FALFURRIAS – Border Patrol has a warning for those considering smuggling people across the border illegally.

The warning comes after agents found 12 people in the country illegally hidden in the back of a tractor-trailer over the weekend.

“People can perish very, very quickly, especially during this heat,” says RGV Sector Chief Manuel Padilla Jr. 

KRGV’s Cecilia Gutierrez has more on how the agency is combatting human smuggling with ‘Operation Big Rig’.
