Man at NRA Nascar Events Kill Himself With Gun

The story started to emerge early today--man killing himself at a NASCAR event in Texas.  No details at all, except hint of drinking and/or an altercation.  Then it turned out it was the NRA sponsored NRA 500.  Okay.  Now we learn he shot himself in the head with a gun.  At an NRA event.  "Fort Worth police have said a man who was camping in the infield died of a 'self-inflicted injury' after getting into an argument with other campers. The incident happened late in the Sprint Cup race."
