A District man was sentenced to 22 years in prison Friday for the 2010 slaying of a man who tried to break up a fistfight between two women.

D. C. Superior Court Judge Gerald I. Fisher sentenced Marcus C. Silver, 30, of the 1200 block of Rock Creek Ford Road NW, after a jury found Silver guilty of manslaughter while armed, assault with a dangerous weapon and other charges in connection with the March 20, 2010, shooting death of Shadawnchea Gardner, 26, in the unit block of Hawaii Avenue NE.

According to prosecutors, Gardner had accompanied Silver’s ex-girlfriend and another woman to Hawaii Avenue to get a video game from Silver.

Silver’s ex-girlfriend and his current girlfriend got into a fight, authorities said, and while Gardner was trying to separate the women Silver walked up and shot Gardner once in the back of the head.

Silver also shot at his ex-girlfriend, who was not injured, according to authorities.
