A mass shooting at a downtown St. Louis office building on June 18, 2023, left 17-year-old Makao Moore dead. The party on the fifth floor of a Washington Avenue building, promoted on social media and attended largely by teenagers and young adults, erupted into gunfire shortly after 1 a.m. Police found liquor bottles and numerous shell casings from handguns and AR-style rifles; ten teenagers, ages 15 to 19, were shot and another teenage girl was injured after being trampled while fleeing.

Makao Moore was pronounced dead at the scene. Police initially took a 17-year-old male into custody and later released him as the investigation continued. In August 2023 a 16-year-old male was arrested on an assault charge accused of shooting one of the surviving victims. Authorities say they are still searching for several other individuals believed to be involved.

Does anyone who attended or lived near Washington Avenue that night have photos, video, or information that could help investigators?
