After the king of tunnels, El Chapo, escaped a high-security prison last month, Mexican police officials found a drug tunnel linking the United States and Mexico on July 30. Sunday was the first time reporters were able to get a look at the 404-foot long, unfinished tunnel that may have been built by the Sinaloa cartel to smuggle drugs into the U.S., according to CNN. The tunnel was found after the authorities were tipped off, which ended with them finding a well-lit, well-ventilated tunnel that starts in Tijuana and finishes just two blocks short of the border.
