ST. LOUIS — The verdict in the trial of a man charged with killing an officer is expected Thursday. Caleb Campbell is accused of killing Brooklyn, Illinois, Police Officer Brian Pierce Jr. in August.

Pierce placed stop sticks on the McKinley Bridge to prevent a vehicle from fleeing the police. Prosecutors claim Campbell was driving the car when he hit and murdered Pierce.

Campbell is charged with first-degree murder and other offenses. Pierce’s family wants him to serve his life in jail without the possibility of parole.
