The trooper who, while aboard a Department of Public Safety helicopter fired at a fleeing truck in Hidalgo County to disable it, has returned to work, the DPS reported Thursday.
Nine Guatemalan immigrants were hidden under a tarp in the pickup's bed. Three were wounded, two fatally.
Texas Rangers are investigating, although civil rights groups have called for an agency not associated with the DPS to do that. The Rangers are part of DPS.
