According to PEOPLE, the Adams County coroner said in a statement Thursday that Rivera’s cause of death was cardiac related. His death was ruled as natural. The coroner also said that Rivera had a known history of heart issues and that the Annabelle doll was not in the room with him when he died. Officials said Rivera, 54, was found dead in July in his hotel room the day after an event in Gettysburg, Pennsylvania, that featured the iconic doll.

The coroner noted that there was nothing unusual or suspicious about the death. Paranormal Investigator Dies During Tour with “Anabelle” Doll, Built Crate to Contain Its “Demonic” Powers pic.twitter.com/iVPKvVXXBc — TaraBull (@TaraBull808) July 16, 2025 People provided some history behind the Annabelle doll: Annabelle the doll is a real antique Raggedy Ann doll, and it is believed to be haunted or “possessed.” According to the NESPR case file on Annabelle, the demonic toy was bought by a mother in 1970, who gave it to her daughter, Donna, as a birthday present. Fast forward, Donna was about to graduate from nursing school and lived with her roommate, Angie. Shortly after the doll entered their apartment, strange and unexplained occurrences started happening, like the doll seemingly moving and changing positions by itself. Donna and Angie began to find parchment paper around the house with messages written on it, like “Help us” and “Help Lou,” who was their friend. The messages were even more bizarre because they didn’t keep parchment paper in their apartment. The 2014 horror film, Annabelle, is an origin story of the allegedly haunted doll, but the plot is fiction. While Annabelle the doll is real, the movie is not a true story. In Annabelle, a female cult member named Annabelle Higgins kills herself while holding the doll, and the demon she helped summon possesses it afterward. In real life, Donna and Angie contacted a medium in an attempt to speak with whoever was inhabiting the doll. During a seance, it was revealed that the spirit of a 7-year-old girl named Annabelle Higgins, who had died on the property before the apartments were built, was controlling the doll. Donna and Angie thought Annabelle was just an innocent spirit, but their friend Lou was not convinced. Per NESPR, Lou was attacked by Annabelle and bled, which led Donna to contact an Episcopal priest, Father Hegan, who spoke to Ed and Lorraine about the supernatural event. After connecting with Donna, Angie and Lou, the Warrens “came to the immediate conclusion that the doll itself was not in fact possessed but manipulated by an inhuman presence,” according to the NESPR case file. The paranormal investigator couple explained that spirits do not inhabit inanimate objects; only inhuman spirits do. According to the New Haven Register, she and Ed took the doll and brought it back to their house. They almost crashed their car along the way, and experienced a series of supernatural events in their home after Annabelle arrived, per NESPR.
