As the trial of Joaquin "El Chapo" Guzman proceeds under heavy security, a witness took the stand to tell jurors more about the Mexican drug lord.
The witness Jesus Zambada is the brother of "El Mayo" Zambada who was the accused partner in running the Sinaloa Cartel. He gave a dramatic testimony as he described "El Chapo" as a ruthless killer who ordered the murder of a man only because he refused to shake his hand.
Guzman, 61, is on trial in Brooklyn federal court, charged with 17 criminal counts, and was until 2016 one of the most wanted fugitives.
Zambada also talked about another murder Guzman ordered, the murder of a corrupt official identified as Rafita. He also told the court about Guzman's investment in a 20-ton cocaine shipements intercepted by the U.S. Coast Guard leaving Panama.
