Circleville Letter Writer. Circleville, Ohio. Letters were first mailed out in 1976 accusing a bus driver of having an affair with the superintendent of schools. At first she simply ignored them. Then letters were mailed to her husband. The threats from the anonymous writer prompted the woman and her husband, as well as a few other people, to mail letters to the person they suspected of being responsible, but the letters and threats only stopped for a few weeks. In 1976, Ron Gillespie, gun in hand, rushed out of his house after receiving a phone call. His truck would be found just down the road crashed into a tree and he was dead behind the wheel. His gun had been fired once, but it could not be determined why. In 1983, his wife Mary, the bus driver, removed a sign that had a box with string attached on her route that seemed to be from the mysterious letter writer. Once home, she took it apart and discovered that it was a booby trap. A gun was set to go off if tampered with. An arrest was made soon after. Was it the letter writer?
