CHARLOTTE, N.C. (AP) — A man charged in the fatal stabbing of a Ukrainian refugee on a North Carolina commuter train cannot currently stand trial because of his mental illness and will undergo medical treatment to try to restore his competency, a federal judge ruled Tuesday.Decarlos Brown Jr., 35, faces a federal charge of causing death on a mass transportation system in the killing of 23-year-old Iryna Zarutska in Charlotte, a charge that is punishable by death. A separate state case against Brown in which he is charged with first-degree murder is on pause pending the outcome of the federal case. At the request of Brown’s attorneys, U.S. District Judge Kenneth D. Bell found that their client is not currently competent to stand trial and ordered him to spend up to four months in a prison medical facility to try to restore his competency.

Defense attorneys said in a court filing Tuesday that Brown insisted that they provide the judge with the following information: “I would like to tell the court I have a body emergency. Someone has full access to my body and they are controlling me wrongfully. And law enforcement refuses to investigate it. And it requires for an investigation. When describing the technology someone was using I was misdiagnosed with schizophrenia.”
