Meanwhile, McKinney and a physician, Susan Caitlin Dulany, are investigating the murders and the strange behavior experienced by the comatose Kate. Their investigations lead them to Houngan Julius Harris, who admits that he had brought Cordell back from the dead, and he is interested in Kate who is on the verge of death. At gunpoint, Cordell forces Houngan to attempt the resurrection on her, but he is unable to do so, stating her spirit is refusing to return from the dead to be with him. Cordell kills Houngan, and both he and Kate are set on fire in the process she is immolated. As they escape, Susan and McKinney are chased by Cordell, who survived the fire while remaining ablaze. He chases them in a beat up police car, while they ride in an ambulance. They manage to throw an oxygen tank into the burning car before both crash. However, before Cordell can back up on the other disabled vehicle, the canister goes off, blowing up the car. Later, the charred corpse of Cordell is rolled into a morgue, next to the burned remains of Katie. While the lone coroner, who rolled Cordell into the morgue, is busy with his computer, the camera pans to the bodies, which shows Cordells hand moving over to hold Katies hand.Maniac Cop III was rated NC17 by the MPAA and upheld on appeal. It was released on home video in the United States by Academy Releasing. It premiered on HBO in 1993. ........
