Stephen King’s son, author Joe Hill, has revealed a theory he believes could identify an unnamed woman in an unsolved 1974 murder case.

Hill, 46 (real name Joe Hillstrom King), previously wrote about the whole thing in a 2015 Tumblr post; he’s now spoken further about it to The Washington Post.

The writer thinks he’s spotted a link between Steven Spielberg’s classic “Jaws” and the murdered woman known only as the “Lady of the Dunes”. She was found dead on July 26, 1974, with a severed head and her hands cut off.

No one has come forward to give the woman’s identity. However, Hill insists she bears a striking resemblance to one of the extras in the hit horror movie.

The “Lady of the Dunes” was found just outside Provincetown, Massachusetts, around 100 miles from Martha’s Vineyard, which was the location used in the movie.

Hill says he is often told that “everyone who was out on Cape Cod in the summer of 1974 appears in the movie ‘Jaws’… I’m sure that’s an exaggeration, but there’s a nugget of truth.”

According to the author, one of the tell-tale signs was that both women were wearing blue bandanas, and according to a recently released facial reconstruction pic, they both had similar hairstyles.

The woman in “Jaws” also appeared to be between 20 and 40 years old — the age at which the woman in question is thought to have died, and weighed around 145 lbs. Read more about her here.

Hill wrote a few years ago, “My thing is writing ghost stories. I can’t tell if this is my imagination just doing the thing that it always does or if there’s actually something there.”
