A Laredo lawyer was arrested last week by the U.S. Border Patrol on charges of immigrant smuggling after he allegedly picked up a pair of Hondurans abandoned by their guide along a South Texas highway.

According to a criminal complaint affidavit obtained by The San Antonio Express-News, an off-duty Border Patrol agent was traveling north on U.S. 83 near Cotulla when he reported seeing two men he believed to be undocumented immigrants get into 71-year-old Armando Treviño’s Toyota sport-utility vehicle.
