Marie Beulah Mueller, 43, was last seen March 5, 1972, in Frontenac, Missouri. A mother of two young children, she was in the middle of a contentious divorce from her husband, Dr. Donn Mueller. According to his initial account, he returned from watching planes at the airport to find Marie gone and reported her missing to police five days later; he did not file an official missing persons report until March 30 after consulting an attorney. He told authorities Marie had taken a suitcase, a pistol, jewelry, and a large amount of cash, while her car remained at home, and that she phoned the next day and then hung up.

Friends and her hairdresser told police Marie had been afraid of her husband, and witnesses later reported troubling comments by Donn about fraud and even how one might kill a spouse and dispose of a body. No charges were filed, and Marie was declared legally dead in 1982 or 1983. The file was reopened decades later; searches of the former home, including a dig prompted by a 1972 witness who remembered a freshly planted tree and disturbed soil, produced no new evidence. Foul play is suspected in her disappearance.

Does anyone have memories or information about Marie, the Mueller family, or the Frontenac neighborhood in 1972 that could help this reopened inquiry?
