On September 2, 2024, the organization "Ensemble contre la Corruption" (ECC) issued an open letter to Hans Ludwig Joseph, the Director General of the Anti-Corruption Unit (ULCC), requesting an investigation into the assets accumulated in Haiti by former President Michel Joseph Martelly, his family members, and close associates. This request is made in accordance with the Law of March 12, 2014, on the prevention and repression of corruption, and the Decree of April 30, 2023, which sanctions money laundering, the financing of terrorism, and the proliferation of weapons of mass destruction in Haiti.

In its letter, ECC highlighted various alleged offenses, including the U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) sanctions against former President Michel Joseph Martelly for drug trafficking, as well as accusations of systematic looting of public funds under his administration, particularly those from the PetroCaribe program. The organization emphasized that the current situation is ripe for such an investigation.
