US drone, phone taps used to hunt Mexican drug lord
MEXICO CITY (AFP) - US authorities announced plans to seek the extradition of Mexico's most powerful drug lord after his capture in a US-backed operation that included a drone, cellphone intercepts and elite Mexican marines.
As prosecutors in New York prepared their request, new details emerged Sunday from the manhunt that led to the capture of Sinaloa cartel boss Joaquin "El Chapo" Guzman, whose empire has smuggled drugs to the US, Europe and Asia.
The US surveillance drone was used for two weeks between mid-January and mid-February to back up a massive operation 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, after escaping through tunnels under one of his safe houses as the marines closed in on him, Mexican and US officials said.
