Could a Ghost Kill a Person or a Demon Kill

Our next question comes from megan strickland, who says, living in tennessee, i've heard the story of the bell witch so many times i've lost count. For those not familiar, the incredibly short version is that a ghost named t haunted the bell family, and ultimately killed the patriarch, john bell, by poison. Jimmy and tom: What are your thoughts on this story and what cald it mean from a theological standpoint of a ghost or demon? Is this even remotely possible?
