Trey Walters’ marriage was crumbling rapidly at a time when his family was grappling with serious financial and other challenges. He firmly believed that an evil entity or energy — introduced by his wife — was involved.“One night, I encountered a frightening spirit that entered my house … I knew a warlock was attempting to take me out, but I was unsure who, where, and what. I felt tormented. I could not function correctly,” he writes in his book, How I Lost My Wife to a Warlock.
