A domestic dispute in the predawn hours at an apartment complex on Vanira Avenue in Peoplestown ended with the shooting death of 43-year-old Mario Peterson. Atlanta police responded to reports of a shooting at about 12:30 a.m. on June 24, 2021, and found Peterson deceased at the scene from a gunshot wound. Investigators said Peterson, a Black man, had been arguing with a woman he knew; the dispute culminated in the discharge of a firearm.

The woman, an acquaintance, was detained at the scene and cooperated with questioning, though early reports did not make clear who fired the weapon. A later update identified a suspect, Sequoyah Howard, 32, who was charged with murder in connection with Peterson’s death. Mario Antoine Peterson, born December 6, 1977, was a father of four from the Summerhill/Peoplestown area, remembered by his obituary for his big heart and love of his community.

Does anyone with information about that night or who knew Mario have details that could help the investigation?
