Decorated Boston Police Officer Released From Hospital After Being Shot

Officer John Moynihan was shot after he and five officers pulled over a driver.

The Boston Police Department described officer John Moynihan's condition as "serious but improving." He has been hospitalized since March 27 when he was shot just below his eye during a traffic stop.

The shooting suspect, Angelo West, was killed during an ensuing shootout with police.

Surveillance video shows officers approaching West's car after he was pulled over. As Moynihan, 34, approaches the driver's side, the video shows a flash and he falls to the ground. West, 41, then runs off while continuing to shoot at the other officers.

Boston Police Commissioner William Evans has described the shooting as "unprovoked" and said West had a violent criminal past.
