A grand jury could begin hearing evidence Wednesday in the case of an unarmed teen shot dead by police in a St. Louis suburb. The grand jury will decide if there's enough evidence to move forward with charges against Ferguson Police Officer Darren Wilson. Eighteen-year-old Michael Brown was unarmed when he was shot at least six times and witnesses say he had his hands in the air. Police however, say Wilson fired the shots during a struggle for the officer's weapon. The shooting sparked more than a week of protests and looting in the community of Ferguson.
