The 24-year-old extra is not a stuntwoman and was in her own car when the accident happened on Wednesday night.

"The vehicle was being towed by another vehicle," fellow extra Blaine Baker told Chicago station WLS. "The cable between the two vehicles broke. It whipped around and sliced through the woman's car and sliced through her skull, apparently."

He added that the car was then dragged along a center divider for about half a mile, "grinding the side of the car off."
