Authorities say rival gunmen started shooting at each other in a crowded downtown nightlife district in Alabama’s capital city, killing two people and injuring 12 others. Montgomery Police Chief James Graboys said three of the injured in Saturday night's shootings were hospitalized with life-threatening injuries. Police were called around 11:30 p.m. to what Graboys described as a “mass shooting" in which two rival parties were firing at each other in the middle of a crowd without regard for the people around them. Graboys said investigators were combing through evidence and interviewing potential suspects, although no one had been charged early Sunday.
