A routine noise dispute at an Oklahoma City apartment complex turned deadly on August 27, 2016. Greg Papa Hill, 52, a Black maintenance worker at Liberty Station Apartments, heard an argument and a gunshot and went to intervene. Witnesses said additional shots rang out after he confronted those involved; Hill returned to an apartment saying he had been shot, then collapsed and later died.

Police identified 21-year-old Jimmy Simms as a suspect after Simms’ pregnant girlfriend told investigators she had driven to the complex to pick up another woman and saw Simms arguing. She said Simms got into her vehicle, brandished a handgun and fired into the dashboard before Hill approached and was shot. Simms was arrested and charged with first-degree murder and three counts of assault with a dangerous weapon.

Did anyone at Liberty Station Apartments know Greg Hill well or see what happened that morning?
