On the evening of April 29, 2016, a volley of gunfire in the Walnut Park East neighborhood of St. Louis, Missouri, left multiple people wounded and two dead. One of the fatalities was 63-year-old Richard Graham, who was shot and later died at the scene or from his injuries; he was one of three people struck in that incident. Homicide detectives from the St. Louis Metropolitan Police Department opened an investigation immediately, treating the deaths as criminal homicides amid a wider outbreak of violence in the area that night.

Online memorials later noted Graham as a victim of gun violence. If anyone witnessed the shooting or has information that could help clarify what happened that night, please come forward and share what is known.
