The Bell Witch's Revenge

My imagining. In the Bell Witch case, John Bell died. The entity's antics focused on John for a while up to his death. Most believers think his failing health was the entity's fault. It wore him down.
His death itself was the result of taking something other than his medicine. The rumor was the "Witch" replaced it with a harmful agent in the family's medicine holding.  If this is true, it would have been one of the minute terminal hauntings recorded.
