SAN DIEGO (MCT) — Federal authorities have linked a high-ranking Mexican organized crime member to two of the largest drug tunnels ever discovered under the San Diego-Tijuana border, according to a 13-count indictment announced Wednesday that details a far-flung operation that allegedly moved tons of marijuana across the border.

Jose Sanchez-Villalobos, 49, is the highest-ranking member of the Sinaloa drug cartel ever charged in connection with the construction of underground tunnels, according to federal prosecutors in San Diego.
