The U.S. Treasury Department has imposed sanctions on an individual accused of laundering money for the Sinaloa drug cartel through cryptocurrency channels. The Office of Foreign Assets Control (OFAC) identified the network as transferring proceeds from fentanyl, cocaine, and methamphetamine sales back to Mexico, utilizing U.S.-based cash couriers and digital currency addresses. Rodrigo Alarcon Palomares, a key figure in the network, was indicted by a federal grand jury in Colorado in April 2024 for allegedly laundering drug proceeds via cryptocurrency.
