Hours after thousands of black men took to the streets of St. Louis for a "Call For Oneness," a march to end black on black violence, 16 year old Shirlene Williams was gunned down outside a gas station. Shirlene, a high school freshman, and a 21 year old cousin stopped at BP gas station when shots rang out. Both Shirlene and her cousin were shot in the head. Her cousin remains listed in critical condition. Speaking of his sister, Antwawn McGee said "she was good...always used to say that she'd be the first one of going to college and be somebody."
