The office of a Florida state attorney who is investigating the Trayvon Martin shooting plans to announce new information in the case at 6 p.m. ET Wednesday.
Earlier, a senior law enforcement source familiar with the Martin death investigation told CNN said that George Zimmerman would be charged.
Police say Zimmerman fatally shot Martin, a 17-year-old African-American, on February 26 in Sanford, Florida, after Martin began walking home from a convenience store. Zimmerman, who is Hispanic and was a neighborhood watch volunteer, had called 911 to complain about a suspicious person in the neighborhood. He was released without charges after claiming self-defense, but the case was referred to a special prosecutor as thousands converged on Sanford to join in protests calling for Zimmerman's arrest.
