was slowed due to safety concerns regarding the sound of gunfire in the area and some hostile members of the crowd encroaching on the crime scene. An investigator from the St. Louis County Medical Examiner's office arrived at 2:30 p.m. Brown's body was removed at 4:00 p.m. Local residents criticized authorities for leaving Brown's body in the street for four hours in an action seen as demeaning and disrespectful.
