The paranormal expert thinks "Satan's minions" are haunting the real home that inspired The Exorcist

Exorcism: Live! Medium Chip Coffey: 'There's Something Dark at This House'

What’s haunting the house that inspired The Exorcist? Psychic medium Chip Coffey has an idea.

“They’re demons,” he says in an exclusive preview for the upcoming Exorcism: Live!, a special that will broadcast Coffee, Bishop James Long and the Tennessee Wraith Chasers trying to cleanse the home outside of St. Louis. “They’re Satan’s minions. They’re his worker bees, his drones.”

The night before Halloween, Coffey is tasked with conducting a séance with whatever is possessing the house – and he says the worst-case scenario is that “all hell will break loose” during the first-ever live exorcism on TV.

“There’s something dark in this house,” he says. “That’s not a question mark.”
