As investigators tried to figure out who would have killed the bubbly mother of two children who seemingly had no enemies, they began to wonder if a popular movie had inspired the killings.

“It looked like a scene from a horror film,” former Collin County sheriff’s deputy Steve Deffibaugh tells PEOPLE in its latest issue. “It was a Friday the 13th. Our thought was that we had a copycat of the movie ‘The Shining.’

The iconicJack Nicholsonmovie had been released on May 23 of that year — just 3 weeks before Gore was killed. Press materials at the time showed Nicholson carrying an axe during his rampage in the now-classic horror film.

In a high-profile trial, Candy Mongomery testified that Betty had swung at her with an axe, and she had wrestled the weapon from her friend’s hands and killed her.

Still, there were questions: if Candy Montgomery had acted in self defense, why did she strike her friend 41 times, only stopping because she was exhausted? In her trial, Montgomery testified that Gore had “shushed” her, which triggered memories of her abusive mother.

The defense worked, and Montgomery was acquitted of the murder. She is now living in Georgia, where she works as a mental health counselor.

Now, more than four decades later, the case still has the power to shock, even as it garners fresh attention with two new productions:Candy, starring Jessica Biel, andLove & Death, starring Elizabeth Olsen. The case will also be the subject of an upcoming episode ofPeople Magazine Investigates.
