Carlos Alberto Renteria Mantilla

Carlos Alberto "Beto" Rentería Mantilla (born March 11, 1945 in Tuluá, Valle del Cauca) is a former Colombian narcotrafficker and crime boss, presumed leader of the Norte del Valle Cartel. Rentería is believed by the United States government to be holding a leadership position within the drug cartel, he has been labeled "one of Colombia's most powerful and sophisticated narcotics traffickers" by Adam Szubin, Director of the Office of Foreign Assets Control, United States Department of the Treasury. The Attorney General of Colombia and the Colombian National Police accuse Rentería of narcotrafficking and money laundering.

As chief in the Norte del Valle Cartel, it is believed Rentería shares in the decision making of the cartel in aspects of transportation of drug shipments, bribery of political officials and assassinations. Rentería also operates his own organization under the Cartel capable of multi-ton cocaine shipments, as well as investing in other cocaine smuggling transports. The Norte del Valle cartel operates principally out of the North Valle del Cauca region. It is believed the cocaine is shipped from around the neighboring Colombian Departments as well as Peru and other South American countries before being transported again via trucks and airplanes to the Pacific Coast port of Buenaventura, Colombia. From Buenaventura the cocaine, through Renterías' operation, is primary transported to Mexico before being shipped again to the United States via go-fast boats, fishing vessels, and other maritime shipping methods.
