BALTIMORE — (CNN) — Baltimore Police Lt. Brian Rice was found not guilty on all charges tied to the death of Freddie Gray. Rice, the highest-ranking officer to stand trial over Gray’s death, had been charged with involuntary manslaughter, reckless endangerment and misconduct in office.

Judge Barry Williams issued the ruling.

Rice is the fourth of the six officers charged in the case to stand trial.

Earlier this year, officers Edward Nero and Caesar Goodson Jr. were acquitted on all charges in bench trials. The trial of officer William Porter ended in a mistrial in December after a jury was unable to reach a unanimous verdict on any of the four charges against him.
