Aaron Salter was a beloved community member and security guard who knew the shoppers of Tops Friendly Market by name. When they came under attack from a gunman with a rifle, he sprang into action. The retired Buffalo police officer fired multiple times at the attacker, striking his armor-plated vest at least once. The bullet didn't pierce, and Salter, 55, was shot and killed. “He’s a true hero," Buffalo Police Commissioner Joseph Gramaglia said Sunday. “There could have been more victims if not for his actions.” Salter was one of 10 killed in an attack whose victims represented a cross-section of life in the predominantly Black neighborhood in Buffalo, NY. They were gunned down by a white man who authorities say showed up at the store with the “express purpose” of killing Black people, one of whom was Salter. Three others were wounded.
