A 14-year-old Florida girl has been called a hero for protecting her little sister from a stranger with a gun. The drama began when a man suddenly appeared outside their home with a gun. The man knocked on the front door. Turning to leave, she turned around and opened the front door. For Leah Kissinger, protecting her four-year-old sister was a priority. She picked her up, took her to another room and hid. The family does not plan to press charges and hopes the man gets the help he needs.
