Isaac Johnson, a 30-year-old African American man, was fatally shot in St. Louis on August 17, 2015. He was found after reports of gunfire with critical wounds that proved fatal. The shooting came during an overnight span of violence that same night in which two other people were injured; reports did not make clear whether those shootings were directly connected to Johnson’s death.

The St. Louis Metropolitan Police Department opened a homicide investigation, canvassing the area for witnesses and evidence and treating the case as a high-priority murder probe. Family and friends later held vigils and posted online memorials honoring him.

Did anyone in the area that night see or hear anything that could help identify who shot Isaac Johnson?
