Marquis Darrnell Green, 41, was killed in the early hours of June 29, 2025, in the breezeway of an East Side apartment complex in the 1500 block of Upland Drive in San Antonio. A dispute over suspected stolen property began at an apartment doorway and spilled into the corridor, where a struggle over a handgun ended with Green mortally wounded by a single gunshot to the chest; he was pronounced dead at the scene before dawn.

Detectives identified 34-year-old Gregory Bernard Cunningham Jr. as the man who confronted Green. A witness who said she was the victim’s significant other told investigators Cunningham, described as a relative of hers, believed Green had taken his belongings. Surveillance video allegedly shows the men struggling for control of the gun before Cunningham fired. Cunningham was arrested the next day, charged with murder, and held in the Bexar County jail on $250,000 bond awaiting indictment.

The case hinges on the witness account, the affidavit and court records, and the surveillance footage. Did anyone in the area see the argument or have additional video of the breezeway that morning?
