No officers will be charged in the killing of a man who confronted police with a BB gun in Washington last June.

The U.S. Attorney's Office for the District of Columbia announced Tuesday that its review of the shooting of Sherman Evans Sr. found that evidence supports the officers' account that they fired in self-defense.

Prosecutors say Evans himself called 911 to report an armed man in front of a building. When police arrived, they found Evans outside holding a weapon that turned out to be a BB gun.

The U.S. Attorney's Office's statement says the officers repeatedly ordered Evans to "drop the gun." It says they fired when Evans pointed his weapon at officers and started to move in their direction.

Prosecutors say narcotics were found in Evans' system.
