The trial for the fourth Baltimore police officer charged in Freddie Gray's death is winding down.

FOX's Tonya J. Powers is on the case:

Lieutenant Brian Rice is on trial in the death of Freddie Gray whose broken neck in police custody provoked riots last year in Baltimore.

Rice is the highest-ranking of six officers charged in Gray's death.

An assault charge against Rice was dismissed but he still faces charges of manslaughter, reckless endangerment and misconduct in office.

Baltimore circuit Judge Barry Williams alone will decide whether to convict or acquit Rice, who waived his rights to a jury trial.

Judge Williams has already found two other officers who opted for bench trials in Gray's death not guilty.
