Tuan Van Bui, a 55-year-old Vietnamese national who legally entered the U.S. in 1990 under the Amerasian Homecoming Act, died on April 1, 2026, at Miami Correctional Facility in Bunker Hill, Indiana while in ICE custody. Staff found him unresponsive, initiated CPR, and called emergency services; he was pronounced dead at 6:10 p.m. His autopsy ruled the death natural, caused by hypertensive arteriosclerotic cardiovascular disease. Bui had been ordered removed from the country by an immigration judge in 2005 and was challenging his detention through a habeas corpus petition at the time of his death. His death was the second at the facility since October 2025, prompting the ACLU of Indiana to call for transparency and advocates to organize a statewide day of action on May 16, 2026, with over 70 protesters rallying at the Allen County Courthouse in Fort Wayne.
