The attorney general's office did not say whether the 563-yard (meter) -long passage tunnel found in Tijuana actually reached U.S. soil.
The tunnel had rails, apparently used to push loads of drugs through. It was about 3 feet wide and 4 feet high, and was built about 23 feet (7 meters) under ground level
Prosecutors found over 2 metric tons of marijuana in packages at the house where the tunnel began on the Mexican side.
Also Monday, federal police said they found 4.2 pounds (1.9 kilograms) of methamphetamine hidden in a wheel of cheese at . . .
