Tom Weekes, a Boise resident, told the Associated Press he attended the event with his 12-year-old son. They were a few feet away when the car struck the crowd. 

"My son and I were the last two people he missed," he said. "There was a group of kids to the right of us and he hit every one of them."

Justin King of Nashville, Tennessee, said he heard the crash and immediately rushed to the scene. "You could hear the screaming," he told the AP. "There were people's shoes that went flying. There was at least one youngster, less than 10, he was kind of unconscious."

King said 400 or 500 vehicles showed up for the car show and participants were peeling out for crowds who lined up outside the event to watch. "People like to show off when they leave these events," he said.

The Boise Police Department says preliminary information indicates the driver accelerated rapidly and lost control while leaving the event, crashing into several pedestrians on the sidewalk.

The driver is cooperating with the investigation and his Porsche was featured in the car show, according to police.

Police say an investigation into the crash is underway and will be forwarded to prosecutors for possible charges.
