Killer Hat?

The Los Angeles Times recently reported a teenager in Georgia was decapitated by a Six Flags amusement park ride after leaping a fence into a restricted area. While no one knows what motivated the fellow, witness apparently reported he went in pursuit of a hat that had fallen off.
While the Riff is truly saddened by the death of any teenager, he can 't help but wonder WHAT KIND OF HAT WAS IT?
We're putting even money on the hot hat of the moment -- the stingy brim fedora.
