On a hot July day New York police are called to a site in Central Park where a body has been discovered. On examination, they find that every bone in the man's body has been broken, including his neck. Naturally suspecting violence and foul play, they call the coroner to perform an autopsy. On completion, everyone is stunned to find that the man died of hypothermia. He froze to death on one of the hottest days of the year. What's going on?

I'd always thought the answer was an urban legend, but reading this story (which was probably an unintentional case) makes me wonder.
