Drug baron Joaquin “El Chapo” Guzman paid huge bribes to Mexican prosecutors, police, military and even Interpol to ensure smooth operations for his Sinaloa cartel, a key informant said at his US trial on Thursday. Jesus “El Rey” Zambada, brother of the cartel’s co-head, the still-at-large Ismael “El Mayo” Zambada, detailed the eye-watering costs of protecting cocaine shipments from Colombia to the US via Mexico. Zambada, who worked for the cartel from 1987 until his arrest in 2008, was returning to the witness box on the third day of a trial expected to last about four months. He told the court that as the head of the organisation’s operations in the capital city, he personally paid bribes to the attorney general’s office, the federal highway police that also operates bridges and airports, federal, state and local police forces, and “Interpol, as well”. “The bribes for officials in Mexico City were about US$300,000 per month,” the 57-year-old said, wearing a blue prison suit with an orange shirt. Zambada said he once paid a US$100,000 bribe to General Gilberto Toledano, in charge of the state of Guerrero, at Guzman’s request. “I was going to import cocaine from Colombia through the state of Guerrero … and El Chapo told me, ‘Go and meet General Toledano, he’s my friend, and give him US$100,000 from me,’” Zambada said. Drug lord ‘El Chapo’ is hallucinating and may be ‘going crazy’ in solitary confinement, lawyers say He also recounted violent turf wars, describing how his brother joined El Chapo and the Sinaloa cartel after working for another gang in the Tijuana border zone – triggering brutal infighting between the two clans. Among the killings he mentioned was an infamous 1992 gun battle in a seaside disco in the resort town Puerto Vallarta that left six dead but which failed to take out the head hitman of the rival gang, Ramon Arellano Felix. And in 1993, a cardinal, Juan Jesus Posadas, was murdered after he had the misfortune of going to the airport in the same brand of car as El Chapo – and was mistakenly targeted by the Tijuana group. According to Zambada, El Chapo finally murdered the leader of Tijuana’s hired gunmen in 2002, and he confided years later: “If there is one thing that makes me want to live, it is to have killed Ramon Arellano Felix.” Guzman, wearing a dark suit and tie, listened attentively to the testimony of his former ally. Brought to the US almost 22 months ago, Guzman, 61, is accused of smuggling more than 155 tons of cocaine into the United States over 25 years and faces life in prison if found guilty. His lawyers argue he has been scapegoated by Mexico’s “corrupt” government and the US Drug Enforcement Administration, and that the cartel’s true chief was Ismael Zambada.
