Former Haitian President Michel Martelly has made a rare return to Haiti (a Caribbean nation that has endured chronic political instability and gang violence) and is expected to testify in the ongoing judicial investigation into the 2021 assassination of President Jovenel Moïse. Martelly, who hand-picked Moïse as his successor within the same political party, has not been charged in the case and has lived in the United States since leaving office in 2016. His visit comes amid a backdrop of serious international sanctions — from the US, Canada, and the EU — over allegations that he facilitated drug trafficking and financed armed gangs, accusations he has not publicly addressed.
