Joaquín “El Chapo” Guzmán’s greatest fear became true in January 2017, when he was extradited to the United States. For years, the kingpin had escaped US courts by staying in his native Mexico and staging two spectacular escapes from prison. However, and perhaps due to a Twitter war where he threatened incoming US president Donald Trump, the Mexican authorities expedited his extradition. He has been locked in a maximum security prison in New York since then.

His long-awaited trial started on November 5 and all signs point to a very long and very complicated judicial processes. Thousands of files and pieces of evidence will be presented by the defense and the prosecutors, and chances are the jury will feel overwhelmed by all the information. The trial will highlight the contradictory public persona that El Chapo has in Mexico and the US: some see him as a ruthless criminal while others, particularly in his native state of Sinaloa, see him as a righteous messiah who is providing for his people what the Mexican State hasn’t.

Here’s 21 facts about the trial and what has happened so far.
