US drone, phone taps used to hunt Mexican drug lord

US authorities announced they will seek the extradition of Mexico's most powerful drug lord as new details of his American-backed capture emerged, including the use of a drone and cellphone intercepts. The US drone was used for two weeks between mid-January and mid-February during a massive hunt for Sinaloa cartel boss Joaquin "El Chapo" Guzman in the northwestern city of Culiacan, a US government official told AFP on condition of anonymity. Guzman eventually slipped out of Culiacan, the capital of Sinaloa state, escaping through tunnels under one of his safe houses as Mexican marines closed in on him, Mexican and US officials said. Under pressure, the 56-year-old drug capo, who had been on the run since escaping from prison 13 years ago, fled further south to the beach resort city of Mazatlan. It was there that the elite marine unit captured him on Saturday, in the fourth floor of a condominium, with a surprisingly small entourage that included one lookout, one bodyguard and a woman believed to be his beauty-queen wife, the US official said. "Cellular telephone intercepts were involved in the arrest," the official said, stressing that no drone was used in Mazatlan. The official said the remote-controlled aircraft was used in Culiacan to corroborate other intelligence and that Mexico's military had authorized its use. Despite being Mexico's most wanted man, Guzman had been spending most of his time in Culiacan, living in a network of safe houses with escape tunnels, extra thick walls and steel-reinforced doors, officials said. "It's a big city where he has his contacts, his women, his houses," the US official said. Officials had hoped that Guzman would flee to a rural, more open space to capture him, and his decision to run to Mazatlan around three days before his arrest was a surprise, the official said. His arrest capped a months-long operation that resulted in the arrests of a dozen Sinaloa cartel operatives, including alleged bodyguards of Guzman's top associate, Ismael "El Mayo" Zambada. A Mexican official said authorities are still searching for Zambada, who is seen as Guzman's natural successor. - US seeks extradition - Nabbing Guzman, who is considered the world's biggest drug trafficker, was a major victory in President Enrique Pena Nieto's push to rein in drug violence in his country. The Sinaloa cartel's turf wars with rival gangs contributed to a wave of drug violence that left more than 77,000 people dead in the past seven years. The United States had offered a $5 million reward for information leading to his capture, with several indictments in multiple cities from New York to San Diego. Robert Nardoza, a spokesman for the US Attorney's Office for the Eastern District of New York, said prosecutors there "plan to seek his extradition." A senior Republican lawmaker backed extraditing Guzman to the US, warning "the biggest fish ever" may try to slip the net again in a repeat of his 2001 escape. "I think that would be the best course for not only Mexico, but also the United States, in ensuring that what happened in 2001 does not happen again," Michael McCaul, chairman of the House Homeland Security Committee, told ABC television. A Mexican foreign ministry spokesman declined to comment on the planned extradition request. An official in the Mexican attorney general's office said Guzman has to finish the 20-year sentence he avoided by fleeing eight years into his prison term. But he is also facing new charges of drug trafficking, using illegal funds, organized crime and possession of weapons reserved for the military, the official said. The captured kingpin is not facing murder charges, the official said.
