In 1976, people in Circleville, Ohio, began receiving anonymous letters written in block capitals. Many went to Mary Gillispie, a school bus driver, and accused her of an affair with a school official. The writer claimed to be watching her house. In August 1977, her husband Ron Gillispie left home after a phone call, apparently to confront the letter writer. His truck ran off the road and hit a tree. His gun had been fired once. His death was ruled an accident. The letters continued and spread to hundreds of residents, officials and businesses across the county. In 1983, Mary stopped at a roadside sign that insulted her daughter. Behind it was a pistol rigged to fire at anyone who pulled the sign down. The gun was traced to Paul Freshour, her former brother-in-law. Freshour was convicted of attempted murder and sentenced to seven to twenty-five years. A handwriting expert testified that he had written the letters. The letters did not stop. They kept arriving while he was locked up, including one sent to Freshour himself in prison. He was paroled in 1994, and the letters tapered off around the same time. He denied any involvement until his death in 2012. The writer has never been identified. The creepiest photos ever taken:
