The Circleville Letters: A Small Town Stalked by an Anonymous Killer

You walk to your mailbox in a small Ohio town where everyone knows your name. Inside is an envelope with no return address, postmarked Columbus, written in aggressive block letters. It says they know what you did. It says they have been watching your house. It says they know about your children. For nearly two decades, the people of Circleville lived under a writer who seemed to know everyone's secrets, sent more than a thousand of these letters, and was eventually tied to a death and a booby trap. A man went to prison for it. The letters kept coming while he sat in solitary confinement.

This week on Mugshot Mysteries, Kathryn and Gabriel cover the Circleville Letters: anonymous terror, small-town secrets, and a case that is still officially unsolved.

We start with Circleville itself, a town of about fourteen thousand where intimacy cuts both ways, and the cultural moment the letters emerged from, post-Watergate America, when exposing hidden truths felt almost righteous. The first letters in the late 1970s accused bus driver Mary Gillispie of an affair with the school superintendent. Then her husband Ron began receiving nastier ones, urging him to stop her or face danger. We trace how the campaign spread until much of the town was finding accusations in the mail, including vile signs targeting Mary's young daughter that Ron tore down each morning before she could see them.

Then it turns deadly. In 1977 Ron got a phone call, said he finally knew who the writer was, grabbed his gun, and never came home. His truck was found wrapped around a tree, his gun fired once, his blood alcohol high, in a death his family never accepted as the accident it was ruled. We dig into the psychology the case keeps surfacing: deindividuation and the disinhibition of anonymity, narcissistic supply, moral licensing, and the terrible power that comes simply from knowing things about people.

We cover the 1983 booby trap, a loaded pistol rigged to a roadside sign meant to kill Mary, the gun traced to her brother-in-law Paul Freshour, his estranged wife's accusation in the middle of their divorce, his failed polygraph, and his conviction. And then the part that breaks the tidy story wide open: the letters did not stop. They kept arriving while Freshour was in solitary with no access to writing materials, leading to the theory that the wrong man was convicted, or that the Circleville writer was never just one person. We run the full suspect list and the unsettling fact that some of the writer's most vicious accusations, against a prosecutor and a coroner, turned out to be true.

And we close on the thread running underneath the whole episode: the writer had power because the town read the letters, and we are doing a version of the same thing right now.

This is the Circleville Letters.

The Circleville Letters case is officially unsolved, and the identity of the writer or writers has never been definitively established. Paul Freshour was convicted of attempted murder in 1983 and is identified here in that context; he maintained his innocence until his death, the anonymous letters reportedly continued while he was incarcerated, and serious questions remain about whether he was responsible for the letters at all. Nothing in this episode should be read as a statement that he, or any other named individual, wrote the letters or caused Ron Gillispie's death. The alternative theories discussed, including the possibility of multiple writers, are unproven interpretations offered so listeners can weigh them, not established fact.

Several people connected to this case are or may be living, including Mary Gillispie and her family. Their private lives are discussed only as they appear in the public record of a widely reported case, and references to them, and to any person living or deceased, are made in the context of documented reporting and are not intended to defame, harass, or cause harm. The separate criminal charges against individuals named in the episode are matters of public record and are distinct from the letter-writing case.
