Human smugglers are going to extraordinary lengths to smuggle people across the U.S.-Mexico border. 

Adam Housley reported the number of people caught hiding in the trunks or crevices of vehicles crossing the border increased 50 percent in 2014 from 2013. 

"These smugglers have no regard for human life, all they want to do is make money off these people that they're smuggling," CBP Tucson Sector Chief Patrol Agent Manuel Padilla stated. "As our operations evolve, as we continue to get better identifying the smugglers, identifying the networks, they revert to different tactics that may have been successful in the past."

Housley added that in some cases, smugglers stuff as many as four people in the trunks of cars to come across the border.
