The wife of 44-year-old Maksym Chernyak, who spoke to NBC6 on condition of anonymity, claims her husband did not suffer from any pre-existing medical condition. She alleges that he was not properly cared for at the Krome Detention Center when he started to feel sick.

Chernyak died on Feb. 20 at HCA Kendall Hospital in Miami while in ICE custody, according to the agency's website, which also notes that he was vomiting and having seizures. A doctor determined that the preliminary cause of death was a cerebral hemorrhage.
