Summary based on the NamUs case record (MP21937) and 2 other sources
Robert Allen McDowell, aged 33, was last seen on July 15, 1993, in Brownsville, California. On the day of his disappearance, McDowell left his mother's home after borrowing some money, stating that he planned to visit his wife and child in Antioch, California. However, he never arrived at his destination and has not been heard from since. At the time of his disappearance, he was wearing a black Harley Davidson t-shirt and black pants. McDowell had several distinctive tattoos, including a lightning bolt and a peacock on his arms, a wizard on his left arm, and an eagle with the name "Nadine" on his chest.

Despite the efforts of the Antioch Police Department, who continue to investigate the case, little information has surfaced regarding McDowell's whereabouts. His case remains unsolved, and authorities urge anyone with information to come forward.
