Texas Border Agents Intercept Travel Trailers Smuggling 74 Illegal Aliens More than 70 illegal immigrants being smuggled into the United States in travel trailers were apprehended by border agents conducting traffic check operations in Texas, officials announced on Thursday. U.S. Customs and Border Protection (CBP) said in a statement a total of 74 illegal aliens were discovered in two large travel trailers on Monday at an immigration checkpoint on Interstate 10 in Sierra Blanca—about 85 miles east of El Paso. In addition, border agents also apprehended three U.S. citizens who have been accused of smuggling. Two of the men were turned over to Texas police for questioning. The third American believed to be involved in the scheme has been identified as a juvenile. He was released again due to his age, the service said.
