Tony Stewart Runs Over Driver 2014-08-10 torrent

NASCAR driver Tony Stewart ran over a competitor, 20-year-old Kevin Ward Jr., during a confrontation at a sprint car race on Saturday night at Canandaigua Motorsports Park in New York. Ward was killed.

In the video above, via YouTube, you can see Ward apparently confronting Stewart on foot after Ward's car is run into the wall. He is struck, dragged, then thrown a number of feet. According to Ontario County Sheriff Philip C. Povero, Ward was dead on arrival at the hospital.

CMP posted the following to its Facebook page:

Tonight's racing events were suspended due to an accident. Please hold off on any speculation until we have further information to share.
Accidents are, obviously, common in the motorsports world. To shut down a track entirely following one is extreme, and if you look at the above photo you'll notice a major law enforcement presence. That's not standard for an auto racing accident, either. (Fox Sports confirmed law enforcement is looking into the incident.)

Here's how alleged eyewitnesses are telling what happened. Keep the usual caveats about things you hear on the Internet in mind, but the number of people who saw it happen—and their previous track records for motorsports reporting—suggests the worst.
