A third police officer is found not guilty by a judge in the death of Freddy Gray in Baltimore.

FOX's Tonya J. Powers reports: 

Judge Barry Williams says prosecutors failed to reach burdens of proof for each of the charges against Lieutenant Brian Rice. Manslaughter, reckless endangerment and misconduct in office.

Rice was the fourth and highest-ranking of six officers to go on trial.

Defense attorney Warren Alperstein says it's time for the state to rethink the remaining trials:

(Alperstein) "There are no more theories to put forth to a judge or jury for that matter, and the state really has to think hard about not prosecuting anymore."

Rice is now the third officer to be acquitted, another trial ended in a hung jury. A retrial is set for September.
