A father and son are now facing murder charges after a shooting killed an unarmed black man back in February out on his daily run in Georgia. Ahmaud Arbery was running when the two armed white men chased him down and confronted him. The incident ended with one of them shooting Maud. NBC's Bill Zimpfer has some of the odd twists and turns of the case that could soon prompt an investigation by the U.S. Department of Justice.
