Justo Betancourt, a 54-year-old Cuban national who entered the U.S. in 1990 and held lawful status, was detained by ICE on October 29, 2025, during a routine annual immigration check-in. He was held for roughly seven months at the South Florida Detention Facility, known as Alligator Alcatraz, despite being unable to be readily deported to Cuba. During detention he was shackled up to 23 hours a day and denied adequate care for his diabetes, neuropathy, and heart conditions, leading to strokes, cardiac arrest, a diabetic coma from withheld insulin, significant weight loss, and lasting neurological damage including tremors and mobility impairment. His daughter Arianne organized weekly vigils outside the facility for 44 weeks advocating for his release. U.S. District Judge Kyle Dudek granted his habeas corpus petition on May 13, 2026, finding the detention erroneous and unlawful, and ordered his release within 48 hours; Betancourt was freed on May 14-15, 2026.
