Strong odor leads to California drug bust

Authorities pulled over a tractor-trailer for a traffic violation. The strong smell of marijuana helped them discover $45 million worth of drugs in the back of the truck.

An "overwhelming odor" led investigators to about 20 tons of narcotics stashed in pallets in the back of the truck, including about 38,000 pounds of marijuana, 2,700 pounds of cocaine and 67 pounds of methamphetamine, the sheriff's office said in a statement.
