A Texas Department of Public Safety trooper stopped a white Volvo truck on Interstate 35 in Webb County on May 18 during Operation Lone Star and discovered 20 undocumented immigrants—16 adults and 4 minors from Mexico and Guatemala—hidden in the truck's sleeping compartment. The driver, 25-year-old Miguel Angel Velazquez Chavez, a Mexican national, fled on foot but was arrested and charged with evading arrest and smuggling people. All 20 migrants were turned over to U.S. Border Patrol.
