Border Patrol agents assigned to the checkpoint on Interstate Highway 35 north of Laredo, Texas uncovered a smuggling attempt when they found 47 illegal immigrants concealed in a trailer.

On September 20, the event unfolded when agents encountered a blue Freightliner tractor pulling a white trailer, with only one visible occupant.  During the primary inspection of the driver, a service canine alerted to the odor of concealed humans. 

The tractor-trailer was referred to secondary and further inspection revealed 47 individuals from the country of Mexico illegally present in the United States.    

The driver, a United States citizen, along with the illegal immigrants were placed under arrest and processed accordingly.  All of the individuals were evaluated and did not require medical attention.  The vehicle was seized by the U.S. Border Patrol.
