A woman cries after identifying the body of a loved one, who died in a commuter train crash, at the morgue in Buenos Aires, Argentina, Thursday Feb. 23, 2012. Wednesday's commuter train crash killed dozens and sent hundreds to emergency rooms. A federal judge was leading an investigation into what caused the rush-hour commuter train to slam into a barrier at the end of the track at a downtown station, crumpling cars around hundreds of riders.
