“The tragedy and the pain that brings us here today is extraordinary. It is unique. The lives that were taken from us are unique,” the president said to the around 5,000 people gathered at Marine Barracks in Southeast D.C. “What troubles us so deeply is how this senseless violence that took place in the Navy Yard echoes other recent tragedies,”

Lance Corporal Cody S. Schoenfelder of Huron, S.D. suffered a self-inflicted gunshot wound on Friday and died early Saturday morning, according to a statement from Captain Jack Norton, the public affairs officer for the Barracks.
