NEW YORK --
Westchester County police were involved in the fatal shooting of a Mount Vernon police officer in downtown White Plains Friday afternoon.
White Plains Public Safety Commissioner Frank Straub told a news conference that the victim of the shooting was a Mount Vernon police officer. The officer's name wasn't released, so that his family could be told first.
Police said two men were involved in an argument outside 85 Court St., a district office of the county Department of Social Services, when one of them pulled out a gun and possibly fired a shot. The noise drew the attention of officers inside the building who came out and ordered the armed man to drop the gun, police said.
