Summary based on the NamUs case record (MP41476) and 4 other sources
Rudolph David Rangel, aged 27, was last seen in San Francisco, California, on March 13, 1982. At the time of his disappearance, Rangel, who went by the nickname "Rudy," was wearing a black suit. He had several distinguishing characteristics, including an inverted "U"-shaped scar above his left ear, another scar near his sideburn, and a piece of his skull about the size of a quarter missing. Rangel was mentally disabled and suffered from epilepsy, which heightened concerns for his well-being.

Rangel's disappearance has been classified as an endangered missing person case, but few details about the circumstances surrounding the day he went missing have emerged. Despite his vulnerable condition, no significant leads have been found since he vanished. The case remains unsolved, and authorities are still seeking any information that might help resolve it. His case is listed with several missing persons databases, and the San Francisco Police Department continues to investigate.
