NASCAR champion Tony Stewart struck and killed fellow driver Kevin Ward Jr. in a horrific accident Saturday at the Canandaigua (N.Y.) Motorsports Park. While we may never know what really happened between the two during the sprint car race, many Twitter users have voiced their opinions, including accusing Stewart of murder, as well as questioning Ward Jr.'s actions.

During the Empire Super Sprints race, Stewart sent Ward's car into the wall and Ward then jumped out to confront Stewart with the yellow, or caution, flag raised for all other drivers. Ward walked to the middle of the track and pointed towards Stewart’s car and was run over, dragged and then flung a great distance.

The Ontario County Sheriff Dept. reportedly stated that Ward Jr., 20, was pronounced dead on arrival at the hospital. No charges have been filed against Stewart, 43, and while he originally intended to race in NASCAR's Watkins Glen competition Sunday, he later pulled out.

Once the tragedy began to trend on Twitter, users offered their opinions as to who was to blame. Many pointed to Stewart, but others called out Ward Jr.

Before Stewart opted out of Sunday's race, many also questioned why NASCAR would even let him race.
