Border Patrol agents are reporting the discovery of a huge amount of meth hidden inside a big rig on the South Texas border. Officers inspected a trailer loaded with stainless steel scrap metal that was crossing the World Trade Bridge at Laredo on Saturday. A K-9 and an imaging system helped agents find more than 900-pounds of meth inside the trailer. The drugs had an estimated street value of more than 18-million-dollars. Agents arrested the 33-year-old man from Mexico who was driving the truck.
