Former US Marine Angel Dominguez Ramirez Jr. was sentenced to over 16 years in federal prison after being found guilty of trafficking millions’ worth of cocaine from South America through the Mexican border. Ramirez Jr. holds both US and Mexican citizenship.

Ramirez Jr., originally from Guadalajara (some say Tamaulipas), Mexico, was sentenced Tuesday in San Diego, having previously pleaded guilty to International Conspiracy to Distribute Cocaine and Money Laundering Conspiracy.

The prosecution revealed that Ramirez Jr. headed an organization called El Seguimiento 39 or El Seg 39 (also known as “The Company”). According to court documents, the ex-Marine built El Seg 39 by utilizing alliances with the Cartel de Jalisco Nueva Generacion (CJNG), Beltran Leyva Organization (BLO), the Cartel del Golfo (CDG), the Sinaloa Cartel, and Los Zetas, all notorious drug organizations.

Other filed documents also revealed that Ramirez Jr. was in contact with corrupt high-level politicians in Mexico to cull investigations on his organization’s activities. One such Mexican official was Ivan Reyes Arzate, a top federal police commander who worked with US law enforcement.
