A 6-year-old Dallas girl riding her bike was hit by a vehicle and killed Friday night.
A sport utility vehicle struck the girl on the U.S. 67 frontage road near Wedgecrest Drive just before 7 p.m.
A witness who smashed into the SUV in the crash said the girl was riding her bike in an alley and couldn't stop before the street.
"As she was coming across the alleyway, she tried to stop the bicycle with her feet, but she couldn't stop, and by the time she got into the middle of the street, she was hit by the black car," James Wilson said. "I tried to assist the little kid as best I could. I don't know CPR, so made her lay down, stay still. I used the shirt that I have on to wipe the blood off her and I asked a cousin to ride home and get assistance for her."
The girl was taken to Children's Medical Center of Dallas, where she was pronounced dead.
Dallas police are investigating the accident but don't expect to file any charges.
The driver that struck the girl was not speeding or doing anything wrong and remained at the scene after the crash, police said.
