Migrant's cell phone rings, tipping off Border Patrol to alleged smuggler

A ringing phone led to the apprehension of an Arizona man accused of smuggling illegal immigrants for profit. He was arrested near the U.S.-Mexico border.

Court records obtained by the Border Report state agents followed the car and ordered the driver to stop. When Martinez was asked if anyone else was in the vehicle, he said no. While they were questioning him, however, agents head a cell phone ringing in the trunk of the car.

Martinez was asked to open the trunk of the car and consented, but then claimed the trunk would not open, according to the criminal complaint filed Feb. 2 in U.S. District Court for the District of Arizona. The agents then asked if he would lower the backseats, so they could look inside the trunk, and Martinez allegedly said, "Oh, s---," when the person in the trunk became visible, records say.
