Drug lord Rafael Caro Quintero has long been wanted by the DEA for killing of agent Enrique “Kiki” Camarena in 1985.

Mexico will extradite to the United States drug lord Rafael Caro Quintero, convicted of murdering a U.S. anti-narcotics agent in 1985, and more than two dozen other suspected cartel members, sources told Reuters on Thursday.

Mexico has extradited 29 alleged criminals to the United States, among them the so-called “narco of narcos” Rafael Caro Quintero, many accused of murder and several alleged members of cartels now designated as Foreign Terrorist Organizations.

Mexico has sent Quintero and 28 other cartel figures to the U.S. as the Trump Administration turns up the pressure on drug trafficking organizations.

Cartel leaders Rafael Caro Quintero and Vicente Carrillo Fuentes are set to be arraigned in a U.S. federal court in New York City on Friday, following their surprise transfer from Mexico. The pair were among 29 Mexican prisoners sent Thursday to eight cities across the U.

"Caro Quintero, a cartel kingpin who unleashed violence, destruction, and death across the United States and Mexico, has spent four decades atop DEA's most wanted fugitives list, and today we can proudly say he has arrived in the United States where justice will be served," DEA Acting Administrator Derek S. Maltz said in a press release.

The Mexican drug kingpin who was brought to the United States on Thursday is accused in the 1985 kidnapping, torture and murder of DEA agent Enrique “Kiki” Camarena.

Rafael Caro Quintero, nicknamed “El Narco de Narcos” (The Narco of Narcos) is the founder of the now defunct Guadalajara Cartel—one of the most powerful drug cartels of the 1980s that later splintered into various groups, including the Sinaloa Cartel, one of the world’s most powerful criminal organizations and drug cartels.
