Almost everyone in the western world takes notice, at least in passing, when the thirteenth of a month falls on a Friday. Many people are blatantly superstitious about such a day- some considering it lucky, some unlucky- but widely associated with luck in some fashion. In fact, considering that the belief in the significance of the day is only about a century old, it is maybe even a little surprising how nearly universal it is in the English-speaking world, and beyond.
Individually, though, superstitions about the number thirteen (the most popular superstition in the world, according to author Nathaniel Lachenmeyer) and Fridays in general have existed for a great deal longer. Both have roots in the Christian gospels- the old “thirteen at a table” rule (which appears to be the oldest superstition about the number), after that fiasco at the Last Supper, and the universal agreement in scripture that Christ’s execution took place on a Friday. Until recent decades, executions in general were typically carried out on Friday, contributing to its somewhat grim reputation.
Since the 1980 debut of Shaun Cunningham’s film of that title and its subsequent franchise, Friday the 13th has taken on a somewhat ‘spookier’ connotation in, and when it takes place in October some even take it as cue to start getting in Halloween mode early. For some though, it can be a cause of serious anxiety. There is even a name for this: triskaidekaphobia, an overwhelming and irrational fear of Friday the 13th (as opposed to jasospacephobia, which is merely an extreme repulsion to Friday the 13th Part X).
Some people have even more convoluted ways of relating to the pop culture of the day. This is the story of how Friday the 13th came to life and terrorized the town of Greenfield Massachusetts through Halloween, 1988. That is, at least as much of it as ever leaked out to the press.
Mark Branch was an 18 year old grocery store clerk with an avid interest in slasher films. As the clerk at Video Expo 1 in Greenfield put it later: “He rented strictly gore, period. The gorier, the better.” He was particularly entranced with the Friday the 13th series, and its machete-wielding protagonist, Jason Vorhees. Some might have called it an obsession.
Perhaps that’s the way it might have been described by Sharon Gregory, a freshman psychology major at Greenfield Community College. Sharon was apparently intrigued enough by Branch to do some sort of psychological profile on him. Curiously, police were later unable to confirm that this was done as part of her course work. Just how well acquainted the two were is opaque, but what is known is that Mark knew that Sharon had written up a psychological profile of him, and that he wanted it.
On the night of October 24, Mark donned Jason’s trademark hockey mask and big black boots, and headed for Sharon’s apartment. What exactly transpired will never be known. Her twin sister found her mutilated body in the bathroom, having been stabbed repeatedly in the head, chest, and abdomen.
Police honed in on Branch as a suspect immediately, and suspicion of his guilt became a growing certainty when they found his bloodstained car abandoned near the woods in nearby Buckland. A massive manhunt ensued, but the Jason copycat remained undiscovered. As Halloween approached and more and more sensational media coverage came out about Branch’s obsession with Friday the 13th, area residents became increasingly frightened. Greenfield cancelled its Halloween parade and downtown activities, and confined trick-or-treat to afternoon hours. The local movie theater even agreed to postpone the release of Halloween IV- though how exactly that helped is somewhat unclear. Perhaps they feared that Branch would show up to attend the film- after all, Jason is, to a large extent, just a rip-off of Michael Myers.
Everyone seemed convinced that Branch would show up around Halloween for some kind of climactic slaughter, demonstrating that perhaps he was not the only one who’d seen one too many slasher movies. In fact, Halloween passed without incident, and also without new breaks in the search for Branch, despite the involvement of reputed psychic John Monti. There were no new developments in the case until late November, when a hunter discovered Branch’s body hanging from a tree in the woods of Buckland. The coroner determined that Branch’s suicide took place shortly after the slaying of Sharon Gregory.
Attempts to draw out more sensational details of the case, particularly those surrounding Branch’s obsession with Friday the 13th, were made by local newspapers, who petitioned the courts to release documents pertaining to the murder and to evidence confiscated from Mark’s home. The motions were successfully blocked by an attorney for his family, and the story essentially ground to a close, wrapping up with a quote from Greenfield police chief David McCarthy:
“He was so entrenched with Jason that he had to have the Final Chapter in his own feelings. He wanted to know what it felt like to live out the part of Jason,'' McCarthy said.
