Summary based on the NamUs case record (MP11647) and 5 other sources
Usbaldo Arvizu Hernandez, a 44-year-old Hispanic male, was last seen on July 1, 1969, in Los Angeles, California. At the time of his disappearance, Hernandez was approximately 5'9" tall and weighed about 150 pounds, with black hair and brown eyes. He had a distinctive black ink tattoo of an eagle with its wings spread on his upper right arm. He also went by the nicknames "Waldo" or "Oswaldo" and was known for frequently riding trains between California and Arizona, as he did not own a vehicle.

Hernandez had served in the military and later worked as a migrant farmhand. His tendency to travel across state lines by hopping trains made it difficult to trace his movements after he went missing. He had been living a somewhat transient lifestyle, traveling between states regularly. Since the day of his disappearance, no further information or sightings have emerged, leaving his case unsolved for over five decades. Despite multiple investigations, including involvement from the El Dorado County Sheriff's Office, his whereabouts remain unknown.
Last Seen: Jul 1, 1969
