(by John Wilkens, Los Angeles Times) – For the last seven years, the Confined Spaces Entry Team (who call themselves the tunnel rats) have been going underground to locate, map and seal off the tunnels used by cartels to smuggle drugs from Mexico to San Diego and beyond.
Theirs is a little-known part of the high-stakes hide-and-seek game that plays out daily along the border. While much of the attention…has been focused on…what happens aboveground, more than 80 tunnels have been found in California and Arizona since 2011.
Some have been almost 3,000 feet long and contain tracks for motorized carts, as well as lights, elevators and ventilation. One ended underneath a house in Calexico built just to provide cover for the tunnelers.
Warehouses constructed close to the border in Otay Mesa and Tijuana provide camouflage: an out-of-view place for a tunnel to start and another for it to end.
The area’s clay soil is particularly good for tunneling — not too soft or too hard.
“This,” said Lance LeNoir, gesturing at the warehouses and the ground between them, “is what makes San Diego grand central for the long, sophisticated tunnels.”
LeNoir is an operations officer for the Border Patrol. He heads the five-member tunnel rats, and he was standing one recent weekday morning near what’s known in law enforcement circles as the Galvez tunnel.
Discovered in December 2009, it stretches 762 feet from a warehouse in Tijuana toward a warehouse on the U.S. side, just west of the Otay Mesa Port of Entry.
The tunnel is 6 feet tall by 4 feet wide, large by tunneling standards, and 100 feet below the surface in some spots, sloped to allow groundwater to flow out of the way.
The traffickers had been working on it for about 18 months and had not yet finished when it was discovered after a tip from an informant. A dozen people were arrested inside.
Now what’s left of the tunnel, about 30 feet, is used for training by the tunnel rats. They practice rescues and test their equipment there.
The tunnel rats borrow their name from the Vietnam War forces who went underground in search of enemy fighters, sometimes engaging in hand-to-hand combat.
“They had it a lot tougher than we do,” LeNoir said. “We use the name in homage to them.”
Several of the team members are military veterans, and their uniforms resemble those worn by soldiers: camouflage pants, helmets, vests, guns.
Team members volunteer for the assignment, and to join they first have to crawl through a two-foot wide pipe for about 20 yards. That helps weed out agents who are claustrophobic.
Increasingly, the tunnels are getting narrower and shorter — they’re quicker to build that way, and cheaper. One found last year was only 14 inches wide.
Getting inside the Galvez tunnel is simple by comparison. Visitors climb down 70 feet of metal ladders, installed in a concrete shaft built after the underground smuggling route was discovered. It intersects the tunnel in a spot between the primary and secondary border fences.
“These tunnels wouldn’t meet any mining or construction standards that we are familiar with,” LeNoir said. If wood is found inside shoring up the walls and roof, it’s not because of a devotion to structural integrity, he said, but because a collapse happened while they were working and they had to fix it.
The tunnel rats are part of the Tunnel Task Force, which also includes representatives from Homeland Security, the Drug Enforcement Agency (DEA) and Immigration and Customs Enforcement (ICE). It was formed in 2003 as officials noticed that even though most drugs are driven across the border at ports of entry, hidden inside cargo trucks and other vehicles, tunnels were becoming a major issue.
Originally, the underground team was focused on smugglers who used existing storm drains and sewer systems to move people across the border illegally. As more and more cross-border tunnels were discovered — 13 in the San Diego sector alone in 2006 — the team began focusing on that. They developed skills in geology, air monitoring and emergency extractions.
After a tunnel is found and cleared of smugglers, the tunnel rats are called in to check it for evidence and map it. They make sure the air is safe and the ground stable, and then crawl in with tape measures, compasses and lasers. Then concrete is poured into the tunnels at various places on the U.S. side….
Team members said what they like most about the work is the variety.
Their work ebbs and flows from year to year. Through the end of August, seven tunnels — three operational and four not yet finished — had been discovered in the fiscal year that started Oct. 1, 2016, according to the Border Patrol. In the eights weeks so far this year: zero.
Sometimes the work has a feeling of deja vu. Officials on the Mexican side of the border don’t always have the resources to seal tunnels.
At least eight times in recent years, the Border Patrol says, newly discovered tunnels turned out to be old ones. The smugglers started in Mexico using what was already there and when they came to the concrete on the U.S. side, they dug around it — until they were found again, another round of hide-and-seek that shows no signs of ending.
