This witness video shows the moments leading up to the sprint race track crash involving NASCAR driver Tony Stewart, which killed Kevin Ward, Jr.
During the 14th lap, Stewart pushed Ward's car off the track. Ward exited his car and walked out between other racing vehicles to what appears to be an attempt to confront Stewart.
Stewart's spokesman announced that he will not compete in today's Cheez-It 355 NASCAR race and that the decision was Stewart's.
