Black's heart condition and mental illness were significant factors in his "sudden cardiac death" during a struggle with law enforcement officers on Maryland's Eastern Shore, according to an autopsy report. The report, signed Wednesday, Jan. 23, 2019, by the state's chief medical examiner, didn't satisfy concerns by Anton Black's family that police used excessive force on the 19-year-old before his Sept. 15 death in Caroline County.
