NEW YORK—Prosecutors in the trial of “El Chapo” Joaquin Guzman on Jan. 8 played excerpts from what they said were incriminating phone calls made by the accused Mexican drug lord and intercepted by the FBI after they infiltrated his encrypted messaging system.
Nearly two months into the trial of Guzman on charges of drug trafficking as leader of the Sinaloa cartel, FBI special agent Steven Marston testified the 61-year-old was easily identifiable by his higher-pitched voice, which had “kind of a sing-songy nature to it” and a “nasally undertone.”
