Two Guatemalan nationals have reportedly been shot dead along the U.S.-Mexico border in the latest in a spate of border killings by U.S. agents. The male victims were killed last week when a Texas Department of Public Safety sharpshooter fired from a helicopter on a pickup truck near the border town of La Joya. The incident is under investigation, with officials claiming the helicopter crew believed the truck was carrying drugs. The Guatemalan consul says both victims were seeking employment to support their children in Guatemala.
