St. Louis County Medical Examiner (“SCLME”) to respond to the scene. To further protect the integrity of the crime scene, and in accordance with common police practice, SLCPD personnel did not permit family members and concerned neighbors into the crime scene (with one brief exception). Also in accordance with common police practice, crime scene detectives processed the crime scene with Brown’s body present. According to SLCPD CAP detectives, they have one opportunity to thoroughly investigate a crime scene before it is forever changed upon the removal of the decedent’s body. Processing a homicide scene with the decedent’s body present allows detectives, for example, to accurately measure distances, precisely document body position, and note injury and other markings relative to other aspects of the crime scene that photographs may not capture. In this case, crime scene detectives had to stop processing the scene as a result of two more reports of what sounded like automatic weapons gunfire in the area at 1:55 p.m. and 2:11 p.m., as well as some individuals in the crowd encroaching on the crime scene and chanting, “Kill the Police,” as documented by cell phone video. At each of those times, having exhausted their existing resources, SLCPD personnel called emergency codes for additional patrol officers from throughout St. Louis County in increments of twenty­five. Livery drivers sent to transport Brown’s body upon completion of processing arrived at 2:20 p.m. Their customary practice is to wait on scene until the body is ready for transport. However, an SLCPD sergeant briefly stopped them from getting out of their vehicle until the gunfire abated and it was safe for them to do so. The SLCME medicolegal investigator arrived at 2:30 p.m. and began conducting his investigation when it was reasonably safe to do so. Detectives were at the crime scene for approximately five and a half hours, and throughout that time, SLCPD personnel continued to seek additional assistance, calling in the Highway Safety Unit at 2:38 p.m. and the Tactical Operations Unit at 2:44 p.m. Witnesses and detectives described the scene as volatile, causing concern for both their personal safety and the integrity of the crime scene. Crime scene detectives and the SLCME medicolegal investigator completed the processing of Brown’s body at approximately 4:00 p.m, at which time Brown’s body was transported to the Office of the SLCME. C. Legal Summary 1. The Law Governing Uses of Deadly Force by a Law Enforcement Officer The federal criminal statute that enforces Constitutional limits on uses of force by law enforcement officers is 18 U.S.C. § 242, which provides in relevant part, as follows: Whoever, under color of any law, . . . willfully subjects any person . . . to the deprivation of any rights, privileges, or immunities secured or protected by the Constitution or laws of the United States [shall be guilty of a crime]. To prove a violation of Section 242, the government must prove the following elements beyond a reasonable doubt: (1) that the defendant was acting under color of law, (2) that he deprived a victim of a right protected by the Constitution or laws of the United States, (3) that he acted willfully, and (4) that the deprivation resulted in bodily injury and/or death.
