The first trial for six Baltimore police officers charged in the death of Freddie Gray will be held Nov. 30, and the other trials are set for early next year.

Judge Barry Williams decided Tuesday that Officer William Porter will go on trial first. He is accused of failing to provide or request medical care for Gray and not securing him safely in a van. Porter faces charges of manslaughter, assault, reckless endangerment and misconduct in office in the death of Gray, a black man who died after being injured in police custody.

Prosecutors said they intend to call Porter as a witness against at least two other officers. The judge ruled earlier this month that each officer will get his or her own trial and that they will be held in the city.
