The father of the driver run over and killed by Tony Stewart tells The Syracuse Post-Standard that ``there's no reason for'' the crash that led to his son's death.

Kevin Ward Jr. was sent into the wall when his car was bumped by Stewart's in a dirt-track race on Saturday night. Ward got out of the car and walked onto the track, where he was hit by Stewart.

Kevin Ward Sr. told the newspaper that, ``the one person that knows what happened that night is possibly facing 10 years in prison. Is he going to say what he done?''

When the 20-year-old Ward got out of his damaged car, he walked on the track and appeared to point at Stewart. Other cars drove past him, but Stewart's right-rear tire appeared to hit him and drag him along the track.

``Apparently, Tony Stewart was the only one driving out there who didn't see him,'' Ward told the newspaper.

No charges have been filed against Stewart, but they are still possible.
