On July 15, 2021, a summer evening gathering outside the Pick’n’Pay at Joseph E. Boone Boulevard and Chappell Road in Atlanta ended in gunfire from a passing dark-colored sedan. Three people were struck: 36-year-old Joshua Evans died at the scene; 42-year-old Chicorley Vickers was critically wounded and later died in August; a woman with the pair suffered a minor graze.

The Atlanta Police Department identified suspects in the shooting. Nineteen-year-old Antonio Waller was arrested and charged with murder. In October, 18-year-old Jontravious De’Anthony Arnold was taken into custody after being seen in a stolen vehicle and crashing during a police pursuit; he was charged with two counts of murder, aggravated assault, and possession of a firearm during the commission of a felony.
