A prosecutor says there's overwhelming proof that Mexican drug lord Joaquin "El Chapo" Guzman flooded the United States with ton-after-ton of cocaine.
Assistant U.S. Attorney Andrea Goldbarg told a jury in closing arguments Wednesday that the testimony by 14 co-operators, wiretaps and other evidence showed Guzman used corruption and violence to control his drug-trafficking empire.
The prosecutor began her argument by detailing testimony about how the Sinaloa cartel boss once cursed at two kidnap victims before shooting them in the head.
Guzman is facing multiple drug and murder conspiracy charges that could land him in prison for life if he's convicted.
The defence insists the allegations are fabricated.
The government's closing argument was expected to last most of Wednesday.
The defence's closing is set for Thursday.
