A newly discovered drug tunnel on the Mexican border in Nogales, Ariz., is a record-breaking 481 feet long, according to the Arizona Republic. Immigration and Customs Enforcement officials said the tunnel extended from a house in Nogales, Sonora, to a house in its Arizona twin city. It was being used to smuggle marijuana and other drugs into the U.S., ICE officials said.
Nogales has been the epicenter for cross-border drug tunnels for years. U.S. authorities have found 100 drug tunnels in that city since 1990, more than any other location along the 2,000-mile United States-Mexico border. The Nogales, Ariz., house had been under surveillance by a multiagency task force created in 2012 to focus on drug tunnels. Authorities found a half pound of heroin and 46 pounds of marijuana inside, and they seized another 590 pounds of marijuana from a vehicle seen driving away from the house.
