A woman walks past the border fence between Mexico and the U.S. and near the site where a 16-year old boy was shot at by a U.S. Border Patrol agent Wednesday night in Nogales October 12, 2012. A U.S. Border Patrol agent shot at suspected drug smugglers who were hurling rocks from Mexico across the border into Arizona, the agency said on Thursday, and Mexican authorities said one of them was killed.
