Biography

Mario Joseph died on March 31, 2025 in San Juan, Puerto Rico.

He led the prosecution of the Raboteau massacre in 2000, a landmark trial in a country where high-profile politicians and officials are rarely charged, let alone prosecuted.

Joseph's law firm also was involved in a claim on behalf of 5,000 cholera victims who blamed the U.N. for introducing the disease that killed nearly 10,000 Haitians.

He represented women who had children fathered by U.N. peacekeepers and sought child support against the absentee fathers and the U.N.

Joseph also co-managed the Bureau of International Attorneys in Port-au-Prince, Haiti's capital, which represented victims of human rights violations.
