Protesters took to the streets for a second night in St. Louis after holding a candlelight vigil for Vonderrit Myers, the 18-year-old black man who was killed by a white off-duty officer. Authorities say the officer returned fire after Myers began shooting, but Myers' family claims he was unarmed. The incident comes about two months after unarmed teenager Michael Brown was shot in nearby Ferguson, Mo., and has reignited protests over racism and excessive force by police in the area
