The U.S. Treasury Department on Monday sanctioned a network of companies and their affiliates that allegedly supplied precursor chemicals to make fentanyl to a faction of Mexico's Sinaloa cartel.
A dozen Mexico-based companies and eight of the people managing them were accused of using their pharmaceutical, laboratory, chemical, cleaning and real estate businesses to purchase the chemicals and provide them to the Sinaloa cartel's “Chapitos” faction, run by sons of the former Sinaloa leader Joaquín “El Chapo” Guzmán.
