The autopsy did not reveal signs of a struggle, Dr. Baden said, which casts doubt on an earlier statement by police that a struggle between Brown and Wilson precipitated Brown’s shooting. Police have said Brown forced his way inside Wilson’s cruiser, where Wilson shot at Brown for the first time.
Dr. Baden said he found no gunpowder residue on Brown’s skin, which could mean that the muzzle of Wilson’s gun was “at least one or two feet away” from Brown when he was shot. However, Dr. Baden was adamant that he would need to examine Brown’s clothing for gunpowder residue to make a conclusive finding.
Brown’s clothing was not available for Dr. Baden and Prof. Parcells to examine, Baden said, though it was almost certainly examined during Brown’s first autopsy performed by the St. Louis County Medical Examiner.
If no gunpowder residue was found on Brown’s clothing during the first autopsy, it will likely throw the Ferguson PD’s timeline of events into question.
Prof. Parcells said a wound on Brown’s right arm was “consistent with a witness statement” that Brown was first shot while facing away from Wilson, but he stressed that he and Dr. Baden could not determine conclusively the trajectories of the bullets that hit Brown—or which direction he was moving—when he was shot. The wounds “could be consistent with going forward or going backward,” Dr. Baden said.
