Adrian Dennard Gainer Jr. was a 16-year-old Black teenager from Jacksonville, Florida, remembered by family for his vibrant personality and as an aspiring rapper known to some as Bibby. On the afternoon of February 25, 2019, he was sitting with another man in a gazebo at the Hilltop Village Apartments on West 45th Street when a car pulled into the complex and two armed men carrying semi-automatic rifles emerged and immediately opened fire. Witnesses saw Gainer fall as he was shot while trying to flee; an arrest warrant says one of the shooters then ran up and shot him at close range in the back of his head or neck.

Investigators recovered 45 shell casings at the scene and linked one gunman through surveillance and witness testimony to Hakeem Robinson, known as Ksoo. Robinson was arrested and charged with second-degree murder; another man identified as Whitaker was also arrested in connection with the shooting. Gainer’s mother, Elizabeth Gainer, and his grandmother, Blanche Jordan, have since been public advocates against gun violence, holding marches and prayers in his memory.

Does anyone who lived near Hilltop Village Apartments in 2019 have information that could help complete the timeline or identify others who were there that day?
