A grand jury's decision to indict all six officers charged in the death of Freddie Gray, who died of injuries suffered in police custody, allows the state's attorney to press ahead with the most serious charges despite criticism that she was part of an "overzealous prosecution."

The indictments announced Thursday were similar to the charges Baltimore State's Attorney Marilyn Mosby announced three weeks ago. The most serious charge for each officer, ranging from second-degree "depraved heart" murder to assault, stood, though some of the lesser alleged offenses changed.

Attorneys for the officers have said in court documents that they're the victims of an "overzealous prosecution" riddled with personal and political conflicts of interest. At a minimum, they said, Mosby should be replaced with an independent prosecutor.
