Wilson and other witnesses stated that Brown then reached into the SUV through the open drivers window and punched and grabbed Wilson. This is corroborated by bruising on Wilsons jaw and scratches on his neck, the presence of Browns DNA on Wilsons collar, shirt, and pants, and Wilsons DNA on Browns palm. While there are other individuals who stated that Wilson reached out of the SUV and grabbed Brown by the neck, prosecutors could not credit their accounts because they were inconsistent with physical and forensic evidence, as detailed throughout this report.
Brown then grabbed the weapon and struggled with Wilson to gain control of it. Wilson fired, striking Brown in the hand.
Autopsy results and bullet trajectory, skin from Browns palm on the outside of the SUV door as well as Browns DNA on the inside of the drivers door corroborate Wilsons account that during the struggle, Brown used his right hand to grab and attempt to control Wilsons gun. According to three autopsies, Brown sustained a close range gunshot wound to the fleshy portion of his right hand at the base of his right thumb. Soot from the muzzle of the gun found embedded in the tissue of this wound coupled with indicia of thermal change from the heat of the muzzle indicate that Browns hand was within inches of the muzzle of Wilsons gun when it was fired. T
he location of the recovered bullet in the side panel of the drivers door, just above Wilsons lap, also corroborates Wilsons account of the struggle over the gun and when the gun was fired, as do witness accounts that Wilson fired at least one shot from inside the SUV.
