A suicide during this weekend's NRA 500 at the Texas Motor Speedway will likely only add to the controversy behind the National Rifle Association's title sponsorship of the NASCAR Sprint Cup race. Kirk Franklin, 42, of Saginaw, TX, shot and killed himself in the infield of the track during late stages of the race Saturday night following an argument with other race fans.

According to a report from The Huffington Post, Franklin shot himself at 10:30 PM, and his body was found in the back seat of a pickup truck. Texas law prohibits guns at the racetrack, so it isn't clear how or why Franklin smuggled the gun in to the track in the first place.
