It described Wilson's face injuries after the shooting as photographed by a local detective at the Fraternal Order of Police building, instead of at Ferguson Police headquarters. An investigator with the County Medical Examiner's office testified he decided not to take measurements at the crime scene nor did he photograph the scene, instead relying on photographs taken by the County Police Department.
