Police Chief Garry McCarthy says today that "what would have been, under any other circumstances, probably a fistfight between two 14-year-old girls because of an argument over a boy turned into a murder."
The shooting killed 14-year-old Endia Martin.
McCarthy says a .38-caliber gun stolen two weeks earlier from a car was used in the shooting yesterday. Two other teens may face criminal charges after authorities say they brought the weapon to the fight and tried to discard it after the shooting.
