Anthony Brown, 24, was shot and killed in Saint-Louis, Missouri, on May 14, 2017, during an altercation in a neighborhood with known crime problems. Witnesses reported hearing gunfire and seeing a person flee the scene. Police treated the death as a homicide and opened an immediate investigation.

Detectives canvassed the area, collected evidence, and interviewed witnesses. Investigators obtained surveillance footage from nearby cameras that, together with eyewitness accounts, pointed to a single suspect. An arrest followed and the suspect was charged with first-degree murder and armed criminal action. At trial, the prosecution relied on the surveillance footage and witness testimony while the defense argued self-defense, saying Brown had started the confrontation; the jury found the defendant guilty.

Anyone who knew Anthony Brown, saw activity in that neighborhood on May 14, 2017, or has information about the shooting is asked to come forward.
