now giardano is saturated with guilt. it s painful how i feel like i didn t do what i promised i was going to do. and she trusted me, she believed in me. it wasn t your fault. you couldn t have stopped this from happening. if i was there, she probably would have been here. and she would probably do way more than what i m doing right now. she was just such a wonderful person. reporter: keyla s step dad was shot in the arm and in the mayhem was separated from the rest of the family. keyla was shot in the torso, the bullet exiting out her back, her uncle said. i can t imagine being on the ground, first my uncle, first my family. and just being there alone, scared.
