case record (MP1396) and 5 other sources
Anthony Steven Balthazar, a 23-year-old man, was last seen on March 24, 1980, in Santa Cruz, California. He disappeared after wandering away from a mental health facility. At the time, Balthazar was battling schizophrenia, which may have contributed to his sudden departure. Despite investigations, no further trace of him has been found, and his whereabouts remain unknown.

Balthazar is described as a Hispanic male, 5'8" tall, weighing around 140 pounds, with brown hair and hazel eyes. He was known to use the name "Steven" or the nickname "Steve." His case has remained unsolved for decades, with few details emerging about what might have happened to him after his disappearance. Authorities, including the Santa Cruz County Sheriff's Department, continue to treat his case as missing, hoping for new information to surface.
