U.S. District Judge Brian Cogan lauded the jury's meticulous attention to detail. Jurors finished a fifth day of deliberations without a verdict on Monday at the US trial of Guzman.
A grand jury in New York City found Mexican drug cartel kingpin Joaquin "El Chapo" Guzman guilty on all counts; setting the stage for a high-stakes sentencing hearing that could send the global criminal to prison for the rest of his life. He has pleaded not guilty and could be sentenced to life in prison if convicted.
Known as one of the most notorious and infamous drug traffickers in modern history, Guzman managed to evade authorities and broke out of Mexican prisons twice.
The verdict reached on the sixth day of jury deliberations could put the 61-year-old behind bars for the rest of his life in a high-security US prison selected to thwart another one of the escapes that embarrassed his native country. After he was recaptured in 2016, he was extradited to the United States to face American federal charges.
