Nasa car Stonestreet Stewart will be back on the track for his first race since this now infamous incident three weeks ago. You may remember this. He hit and killed a fellow driver after weeks in seclusion Stewart came to the cameras frying showing a side of himself we rarely get to see and gio Benitez is on the story. Reporter: This morning an emotional Tony Stewart is trying to push past the crash that killed 20-year-old racer Kevin ward Jr. On a dirt track in upstate New York. This has been one of the toughest tragedies I've ever had to deal with both professionally and personally. This is his first public appearance following the accident. That video still hard to watch. Ward getting out of his car after an initial accident apparently waving his hand at Stewart when moments later his car strikes and kills ward. This is a satness and a pain that I hope no one ever has to experience in their life. Reporter: Now three weeks later Stewart is practicing for tomorrow's sprint cup race and the NASCAR champ says he will try to meet with his family. I want his father, and his mother Pam and his sisters Christie and Kayla and Kaitlyn to know that every day I'm thinking about him and praying for them. Reporter: The driver phone for his hot temper on the track now subdued off it not taking questions from the press and returning to his car, number 14, for the first time in tomorrow's race at the Atlanta motor speedway. Stewart has not been criminally charged. Investigators say so far there's no evidence that he should be. But this morning, sports analysts wonder should a grieving Stewart race at all? The fact that the police have not yet completed their investigation and yet he's coming back to the track, it just seems wrong. Reporter: For "Good morning America," gio Benitez, ABC news, New York.
