Inside a smuggling operation moving migrants across the US-Mexico border

The smugglers are brothers and run the business out of their family home, smuggling people into the US with the help of one brother's 14 year-old son. Makeshift ladders laid out in the backyard were the only real giveaway of the family business.

In most other places in Mexico, this might have just been some workers doing construction without the right truck for the job. But this car was driving right along the border wall in Ciudad Juárez, a city just south of the US-Mexico line, with El Paso, Texas on the other side -- a city where human smuggling abounds.
