Summary based on the NamUs case record (MP22913) and 2 other sources
Donald Robert Dumas, aged 27, was last seen on July 14, 1971, in Rosemead, California. He left his residence around 6:00 PM that evening but never returned home. At the time of his disappearance, Dumas was described as standing 5'10" tall, weighing about 170 pounds, with brown hair and brown eyes. He was last seen wearing a short blue shirt, blue pants, and brown boots.

Despite initial efforts, very few details surrounding his disappearance have surfaced. There is no indication of where he might have been heading that evening, and investigators have found no clear leads over the decades. Dumas's case remains open, and authorities are still seeking information that could provide closure for his family and friends.

Efforts to locate Dumas or uncover new leads in his case have included involvement from national missing person databases such as NamUs. His disappearance remains unsolved, and anyone with information is encouraged to contact the appropriate authorities.
