7 Mysteries That Are Still Unexplained

1) Circleville Letters

Despite this story gaining national attention at the time, the Circleville letter writer was never caught. In 1976 residents of Circleville, Ohio, so named for the town’s original circular shape which was built on Native American mounds, began receiving threatening letters. The most famous case was Mary Gillespie, who was theatened to confess her alleged affair or else be exposed. One year later her husband was found dead in apparent car accident, with high blood alcohol levels, after receiving a mysterious phone call.

The letters continued after the car accident, and eventually escalated in Mary’s case to signs placed along her morning route. When she attempted to remove one, she found a loaded gun pointed at her- a string around the trigger. Her former brother-in-law, Paul Freshour, owned the gun and he was convicted of attempted murder. But, the letters didn’t stop while he was in prison and in fact he got a letter himself while incarcerated! Freshour maintained his innocence until his death in 2012 and the letter writer was never caught.

Gillespie did, however, admit to the affair, though she claimed it only started once the letters began. We’ll never know if there were 2 letter writers or if perhaps there were 2 different crimes committed (framing the car accident as a fluke? framing Freshour using his gun?). Despitebeing covered by Unsolved Mysteries in 1993 the details of the case have never really lined up.
