Decarlos Brown Jr. is a 34-year-old man who was arrested for the fatal stabbing of a 23-year-old Ukrainian woman named Iryna Zarutska on a light rail train in Charlotte, North Carolina. He was charged with committing an act causing death on a mass transportation system, a federal crime that could make him eligible for the death penalty. Brown has a lengthy criminal record, including felony convictions for armed robbery, breaking and entering, and larceny. He served a five-year prison term for robbery with a dangerous weapon and was released in 2020. Following his release, Brown displayed signs of severe mental illness, including a diagnosis of schizophrenia, and exhibited disturbing behavior. His family revealed he refused to take prescribed medication, and he was briefly hospitalized before being discharged to family care. Brown was arrested multiple times even after his release, including for misusing the 911 system, where he claimed he had a "chip" implanted in him. The case has drawn national attention, with prosecutors seeking the maximum penalty and political figures citing it in debates about crime and public safety policies.
