Jeff Gluck of USA Today provided a statement from the Ward family:
On Aug. 14, per Pockrass, Ward's family spoke further on the accident:
"Tony races every weekend," Kevin Ward Sr. said. "Well I know my son will never get to race again. ... He took a very, very big part of my family's life."
"We want justice for our son," Ward's mother Pamela said. "That's what we want. ... I don't feel Tony meant to kill my son. But his actions killed my son. I think he lost his temper."
Ward died on Aug. 9, 2014, while competing in an Empire Super Sprints series dirt-track race at the Canandaigua Motorsports Park in New York.
During the race, Ward and Stewart were side by side at a turn when Ward spun out. While the race was still going on, Ward exited his vehicle to confront Stewart as his No. 14 car was coming around the turn.
Stewart struck Ward, with the impact killing the 20-year-old. Ontario County Sheriff Phil Povero confirmed the cause of death was blunt trauma, according to ESPN's Marty Smith.
Stewart released a statement immediately after the accident, via NASCAR:
A grand jury looked into charges of criminally negligent homicide and second-degree manslaughter against Stewart, but determined not enough evidence was present for an indictment.
Ontario County District Attorney Michael Tantillo said in the subsequent press conference that the grand jury was presented with two different videos of the incident that were enhanced to provide as much detail as possible, per USA Today.
"The videos did not demonstrate any aberrational driving by Tony Stewart until the point of impact with Kevin Ward, at which point his vehicle veered to the right up the track as a result of the collision," Tantillo told the press. "Prior to that, his course was pretty straight."
In their lawsuit, the Ward family counters that Stewart could've avoided the accident, per Pockrass.
"Stewart could have easily acted reasonably and with prudence to avoid striking Ward, just as all other drivers had done as they passed Ward during the yellow caution flag," they argue in the lawsuit. "Stewart acted with disregard for Ward's life and safety by driving his vehicle in a manner that would terrorize Ward and thereafter strike, severely injure and kill Ward."
