The Real Version:
Apparently, Sonny Graham never saw those movies. Graham was a 50-something South Carolina businessman who needed a heart transplant, and while he didn't get it from an executed serial killer, the donor did experience a tragic and unnatural demise. The heart came from Terry Cottle, a 33-year-old man who shot himself in the head after his wife dumped him because he wasn't making enough money. You've probably guessed by now: A decade later, Graham ended up doing the same thing, using the same method.
Over the same woman.
After recovering from the transplant in 1995, Graham wrote a thank-you letter to the donor's widow, Cheryl Cottle, unaware that she and Terry were suicidally estranged at the time. One thing led to another, and a few years later Sonny and Cheryl were married. The couple seemed blissfully happy ... until they didn't. In 2008, amid serious financial and romantic troubles, Graham stepped into his backyard shed, put a shotgun to his throat, and pulled the trigger. That is not the act of an uncommitted or uncertain man. That is the hardest you can possibly kill yourself. So either the movies had it right all this time and body parts are haunted by their previous owners, or else the divorce laws in South Carolina really, really suck.
