Dameian L. Williams, a 48-year-old Black man from Jeannette, Pennsylvania, was shot and killed on September 6, 2019, outside McKee Stadium during the closing minutes of a high school football game between Jeannette High School and Imani Christian. Violence erupted near the main gate outside the stadium fence; police and emergency responders converged on the scene and the crowd was evacuated.

Authorities identified Greg A. Harper, then 40 and also of Jeannette, as the suspected shooter. Harper was taken into custody and initially charged with criminal homicide and reckless endangerment. Harper told court he fired after being attacked from behind and knocked down, claiming he acted in self-defense. Prosecutors proceeded to trial, but in 2022 Harper pleaded guilty to third-degree murder; other counts, including first-degree murder and reckless endangerment, were dismissed. The court sentenced him to 11 to 25 years in prison. Harper later sought to withdraw the plea and appealed, asserting he had been misled and coerced, but a judge found he had been properly informed.
