Calvin Maurice Hall, 36, was shot three times in the back at a block party in the Homewood neighborhood of Pittsburgh on July 14, 2019. An off‑duty Pittsburgh police officer who had served two years with the Pittsburgh Bureau of Police and previously worked with the Braddock Police Department and Point Park University Police, Hall had been visiting friends and family and is described as having tried to de‑escalate a dispute before walking away when he was struck.

Hall was taken to UPMC Presbyterian Hospital and died from his wounds on July 17, 2019. Investigators named Christian Bey as a person of interest; Bey was arrested on a parole violation shortly after the shooting and later charged with criminal homicide. Prosecutors reported DNA evidence on the murder weapon and the defense contested the investigation, saying it was rushed and that multiple people at the chaotic scene had firearms.

What additional details about the incident or those present that night can anyone in Homewood share to help clarify what happened?
