Summary based on the NamUs case record (MP56077) and 4 other sources
Robert John Yandell, a 25-year-old man, went missing from Alameda, California, on January 14, 1983. He was last seen in the area and has not been heard from since that day. Yandell is described as a Caucasian male, 5'10" in height and weighing approximately 180 pounds, with black hair and brown eyes. Notably, he has a tattoo on his left forearm. Despite efforts from the authorities, including the Alameda Police Department, few details surrounding his disappearance have surfaced, and his case remains unsolved.

Yandell's family reported him missing after he failed to return home, and his whereabouts have remained a mystery for over four decades. Law enforcement continues to investigate, and his case is listed in multiple missing persons databases. However, no significant leads or evidence have been reported in the years following his disappearance, making his case another cold missing person file that continues to require public assistance and new information to advance the investigation.
