The case that has caused outrage and grief across the nation: the family of Ahmaud Arbery, a 25-year-old Georgia man who was killed in February, say he was simply out for an afternoon jog when he was shot and killed after being confronted by two armed men in a pickup truck. The two men, charged with murder and aggravated assault almost three months after the incident, claim that they believed Arbery was a burglary suspect and they acted in self-defense. Arbery’s parents speak out.
