In what amounts to a final chapter in the history of the once-mighty Norte del Valle Cartel, Colombia has extradited one of the organization’s former leaders to the United States.

According to authorities, Ramon Quintero Sanclemente, alias “RQ,” is believed to have been one of the main leaders of the cartel, which was based in the north of the Valle del Cauca department. Quintero was arrested on April 15, and is wanted in the United States on drug trafficking and money laundering charges.

Prior to his capture, he was allegedly allied with Javier Antonio and Luis Enrique Calle Serna, otherwise known as the “Comba” brothers, who lead the Rastrojos crime syndicate.
