Theodore Conrad, one of America's most notorious fugitive bank robbers who infamously stole 215,000 dollars from the Society National Bank in Cleveland, Ohio, in July 1969 before vanishing for over five decades, was officially identified posthumously through extensive genealogical and investigative work conducted by the United States Marshals Service. Investigators discovered that he had lived under the assumed identity of Thomas Thanhardt in Lynnfield, Massachusetts, where he worked a quiet, ordinary life as a golf professional and appliance salesman until passing away from lung cancer in May 2021. Decades of relentless cold-case sleuthing by federal marshals finally matched historical documents, college records, and signature samples, bringing formal closure to one of the longest-running fugitive mysteries in American history.
