Paranormal investigator Dan Rivera died suddenly on the ‘Annabelle’ haunted doll tour over the weekend.

US Army veteran Dan Rivera attended the “Devils on the Run Tour” in Gettysburg, Pennsylvania when things took a turn for the worse and paramedics were called in.

He received CPR but sadly, the 54-year-old died on site.

His cause of death has yet to be released.

He worked as a paranormal investigator on the “Most Haunted Places” tour and also worked as a producer on multiple other shows, such as “28 Days Haunted” on Netflix.

The company had been touring the US with the scary Annabelle doll.

Tragedy struck after he finished his three-day sellout tour at the Soldiers National Orphanage on Monday.

Paranormal Investigator Ryan Buell paid tribute to the legend on TikTok: “I have so many amazing memories with this guy. Just as recently as two months ago, we traveled around the country and introduced a whole new generation to Ed and Lorraine Warren’s legacy,”.

The doll has been linked with conspiracy theories since the 1970s, including a series of hauntings and even one where people are convinced the doll stabbed a police officer and caused a motor accident.

RIP.
