WATCH: Prince George’s County Police Officer Found Not Guilty in Assault Trial

A judge found a retired Prince George’s County police officer not guilty of assault Thursday morning.

In February 2012, Officer Donald Taylor and his partner saw two men they thought were about to rob a gas station in Brentwood, Taylor said. When they approached the men, 19-year-old Ryan Dorm struggled with the officers and ran away.

Taylor originally said that when he caught Dorm, the teenager grabbed his gun, causing it to fire.

Police arrested Dorm, who spent almost four months in jail.

Then surveillance video was found that showed Dorm never reached for the gun. Charges against Dorm were dropped, and he sued the police department. Officer Taylor was suspended and charged with assault.

Dorm testified Tuesday that there was very little time between when he turned around and when the officer hit him.

Taylor testified Wednesday he didn’t know he had his gun in his hand when he hit the suspect in the head. He said he acted in self-defense.

The defense offered several expert witnesses who told the judge Taylor acted within reason.
