The Circleville Letters

Beginning in 1976, residents of Circleville, Ohio began receiving anonymous letters containing detailed personal secrets, sexual accusations, and threatening demands. The primary target was Mary Gillispie, who the letters accused of having an affair with the local school superintendent. The letters were visceral and specific in a way that suggested the author had intimate knowledge of local lives and relationships. Over the following years, the letter-writing campaign escalated, eventually reaching other residents and becoming increasingly menacing. In 1977, Mary Gillispie's husband Ron died when his truck ran off the road and flipped — a death ruled accidental but suspected by some to have been caused by booby-trapping. The mystery deepened when Mary herself received a box that appeared to have been rigged as a trap. Investigators eventually focused on Paul Freshour, Mary's brother-in-law, based on handwriting analysis and circumstantial evidence. He was convicted of attempted murder in connection with the booby-trapped box and was imprisoned in 1994. The case took a bewildering turn when the letters continued to arrive even after Freshour was incarcerated. Prison officials confirmed he had no access to outside mail channels that would have allowed him to send them. The letters mocked investigators for looking in the wrong direction. Freshour consistently denied writing the letters and was never charged with anything related to the correspondence campaign itself. The Circleville letters case remains unsolved in the deepest sense — the author was never conclusively proven to be Freshour or anyone else. The case was featured on Unsolved Mysteries and attracted national attention. It is considered one of the most unnerving anonymous harassment campaigns in American true crime, raising enduring questions about what really drove the letter-writer and what they truly knew.
