From azcentral.com:
U.S. Border Patrol agents in southern Arizona say they’ve rescued a 6-year-old Costa Rica boy who was abandoned by a smuggler in the desert.
Ajo Station agents say they found the boy west of Lukeville and just north of the Arizona-Mexico border on Tuesday evening.
The boy told agents he was on his way to see his parents in the United States and the smuggler told him that the Border Patrol would pick him up.
