A circuit judge ruled Wednesday that the case against six Baltimore police officers charged in the arrest and death of Freddie Gray will go forward in separate trials, with Baltimore State's Attorney Marilyn J. Mosby remaining at the helm of the prosecution.

During a day of hearings in a downtown courtroom, Judge Barry Williams swiftly sliced through complex legal arguments in the first motions hearing. In three key rulings issued from the bench, he refused to dismiss the charges or recuse Mosby and decided that the case should be split to ensure that each officer gets a fair trial. 

Williams said that trying the officers together would not be "in the interest of justice" because key evidence that's admissible with regards to one officer may be inadmissible for another. The officers are charged with a range of offenses, from murder to misconduct, as each played a different role in Gray's arrest and transport, the Baltimore Sun reports.
