The owner of an extreme and controversial Halloween attraction was arrested Friday on suspicion of the rape and attempted murder of his girlfriend.

Russ Alan McKamey is the owner of McKamey Manor in Lawrence County, Tennessee, a terrifying haunted house at the center of a state investigation and Hulu documentary for its practices.

McKamey has been charged with repeatedly assaulting, raping and attempting to murder his girlfriend over a three-day period, according to court records reviewed by HuffPost.

Police described multiple instances where McKamey was violent with his girlfriend, including one domestic altercation in which he strangled her until she was unconscious, according to an arrest affidavit cited by local Nexstar affiliate WKRN. McKamey was reportedly arrested following another alleged rape and strangulation, during which the woman lost consciousness again.
