Suffolk County District Attorney Dan Conley released video Friday showing Boston Police Officer John Moynihan being shot in the face last month in Roxbury.

Gang unit officers with Moynihan fatally shot the suspect, 41-year-old Angelo West. Police said West continued firing at them as he tried to run away from a traffic stop. 

The Suffolk County District Attorney's office released the video at a Friday press conference where Conley and Boston Police Chief William Evans spoke.
