NEW YORK—A key prosecution witness in the U.S. trial of Joaquin “El Chapo” Guzman on Nov. 15 told jurors that there were “a lot of deaths” as the accused Mexican drug lord and his associates built the Sinaloa Cartel in the 1990s through bloody conflict with rival drug traffickers.
Jesus Zambada told the jury that his brother, Ismael “El Mayo” Zambada, and Guzman used armies of sicarios, or assassins, to kill their enemies. Zambada, who has pleaded guilty to U.S. criminal charges, was testifying for a second day in Brooklyn federal court under an agreement to cooperate with prosecutors.
