to the right side of his face and on the back of his left hand. The autopsy noted the absence of stippling, powder burns around a wound that indicate a shot was fired at a relatively short range. Michael Graham notes gunshot wounds within an inch of the body do not always cause stippling. Microscopic examination of tissue taken from Brown's thumb wound detected the presence of a foreign material consistent with the material which is ejected from a gun while firing. The gunshot wound to the top of Brown's head was consistent with Brown either falling forward or being in a lunging position; the shot was instantly fatal. A toxicology test performed by a University laboratory revealed the presence of THC, the active ingredient in marijuana, in Brown's blood and urine. This indicated he used marijuana within a few hours of his death, but not whether he was impaired when he died. Independent At the request of Brown's family, on a preliminary autopsy was conducted by Michael Baden, a former chief medical examiner for the City of New York (1978–1979). This autopsy was limited because the previous county autopsy had washed, embalmed, and taken evidence off the body. According to Baden's report, Brown was shot six times into his front: four of the bullets entered his right arm, one entered his right eye on a downward trajectory, and one entered the top of his skull. All of the rounds were fired from a distance of at least one foot. One of the shots shattered Brown's right eye, traveled through his face, then exited his jaw and reentered his collarbone. Brown could have survived the first bullet wounds, but the bullet that entered the top of his head resulted in a fatal injury. Baden had no access to the clothing of the victim, and had not yet seen the x-rays showing where bullets were in the body. He could not determine if any gunpowder residue was on that clothing. Baden concluded there was too little information to forensically reconstruct the shooting. At least two commentators noted the results of both autopsies contradicted some aspects of some eyewitness accounts, which had reported Wilson shot Brown in the back and that Wilson shot Brown while holding Brown's neck. In later analysis, Baden reclassified one of Brown's chest wounds as an entry wound. Baden was assisted by Shawn Parcells, who did not have
