‘Narco of narcos’: drug lord Rafael Caro Quintero arrested in Mexico

Co-founder of Guadalajara cartel was one of FBI's most-wanted fugitives after being freed from prison in 2013

Rafael Caro Quintero, a drug lord known as the narco of narcos" who was behind the killing of a US drug enforcement agent in 1985, has been captured by Mexican forces nearly a decade after walking out of prison, according to the country's navy.

Caro Quintero was arrested after a search dog named Max found him hiding in brush in the town of San Simon in Sinaloa state during a joint operation by the navy and the attorney general's office, a navy statement said. The site was in the mountains near Sinaloa's border with the northern border state of Chihuahua.
