D.E., a 44-year-old Mexican national, was detained by ICE without a warrant just two blocks from his home in Long Branch, NJ, interrupting chemotherapy scheduled to begin the same week for a brain tumor he has had for 12 years. He was initially held at Delaney Hall in Newark before being transferred to the California City Detention Center, where a CoreCivic guard was more than five hours late delivering his twice-daily seizure medication, Keppra, leading to a severe nighttime seizure. D.E. said he jammed his arm between his bed frame and the wall to keep himself from falling into the nearby toilet during the episode, and later filed a written medical grievance requesting a cancer specialist that went largely unaddressed. His case was cited in a broader review finding that the immigration detention grievance system, meant to allow detainees to report medical neglect and abuse, has collapsed amid the dismantling of federal oversight offices.
