Karla Booker is held by friends Kiayla Coakley, left, and Briana Kirkham, at a candle light vigil in Comer Cox park for Andre Booker, Karla's older brother who was shot and killed at the park Wednesday. Nineteen-year-old Andre was a college student, the victim of retaliation for another murder, police said. He wasn't a suspect, they added, he just happened to be in the wrong place at the wrong time.
