Brandie Weiler says her daughter is a true hero after saving her little sister from a carjacker. 

Weiler said she got out of her van to check on a driver who was in a car accident and call 911 when the man driving the other vehicle got out and tried to enter her van with her two daughters inside. 

But Maddie Weiler, 12, wasn't going to let him drive them off without a fight, especially with her little sister Mollie in the back seat.
