Investigation and Analysis of Organized Crime

This investigative series looks at the role that Mexico and its cartels have played in making the lethal opioid fentanyl a growing threat in the United States. While China accounts for the overwhelming majority of fentanyl production, Mexican gangs have also become key links in this chain, transporting, selling, and even producing the drug. Here we examine the rise of fentanyl, from production facilities in China and Mexico, to the potential role of the Sinaloa Cartel and numerous subcontractors.
