Mexican drug lord pleads not guilty to killing of DEA agent after US extradition

Rafael Caro Quintero arraigned in New York over federal agent's death after years as one of US's most wanted men

After years as one of US authorities' most wanted men, the Mexican drug cartel boss Rafael Caro Quintero was brought into a New York courtroom on Friday to answer charges that include orchestrating the 1985 killing of a US federal agent.

Caro Quintero pleaded not guilty to running a continuing criminal enterprise. Separately, so did Vicente Carrillo Fuentes, the leader of another cartel. Carrillo is accused of arranging kidnappings and killings in Mexico but not accused of involvement in the death of the DEA agent Enrique Kiki" Camarena.
