The two Mexican couriers were hauling a tractor-trailer full of cash: $3 million collected for drugs sold on the streets of Chicago. Juan Gonzalez and David Zuniga were driving their rig through Indiana in October 2011, transporting the money to Mexico. As they stopped to fix a flat tire, three members of the Gangster Disciples, Chicago’s biggest street gang, held them up at gunpoint.
Just before sunset on April 10, 2006, a DC-9 jet landed at the international airport in the port city of Ciudad del Carmen, 500 miles east of Mexico City. As soldiers on the ground approached the plane, the crew tried to shoo them away, saying there was a dangerous oil leak. So the troops grew suspicious and searched the jet.
