HBO’s ‘Pet Cemetery Murders’ and the ghost said to reopen a case

Ghost stories usually follow a crime. In St. Bernard Parish, just downriver from New Orleans, people say one helped bring a crime back into court. That claim is the hook of The Pet Cemetery Murders: A Ghost Story, a three-part HBO documentary series that premiered on Sunday, October 11, 2026. The second episode airs on October 18 and the last on October 25, and all three stream on HBO Max, according to Biography.com’s guide to the series.

Philip Cairney wrote and directed the series for HBO Documentary Films and the production company Lightbox. Early reviews are interested in the case more than the ghost. Noel Murray, reviewing it for The A.V. Club, found it tightly focused but conventional, and wrote that there are “(probably) no literal ghosts in St. Bernard.”

A woman, a pet cemetery and a land dispute

The real story starts with Dorothy Lou Thompson, who ran the Azalea Original Pet Cemetery in Toca, a small community in eastern St. Bernard Parish, with her mother. According to 2014 reporting in The Advocate and on FOX 8 in New Orleans, the case grew out of a fight over the cemetery’s 14 acres. Investigators said a former handyman on the property and his wife had tricked Thompson into signing the land over to them. Biography.com, drawing on news coverage of the time, says the title changed hands in 1984 while she was heavily medicated, and that she sued that November to get it back.

Thompson, 61, disappeared from her home on April 13, 1985, about ten days before the case was due in court. Fishermen found her body in the Mississippi River in neighboring Plaquemines Parish on May 2, 1985, and the coroner found that she had been suffocated. The handyman, Brandon Nodier, was the obvious suspect, but there was no physical evidence to charge him, and the case went cold for more than two decades.

Where the ghost comes in

Biography.com reports that a St. Bernard detective, John Doran, reopened the file in 2009, the same year an anonymous caller told police that Thompson’s ghost was haunting them and that Nodier had confessed. The breakthrough came in 2012. The Advocate reported that on March 15, 2012, a jailed man named James J. Tregler, a former assistant groundskeeper, contacted the authorities after Nodier visited him in the St. Tammany Parish jail and threatened him and his wife. Tregler, who was given immunity, told a grand jury he had been with Nodier the night of the killing. Biography.com says he also told investigators that Thompson’s ghost had haunted him.

New Orleans public radio station WWNO, introducing an interview with Cairney on October 7, summed up the series’ premise the same way: decades later, a witness came forward saying Dorothy’s ghost had pushed him to talk.

The legal outcome is a matter of public record. Nodier was indicted for second-degree murder in 2012. In July 2014, at the age of 60, he pleaded guilty to manslaughter in a deal with prosecutors and was sentenced to ten years by Judge Perry Nicosia in Chalmette. His lawyer conceded to The Advocate that the prosecution’s case was thin, and Sheriff James Pohlmann, who said he would have liked a life sentence, called the outcome “some form of justice.”

They didn’t have a great case.

Reading a ghost story in a murder file

Nothing in the court record treats a ghost as evidence. The case that put Nodier in prison rested on a living witness, and The Advocate noted that this witness came with credibility problems: he had pleaded guilty to bomb-related charges in 1990 and 2011. His stated reason for coming forward, as reported in 2014, was very earthly: he had been threatened. The same report adds another strange detail: early in the investigation, State Police had brought in a psychic from Slidell, who visited the cemetery and offered an account of what had happened. Investigators were open to unusual leads, but in the end they built the case from people’s testimony.

None of that makes the ghost stories dishonest. The sheriff’s office itself told The Advocate in 2014 that several people connected to the case had told stories about Thompson’s alleged ghost, and that “lore has grown up” around it. Guilt, fear and grief are powerful feelings, and people have long described them in the language of hauntings. A witness who had kept a secret for nearly three decades might well feel that the dead woman would not let him rest. A ghost is also a useful way to tell such a story: it explains why someone has finally come forward, and it turns a grim land fraud into a legend.

The case has a famous ancestor. In 1897, in Greenbrier County, West Virginia, Mary Jane Heaster said her dead daughter Zona’s spirit had told her she was murdered. An autopsy found a broken neck, and Zona’s husband was convicted. But the prosecution never mentioned the ghost at trial; it was the defense that raised it. The Greenbrier Ghost is still often called the only case in which a ghost helped convict a killer. St. Bernard’s version follows the same pattern: the ghost gets the credit, and the paperwork shows ordinary detective work.

Watching it

Murray’s review notes that the series also looks at the parish’s older history of violence, and that Hurricane Katrina destroyed much of the evidence investigators had hoped to test again with new DNA methods. For viewers interested in hauntings, the series is a good look at how ghost lore grows around a real crime. The woman at its center was real, and so was her fight to keep her land, and that is worth keeping in mind while watching.
