Mass Grave Exposes Entrenched Trafficking in Thailand

Police in southern Thailand have found two more camps believed to have held human trafficking victims -- one containing a buried skeleton. This comes just days after officials announced arrests in connection with the grisly discovery of 26 bodies in a mass grave at another location. Officials suspect as many as 400 mostly ethnic Rohingya from Myanmar were being held for ransom at the remote camp near the Malaysian border. Steve Sandford reports on developments in the case.
