BBC News reports Baltimore's top prosecutor says she plans to file criminal charges against six officers in the case of Freddie Gray who died in police custody. State prosecutor Marilyn Mosby said the death of the 25-year-old black man was a homicide, and his arrest was illegal. The charges range from second-degree murder to assault. Protesters cheered as she made the announcement. Gray suffered fatal spinal injuries while in custody, sparking protests that turned violent. "The findings of our comprehensive, thorough, and independent investigation coupled with the medical examiner's determination was a homicide... has led us to believe that we have probable cause to file criminal charges," Mosby told a news conference.
