Tuan Van Bui, a 55-year-old Philadelphia man who arrived in the U.S. in 1990 through the Amerasian Homecoming Act, suffered a stroke and collapsed on April 1 at Miami Correctional Facility in Indiana, after being detained during a routine ICE check-in in Philadelphia the previous August and spending months at the Moshannon Valley Processing Center. Fellow detainees said it took about 15 minutes for a guard to respond and 10 more minutes for medical staff to arrive, while an Iraqi detainee performed CPR; ICE said Bui had a history of asthma and hypertension and received appropriate medication, and the local coroner attributed his death to natural causes related to cardiovascular disease, though the exact cause remains under investigation. His family is asking that his body be returned to Philadelphia for burial and is calling for an independent investigation, noting that his wife suffered a stroke after he was detained. His death is among 50 in ICE detention since Trump took office in January 2025, a rate more than double the 2009-2024 average.
