Six Baltimore Police officers were indicted on various charges by a grand jury on 21 May in the death of Freddie Gray.

The indictments were announced in a late-afternoon press conference by Baltimore State's Attorney Marilyn J Mosby almost three weeks after she announced criminal charges against the six. According to the Baltimore Sun, some of the charges in the indictment were different than those announced on 1 May.

Officer Caesar R Goodson, who drove the police van that transported Gray on 12 April, continues to be charged with second-degree depraved heart murder, along with manslaughter, second-degree assault, vehicular manslaughter (gross negligence, vehicular manslaughter), criminal negligence, misconduct in office and reckless endangerment.

His death a week later sparked protests in Baltimore and throughout the country. The protests in Baltimore turned violent with a night of rioting and looting that led to the National Guard being called in.
