Case Details:Joseph Thomas, also identified in records as Joseph Edwin Thomas, was 57 years old when he was last seen in Oacoma, South Dakota, on November 1, 2018. He has not been located since. Reporting sources differ on Thomas's physical description: he has been described both as White/Caucasian with brown hair and brown eyes, and separately as American Indian/Alaska Native with black hair and brown eyes, standing approximately 5'9" and weighing between 130 and 150 pounds depending on the source. No independently verified record of Thomas's exact height, weight, race, or clothing at the time of disappearance was located; these details should be confirmed against the primary agency file before publication.

Thomas's case is catalogued with the National Missing and Unidentified Persons System as NamUs #MP131157, and is also tracked by the South Dakota Missing Persons Clearinghouse under case number 24-982. One open-source aggregator lists a "Gilroy Police Department" (Gilroy, California) contact for the case, but this could not be corroborated and appears inconsistent with a South Dakota case; the investigating agency should be confirmed directly rather than relied upon from that source. Thomas's case remains open. Anyone with information is asked to contact the investigating agency of record or submit a tip through NamUs.
