After reviewing surveillance footage at the scene, CPB said the young boy was dropped by someone who was entering the country illegally, and several others were seen crossing over into the U.S.

"Responding Agents and EMS providing first aid to the child also reported gunshots near their position while tending to the child. Remarkably, the child is ok! Do not trust smugglers," 25th Chief of the United States Border Patrol Raul Ortiz warned.
The Chief also advised those in the area to cover.
