U.S. finds major cross-border tunnel used to smuggle drugs

SAN DIEGO — A large haul of drugs, including opioids, methamphetamine and cocaine, being smuggled from Mexico to California was seized from a cross-border tunnel equipped with ventilation, lighting and an underground rail system, authorities said Tuesday.

The tunnel connected warehouses in Tijuana and San Diego, extending about 2,000 feet with an average depth of 31 feet and width of 3 feet, according to the San Diego Tunnel Task Force, an investigative team made up of several federal agencies.

Investigators believe the tunnel existed for several months “due to the advanced construction observed in several portions.”

Authorities seized more than 2 tons of a variety of drugs, a departure from earlier discoveries that consisted largely of marijuana. The discovery of the tunnel on March 19 netted about 1,300 pounds of cocaine, 86 pounds of methamphetamine, 17 pounds of heroin, 3,000 pounds of marijuana and more than two pounds of fentanyl.

The tunnel was built near a vaunted double-layered border wall constructed under President Donald Trump’s watch, illustrating the limitations of such barriers against sophisticated drug smuggling organizations. While border walls built under Trump go underground to deter digging, they are not nearly deep enough to stop the most advanced secret passageways.

The discovery marked the first time that five types of drugs were found in a single tunnel in San Diego, a magnet for Mexican cartels for its clay-like soil and abundance of industrial warehouses on both sides of the border that give cover for trucks and heavy construction equipment.

No arrests were made but authorities said the investigation was open.
