Who Wrote the Circleville Letters?

Background

Beginning in 1976, residents of Circleville, a small town in Pickaway County, Ohio, started receiving anonymous letters accusing them of affairs, embezzlement, and other private wrongdoing, often citing personal details that suggested the writer was watching their homes and daily movements. The letters settled quickly on a central target: Mary Gillispie, a local school-bus driver, whom they accused of having an affair with Gordon Massie, the married superintendent of her school district. Both denied the accusation at the time. Mary and her husband, Ron, told almost no one about the letters outside their immediate family, but the writer's knowledge of private details, and a growing habit of posting signs along Mary's own bus route, made the campaign impossible to keep quiet for long.

The letters took a darker turn on 19 August 1977, when Ron Gillispie died after his car left the road and struck a tree. According to the couple's children, Ron had received a phone call shortly beforehand that visibly angered him; he took his handgun, told them he intended to confront the letter writer, and drove off alone. The county coroner ruled the crash an accident, but Ron's family has long argued the ruling did not account for everything investigators found, including a blood-alcohol reading the family says was inconsistent with his known habits and the discovery that his own gun had been fired once before the crash. No inquest has ever reopened the death as a homicide, and no evidence has ever formally tied it to the letter-writing campaign, but the timing has made it a permanent, unresolved part of how the case is understood.

The 1983 Booby Trap and Paul Freshour's Conviction

The letters and signs continued through the early 1980s, still centred on Mary Gillispie and her family. On 7 February 1983, while driving her bus route, Mary spotted a new sign accusing her daughter of scandal. When she stopped to pull it down, she found it wired to a box containing a loaded handgun, rigged so that disturbing the sign would fire the weapon at whoever removed it. The gun failed to discharge, and Mary was unhurt. Investigators at Ohio's Bureau of Criminal Investigation traced the weapon to Paul Freshour, who was married to Ron Gillispie's sister, Karen, making him brother-in-law to both Ron and Mary and a member of the wider Gillispie family circle who had known about the letters from early on.

Freshour went on trial in October 1983, charged not with writing the letters but with the attempted murder of Mary Gillispie over the booby-trapped gun. Prosecutors could not directly place him at the scene, and no fingerprints were recovered from either the gun or the box housing it. The case against him rested substantially on two document examiners' testimony that his handwriting matched thirty-nine of the anonymous letters admitted at trial, evidence the prosecution used to establish motive and character even though authorship of the letters was never itself a charge. Freshour denied any involvement in either the booby trap or the letters. He was convicted and sentenced to seven to twenty-five years in prison. That conviction for attempted murder stands as a documented legal fact, distinct from the separate, and never legally resolved, question of who wrote the letters.

Letters During and After Freshour's Imprisonment

The letters did not stop when Freshour went to prison. Circleville residents, including Freshour himself, kept receiving them throughout his incarceration, in a style and content consistent with the earlier campaign. Prison officials stated that for at least part of his sentence Freshour was held in solitary confinement, without access to pen, paper, or unmonitored outgoing mail. Defenders of Freshour have treated this as close to conclusive evidence that he could not have written the letters sent during that period, a detail prosecutors and later re-examiners have had to explain rather than dismiss.

The case drew national attention in the early 1990s when the television series Unsolved Mysteries began investigating it. In December 1993, before filming had even begun, the production received an anonymous, threatening postcard warning the show not to pursue the story and not to endanger the sheriff investigating the case, signed "the Circleville Writer." The resulting episode aired on 11 November 1994. Freshour was paroled that same year after serving roughly a decade of his sentence. The last letter documented in the case was postmarked 21 November 1994, shortly after his release, and was sent to Martha (Marie) Mayhew, a local journalist who had been covering the story; it warned her to stop writing about it. No letter matching the campaign's style has been publicly reported since.

Main Theories

The case that Freshour was the writer

The theory that Freshour wrote some or all of the letters rests on the handwriting evidence used at his 1983 trial, on his ex-wife's statements to investigators that she had found similar letters in their shared home, and on his direct, documented connection to the gun used in the booby trap. In 2021, and again in a CBS 48 Hours episode broadcast on 25 May 2024, forensic document examiner Beverley East said that after comparing a sample of forty-nine of the anonymous letters against Freshour's known handwriting, she was confident the same person had written both, pointing to a distinctive formation of the letter "G" and certain numerals that recurred across the set, including, in her assessment, some letters sent while Freshour was already incarcerated. The same 48 Hours investigation also reported finding Freshour's fingerprints on roughly a dozen letters postmarked during his imprisonment, a finding it and other outlets describe as an unexplained contradiction rather than a solved one. Under this theory, the letters that continued to arrive after his 1983 arrest would have to be explained by means investigators have never fully established: correspondence smuggled out around the restrictions, a period of prison access looser than officials later described, or help from someone else acting on his account.

The case for his innocence

Freshour maintained he had never written a single letter and had no part in the booby trap, and several documented facts complicate the case against him. No fingerprints tied him to the gun or the box. Investigators at the time noted a witness description of a large, sandy-haired man driving a Chevrolet El Camino near the booby-trap site shortly before its discovery, a description that did not match Freshour and was never conclusively linked to anyone else. Prison records confirming his solitary confinement without writing materials remain the strongest single piece of evidence in his favour, since letters plainly continued reaching Circleville on his watch regardless of what caused them. Retired FBI profiler Mary Ellen O'Toole, reviewing the case decades later, expressed doubt that Freshour's background as a machinist with a stable professional life fit the profile more typically associated with sustained anonymous harassment campaigns of this kind. None of this amounts to a rival suspect ever being named, charged, or convicted; it amounts to an unresolved gap in the case against the one person who was.

Common Misconceptions

A common misunderstanding holds that Paul Freshour was convicted of writing the Circleville letters. He was not: his 1983 conviction was for the attempted murder of Mary Gillispie over the booby-trapped gun, a charge on which handwriting evidence was introduced as supporting testimony rather than the basis of a separate authorship charge, because he was never indicted for writing anything.

A second misconception treats the case as effectively solved by the 2024 48 Hours investigation. Beverley East's handwriting analysis is a serious, named forensic opinion, but it has not been adopted as an official finding by Ohio law enforcement, has not reopened the case, and has been publicly disputed by other researchers on the strength of the same solitary-confinement records that have divided opinion on Freshour's guilt for four decades. The Pickaway County Sheriff's Office treats its own investigation as closed without naming a confirmed author.

A third misconception assumes Mary Gillispie's relationship with Gordon Massie, which the two say began only after Ron's 1977 death, proves the original letters were baseless gossip. Gillispie and Massie have always denied that any affair predated the letters, while Freshour and some other researchers who have examined the case have argued a relationship existed earlier. Neither account has ever been independently confirmed, and the dispute concerns a private relationship between people who were, at the time, both accused rather than convicted of anything, a distinction this page maintains throughout.

Current Consensus

Investigators and researchers agree on the documented sequence of events: an anonymous letter and sign campaign that began in 1976 and continued for roughly eighteen years, a booby-trapped gun traced to Paul Freshour in 1983, and Freshour's conviction that same year for the attempted murder of Mary Gillispie. What remains genuinely unresolved is who wrote the letters. Freshour's conviction for attempted murder is settled law; the authorship of the letters, including those that continued to arrive during his confirmed solitary confinement, has never been legally established either for or against him. The 2024 forensic re-examination for 48 Hours represents the most recent serious attempt to close that gap, and it has not achieved consensus acceptance among researchers who have studied the case. The Circleville letters remain, in the strict sense, an unsolved case: no one has ever been charged with writing them, and Ron Gillispie's death has never been formally connected to the campaign at all.

Why This Mystery Endures

The Circleville letters case endures because it offers two separate, incompletely resolved questions layered on top of each other: whether the man convicted of the attack was also the writer, and whether the letters that kept arriving after his imprisonment prove he was not, or simply prove someone else's involvement went undetected. Few American cold cases combine a documented criminal conviction with such a well-attested, unresolved gap in the very evidence used to secure it, which is what keeps true-crime writers, podcasters, and forensic examiners returning to the same forty-nine letters four decades later.

The case is frequently paired with the Zodiac Killer for a specific reason: both are built around an anonymous figure who chose to communicate directly and repeatedly with victims, police, or the press, and whose identity has been pursued mainly through analysing the writing itself rather than through physical evidence, DNA, or a confession. The comparison also sharpens the difference between them: the Zodiac Killer was never identified at all, while Circleville has a convicted defendant whose connection to the letters, unlike his conviction for the attack, was never legally tested. The Somerton Man case offers a different kind of parallel, one of contested identification rather than shared method: for over seventy years, competing theories about the Somerton Man's identity divided investigators and amateur researchers in much the way Freshour's guilt still divides Circleville, until forensic genetic genealogy finally confirmed his identity as Carl Webb in 2022. It is a clean resolution the Circleville case has never had and may never get, given how much of its physical evidence and testimony is now decades old.

Within this site's broader unsolved crimes coverage, Circleville sits closest to the Hinterkaifeck murders and the Villisca axe murders: all three involve a strong, publicly named suspect whose link to the crime's central mystery, the killer's identity at Hinterkaifeck and Villisca, the letters' authorship at Circleville, never crossed the threshold of a formal charge, trial, or confession, even where, as with Freshour, the same person was separately convicted of a related act. The Black Dahlia case and the Setagaya family murder show the harder version of the same pattern, an unidentified killer rather than a disputed convicted one, while the Gardner Museum heist shows the mirror image: culprits investigators say they have identified, with no prosecution ever possible. Circleville's distinguishing feature among all of them is that its central legal question, whether Paul Freshour wrote the letters, was never actually put to a court at all. A documented conviction sits permanently beside an authorship case that was argued everywhere except where it could have been settled.
