Article 5: Is The Pet Cemetery Murders Related to Stephen King’s Pet Sematary? The Truth
The short answer is no. HBO’s The Pet Cemetery Murders: A Ghost Story is a true-crime documentary about the 1985 killing of Louisiana pet cemetery owner Dorothy Lou Thompson. It is not an adaptation of, sequel to, or official tie-in with Stephen King’s horror novel Pet Sematary. The similarity is the pet-cemetery premise and eerie supernatural atmosphere—not a shared story or fictional universe. RogerEbert.com’s review explicitly notes that the HBO documentary is unrelated to King’s novel and the 1989 film.

Why are people comparing the two titles?
Both titles bring a pet cemetery to mind, and both touch on the uneasy boundary between death, memory, and the supernatural. But their formats and foundations are different. The Pet Cemetery Murders: A Ghost Story examines a real homicide investigation and witness accounts. Pet Sematary is a work of horror fiction published in 1983, created by Stephen King.
The documentary’s ghost element comes from witnesses who reportedly said Dorothy’s spirit haunted them or prompted them to talk. Those are witness claims within a real case, not evidence that the HBO series borrows the plot of King’s novel or that supernatural events have been established as fact.

What is Stephen King’s Pet Sematary about?
King’s novel follows Dr. Louis Creed and his family after they move to Ludlow, Maine. Nearby is a makeshift cemetery where local children bury pets killed on a busy road. Beyond it lies a more ominous burial ground with the power to return the dead—but what comes back is not necessarily the same as what was lost.
King’s official website lists the novel’s original release as November 1983 and describes the cemetery and the story’s supernatural premise. The author has also explained that the idea grew from a real-life experience: his family’s cat was killed on a road, and he had to explain the loss to his daughter. That experience inspired a fictional horror story; it is separate from the Louisiana homicide investigated in HBO’s documentary.

What is HBO’s The Pet Cemetery Murders about?
The HBO documentary revisits the disappearance and killing of Dorothy Lou Thompson, who owned the Azalea Original Pet Cemetery in Toca, Louisiana. Her body was found in the Mississippi River in 1985. The investigation remained unresolved for years before witness information helped bring renewed attention to the case. Brandon Nodier eventually pleaded guilty to manslaughter in 2014 and received a 10-year sentence.
The series uses the phrase “A Ghost Story” because witnesses reportedly described paranormal experiences connected to their decision to speak. The careful way to describe that angle is as part of the witnesses’ accounts. It should not be treated as proof that a ghost solved the case, and it does not make the documentary an adaptation of Pet Sematary.

Was the HBO title inspired by Stephen King?
No reliable source reviewed for this article says HBO’s documentary was adapted from or officially inspired by King’s novel. The shared wording is an understandable reason for viewers to ask, but similarity in title or setting is not proof of a creative or legal connection. HBO presents the project as a documentary about Thompson’s murder and the community history surrounding the case.
For reference, the official HBO series page describes the documentary as an investigation into the murder of a pet cemetery owner and the history of violence surrounding the community. Stephen King’s official book page separately describes Pet Sematary as a novel about a fictional family and a burial ground with supernatural properties.
