Summary based on the NamUs case record (MP9062) and 6 other sources
Windsor Dennan Thomason, a 64-year-old man, was last seen on December 27, 1991, in Rendon, Texas. He had spent the day with his daughter and grandchildren, giving them Christmas presents, but was not heard from again after that visit. His disappearance has raised suspicions of foul play, particularly because of inconsistencies in the statements given by his wife, Amanda Gladys Crawford. Despite her various explanations about his whereabouts, such as claims that he had gone to Mexico or was suffering from illness, no solid evidence has emerged to confirm these stories.

Thomason led a tumultuous life before his disappearance, having served in both World War II and the Korean War after enlisting in the Marines. His personal life was equally troubled, involving multiple marriages and a violent past, including the shooting of his first wife’s lover in 1966. Though he was not indicted for that act, his relationships remained complicated, with many divorces and reconciliations.

Thomason's case was officially reported to the authorities in June 1992 by one of his daughters, who had grown suspicious of the situation. Subsequent investigations found that Crawford had been using Thomason’s pension and Social Security payments, further deepening concerns of foul play. Despite extensive investigations, including handwriting analysis and interviews with key individuals, there has been insufficient evidence to charge anyone with a crime, and Thomason’s body has never been found. Authorities and his family believe he may have been murdered, and he has since been declared legally dead. His case remains unsolved, and foul play is strongly suspected.
