Yes. HBO’s published announcement says the series debuts on the HBO channel as well as HBO Max, at 9 p.m. ET/PT on October 11. Cable and live-TV viewers should check their local provider’s HBO channel and program guide. Streaming viewers should use the HBO Max listing for the title.
What is the documentary about?
The series follows the disappearance and killing of Dorothy Lou Thompson, who operated the Azalea Original Pet Cemetery in St. Bernard Parish, Louisiana. Her body was found in the Mississippi River in 1985. The case remained unresolved for years before Detective John Doran reopened the investigation in 2009 after new witness information emerged. The documentary also examines the community’s history and witnesses’ claims that supernatural experiences prompted them to speak. Those ghost accounts are claims made by witnesses, not independently verified evidence of paranormal activity.
