How did this manmade smuggling tunnel supposedly go undetected for so long?
A manmade smuggling tunnel with electricity and ventilation from Ciudad Juarez to the US side of the border in El Paso was recently discovered.
A Border Patrol spox thanked Mexican law enforcement as well as US CBP and local authorities in Texas for working together to discover the sophisticated smuggling operation.
The tunnel is six feet tall and four feet wide, according to CBP.
