Tony Stewart hits and kills another driver during a dirt track race - WARNING: GRAPHIC CONTENT

WARNING: GRAPHIC CONTENT

NASCAR superstar Tony Stewart drove his  race car into another driver Saturday night … sending the man to the hospital  where he was later pronounced dead. Kevin Ward  Jr. had gotten out of his #13 car after an on-track accident involving  Stewart during a sprint car race (dirt track) in Canandaigua, NY.

            20-year-old Ward appeared angry after the wreck and attempted to  point and yell at Stewart as he drove past in his #14 car on the next lap -- but  Tony ended up hitting him … sending Ward flying down the track.
Hours  after the accident, cops said they were investigating Ward's death as an  "on-track" incident, and not a criminal matter. But it could turn into one if  the evidence warrants.
