CANANDAIGUA, N.Y. — Kevin Ward Jr. died of ''massive blunt trauma'' according to the Ontario County coroner, said county sheriff Philip Povero during a news conference Monday afternoon.

"The autopsy was conducted today. The Ontario County coroner has stated cause of death was massive blunt trauma," Povero said.

Ward Jr., 20, was struck by Tony Stewart's car during a sprint car race Saturday night at Canandaigua (N.Y.) Motorsports Park after Ward exited his car and walked down the track under a caution period. Ward's body was thrown and he was fatally injured.

Povero said the sheriff's office had two videos and are seeking more videos as the investigation continues.

"No timelines set on this. We want to complete this investigation as quickly as possible ... At this time, there are no facts that exist that support any criminal behavior or conduct or support any probable cause in this investigation," he said.

"There's no fact right now that would support someone committed a criminal act."

Povero also indicated his office had been in contact with Stewart on Monday and the three-time Sprint Cup driver remained available and was cooperative.

Funeral arrangements for Ward Jr. were announced earlier Monday. Visitation will be held noon-4 p.m. ET and 6-9 p.m. ET, Wednesday at Trainor Funeral Home in Boonville, N.Y., according to owner Carl Trainor. The funeral will be Thursday at 11 a.m. ET, though Trainor said a venue has not yet been chosen.

Poero refused to talk about toxicology reports at the request of the district attorney's office. He indicated those officers investigating are trained to investigate motor vehicle crashes.

He also said he was not aware of any in-car camera in Stewart's car.

Earlier Monday, Mike Arning, director of communications for Stewart-Haas Racing, told USA TODAY Sports that Stewart's sprint car schedule was indefinitely suspended and he was still mulling whether he would return to NASCAR this weekend at Michigan International Speedway.

"The decision to compete in this weekend's NASCAR Sprint Cup Series event at Michigan will be Tony's, and he will have as much time as he needs to make that decision," Arning said in an email to USA TODAY Sports.

"It is still an emotional time for all involved, Tony included. He is grieving, and grief doesn't have a timetable."

Arning confirmed Stewart had canceled a planned sprint car event for Saturday in Indiana, and any racing beyond NASCAR "won't resume until further notice."
