Tribal police discovered 27 undocumented immigrants packed inside a van during a traffic stop. The van was stopped Sept. 28 because it was weaving on U.S. 64, said Hugo Martinez, a supervisory special agent with the U.S. Immigration and Naturalization Service in Albuquerque. He said the group - 25 men and two teen-age boys, all from Mexico - were headed from Phoenix to Atlanta. "They were all just piled on top of each other," Martinez said. "They were just being treated like logs." Martinez said INS agents would determine if they should file criminal charges against anyone in the group. Otherwise, most would be sent to El Paso, Texas, for voluntary departures into Mexico.
