First we got this from Alert DC: Due to police activity the 3000 block of 14th St. NW is closed Northbound & Southbound.and 14th & Irving St. NW is blocked. Columbia Heights Metro Station(Green Line) is closed on the South side
And then saw this report from DCist: http://dcist.com/2009/06/double_shooting_at_columbia_heights.php.
Apparently a double shooting at the Metro. Guessing a Jim Graham update will come later this evening.
