A 16-year-old teenage girl, playing a variety of chicken with her 17-year-old brother, accidentally ran over and killed him in an Arizona shopping mall parking lot, police said.

According to Mesa, AZ Police spokesman Ed Wessing, Nicole Brock had dropped off her brother, Dwight Brock, Jr., at Superstition Springs Mall Saturday evening. Later, they started playing, with Dwight jumping in front of the car and the Nicole slamming on the brakes.

Sadly, the last time Dwight Brock tried to do that, Nicole was unable to stop in time and ran over him. He was rushed to a hospital in critical condition and later pronounced dead.
