A Michigan police officer who killed Patrick Lyoya after a traffic stop pressed the gun against the Black man’s head when firing the fatal shot. That's the opinion of an expert who performed an independent autopsy on Patrick Lyoya. The results were announced Tuesday. Dr. Werner Spitz says he confirmed what was seen last week on video: Lyoya was shot in the back of the head in Grand Rapids, Michigan, on April 4. Attorney Ben Crump says the white officer failed to ease up after a foot chase and physical struggle following a traffic stop. Results of the official autopsy haven’t been publicly released. State police are investigating the shooting.
