SAVANNAH, Ga. The Georgia man whose cellphone video of Ahmaud Arberys fatal shooting helped reignite the case was charged with murder Thursday, making him the third person arrested more than two months after the slaying. Arbery was slain Feb. 23 when a white father and son armed themselves and pursued him after spotting the 25-year-old black man running in their neighborhood. Gregory McMichael told police he suspected Arbery was a burglar and that Arbery attacked his son before being shot. The video shows Arbery run around the truck to the right before he cuts back in front of it. Arbery can be seen punching a man holding what appears to be a shotgun, who then fires a third shot point-blank.
