A 13-year-old girl is being hailed a hero for protecting her 5-year-old brother as gunfire erupted on their way to a candy store in New York. Miraculously, neither Mia nor Christian were shot as the gunman’s intended target collided with them. Mia’s first instinct was to shield her brother with her own body. Her father says she has always been brave and wants to be a New York cop when she is old enough. The entire family was at Yankee Stadium Sunday as guests of honor in the executive box.
