Author: Sandra Dibble DRUG TUNNEL FROM TIJUANA SHUT DOWN Cross-Border Operation Nets 12 Tons of Marijuana, 22 Suspects The latest drug tunnel discovered between Tijuana and San Diego featured ventilation, lighting and a rail system capable of moving loads of wrapped marijuana across the border. Within hours of launching operations on Wednesday, the passageway was shut down, 22 suspects were under arrest and 12 tons of marijuana had been seized by U.S. and Mexican authorities. "We believe with a pretty good degree of certainty that the marijuana loads that began moving yesterday morning were the first drugs that moved through this tunnel," U.S. Attorney Laura Duffy said Thursday. The tunnel, about a half-mile in length, was one of the largest found in the area in recent years. It was described by U.S. officials as one of 10 sophisticated passageways uncovered in the area since 2006 capable of moving large amounts of narcotics from Mexico to the United States. Several major drug tunnels on the California border in recent years have been attributed to the Sinaloa Cartel, whose leader Joaquin "El Chapo" Guzman escaped from a maximum-security prison outside Mexico City in July through an elaborate tunnel. But detainees at the drug tunnel entrance in Tijuana told authorities there that they had been working for a criminal group operating in the state of Jalisco. David Shaw, special agent in charge of Homeland Security Investigations (HSI) in San Diego, said Thursday that the investigation was continuing and that "we're not ready to make a public statement on that yet." U.S. authorities said the tunnel's discovery on Wednesday came after an investigation launched last May in San Diego by HSI involving two undercover agents. According to court documents, an undercover HSI agent made contact with one of the suspects, a 53-year-old Mexican citizen named Isaias Enriquez Acosta. The undercover agent was told that drivers would receive $10,000 per load to move "stuff," which he understood to be drugs, from a warehouse near the U.S. border. The warehouse turned out to be the tunnel's U.S. exit in a building on Otay Center Drive near Customhouse Plaza, just west of the Otay Mesa Port of Entry. The undercover HSI agent and a companion picked up their first load about 7:15 a.m. Wednesday and drove it to the second warehouse at an undisclosed location. There, they unloaded about 249 bundles of a "green leafy substance containing the strong odor of marijuana and wrapped in clear plastic," according to the court documents. At 11:15 a.m., the HSI agent met with Enriquez and a second suspect, a 27-year-old Mexican citizen named Isidro Silva Acosta, at a San Diego restaurant. There, they made arrangements to move a second load. But at 5:30 p.m., 30 agents with HSI's Special Response Team moved in on the Otay Center Drive warehouse, arresting Silva, according to a news release from the U.S. Attorney's Office. Enriquez was arrested at a nearby hotel, it said. Inside the warehouse, agents found a hole about 3 feet in diameter that dropped down about 32 feet and led to an underground tunnel. Peering inside the passageway, agents saw additional plastic-wrapped bundles. By Thursday, the U.S. agents had seized close to 2 tons of marijuana from the warehouse and the tunnel. Silva and Enriquez were arraigned Thursday in federal court. They were charged with unlawful conspiracy to import a controlled substance and conspiracy to use border tunnels and passages. Duffy said four additional suspects were arrested by the San Diego County Sheriff's Department, "in connection with the movement of the marijuana from the undercover warehouse" to various San Diego residences and businesses. Duffy said they would be charged by the San Diego District Attorney's Office. The District Attorney's Office and the Sheriff's Department declined to reveal the suspects' names on Thursday. In Mexico, federal police announced the arrests of 16 suspects at a warehouse that covered the tunnel's Tijuana entrance south of the border fence. A statement said that "an intense movement of trucks and vans came and went," from that location, "apparently to drop off drugs for their transfer to the United States." The suspects, ranging in age from 21 to 50, told federal prosecutors that their task was to wrap the marijuana and send it, the statement said. All but one of the detainees said they were from the state of Sinaloa. The passageway dropped about 30 feet from the warehouse, according to Mexican authorities. The tunnel was shored up with metal tubes to avoid its collapse, they said. It included lights and ventilation, and a rail system to move the drugs. According to preliminary calculations, the tunnel measured about 2,600 feet, with three-fourths of its extension in Mexican territory. Authorities seized 873 packages weighing about 10 tons that were headed to the U.S., the statement said. U.S. authorities have detected more than 80 cross-border smuggling tunnels in the last five years, with most of them in California and Arizona. The clay soil of the Otay Mesa area offers stability for cross-border tunnels that would be more likely to crumble in sandy soils found elsewhere, U.S. authorities say. The area also has warehouses on both sides of the border, making it easy to blend in, Duffy said, and quick routes to interstate - --- MAP posted-by: Jay Bergstrom
