The SLCPD Crime Laboratory conducted DNA analysis on swabs taken from Wilson, Brown, Wilson’s gun, and the crime scene. Brown’s DNA was found at four significant locations: on Wilson’s gun; on the roadway further away from where he died; on the SUV driver’s door and inside the driver’s cabin area of the SUV; and on Wilson’s clothes. A DNA mixture from which Wilson’s DNA could not be excluded was found on Brown’s left palm. Analysis of DNA on Wilson’s gun revealed a major mixture profile that is 2.1 octillion times more likely a mixture of DNA from Wilson and DNA from Brown than from Wilson and 19 anyone else. This is conclusive evidence that Brown’s DNA was on Wilson’s gun. Brown is the source of the DNA found in two bloodstains on Canfield Drive, approximately 17 and 22 feet east of where Brown fell to his death, proving that Brown moved forward toward Wilson prior to the fatal shot to his head. Brown’s DNA was found both on the inside and outside of the driver’s side of the SUV. Brown is the source of DNA in blood found on the exterior of the passenger door of the driver’s side of the SUV. Likewise, a piece of Brown’s skin was recovered from the exterior of the driver’s door of the SUV, consistent with Brown sustaining injury while at that door. Brown is also the source of the major contributor of a DNA mixture found on the interior driver’s door handle of the SUV. A DNA mixture obtained from the top of the exterior of the driver’s door revealed a major mixture profile that is 6.9 million times more likely a mixture of DNA from Wilson and DNA from Brown than from Wilson and anyone else. Brown’s DNA was found on Wilson’s uniform shirt collar and pants. With respect to the left side of Wilson’s shirt and collar, it is 2.1 trillion times more likely that the recovered DNA mixture is DNA from Wilson and DNA from Brown than from Wilson and anyone else. Similarly, with respect to a DNA mixture obtained from the left side of Wilson’s pants, it is 34 sextillion times more likely that the mixture is DNA from Wilson and DNA from Brown than from Wilson and anyone else. Brown is also the source of the major male profile found in a DNA mixture found in a bloodstain on the upper left thigh of Wilson’s pants. DNA analysis of Brown’s left palm revealed a DNA mixture with Brown as the major contributor, and Wilson being 98 times more likely the minor contributor than anyone else. DNA analysis of Brown’s clothes, right hand, fingernails, and clothes excluded Wilson as a possible contributor. 4. Dispatch Recordings 19 While it is possible that Wilson inadvertently transferred Brown’s blood from his own hand to his gun either after the struggle or while packaging his gun (even though Wilson claimed to have already washed his hands), such a possibility is speculative. The autopsy results and bullet trajectory are consistent with Brown’s DNA being present on the gun as a result of the struggle over the gun. Regardless, the absence of Brown’s DNA on Wilson’s gun would not change the prosecutive decision. 21
