WASHINGTON (CNN) -- A Mexican cartel leader, best known as the brother of the man who killed DEA Agent Enrique "Kiki" Camarena, pleaded guilty in Denver, Colorado, to drug trafficking charges on Friday.
Nearly 20 years after his indictment, Miguel Angel Caro-Quintero, 46, admitted trafficking more than 100 tons of marijuana, and sending more than $100 million to Mexico. Caro-Quintero, who faces between 10 to 20 years, is scheduled for sentencing on February 4.
He faces up to five more years for drug charges in Arizona, stemming from a 1994 indictment.
Caro-Quintero was arrested in Sinaloa, Mexico, in 2001 and extradited to Colorado in February after spending eight years in custody for weapons crimes in Mexico.
