A U.S. Border Patrol agent opened fire on people throwing rocks from the Mexican side of the border, apparently killing a teenage boy. Sixteen-year-old José Antonio Elena Rodríguez was found dead from gunshot wounds, according to Mexican authorities. Border Patrol says they were responding to reports about smuggling when they saw two people abandon an amount of drugs and flee across the border back into Mexico Wednesday night. An agent opened fire after people started throwing rocks from the Mexican side and did not heed orders to stop.
