CANANDAIGUA, N.Y. -- Ontario County Sheriff Phil Povero said Monday that the investigation is progressing into the deadly crash involving NASCAR star Tony Stewart at a dirt track in the Finger Lakes.
Stewart's car struck and killed Kevin Ward Jr. during Saturday night's race at Canandaigua Motorsports Park. Ward got out of his car before he was hit. Ward was 20 years old.
Povero said the autopsy on Ward was conducted earlier Monday, and the Ontario County Coroner ruled the cause of his death was massive blunt force trauma.
Povero said at this time, there are no facts that support any criminal behavior or conduct, or probable cause in the crash, but emphasized that the investigation is open.
Investigators have now reviewed two videos of the incident. Povero said they show two different angles of Ward walking on the track after a crash at turn two on the 14th lap, and then being hit by Stewart's winged sprint car.
"From what I saw, Tony did everything in his power to turn down away from Kevin to avoid him," said sprint car driver Cory Sparks.

Sparks was just a few cars behind Stewart during Saturday's race. He said videos that have been posted online do not give an accurate picture of what happened.
"People say that they heard the engine rev up and he gassed it. In a sprint car, the only way to steer is you steer with the rear wheels as much as you do the steering wheel. In my opinion, what he did was he gassed it to turn down away from him," said Sparks.
Sparks also said drivers are very limited with the amount they can see out of the right side of the car.
"Kevin was wearing all-black. A black fire suit, a black helmet, which in normal situations isn't a big deal, they are to go with the colors of your car. It was tragic accident and a mistake was made," said Sparks.
Povero said investigators have spoken to Stewart twice, and they are continuing to speak with other racers, track staff, and those in the stands to figure out exactly what happened.
"I think that the biggest thing is to remember Kevin Ward as a great race car driver, not a victim of Tony Stewart," said Sparks.
Calling hours for Ward, a native of Port Leyden in Lewis County, are set for later this week.
Stewart did not race Sunday in Watkins Glen and has canceled plans to run another sprint car event this coming weekend in Indiana.
