The man who fatally shot Ahmaud Arbery had previously used racial slurs in a text message and on social media, a prosecutor said Thursday as a judge weighed whether to grant bond for the defendant and his father. Travis McMichael and his father, Gregory McMichael, have been jailed since their arrests in May, more than two months after Arbery was slain. The McMichaels, who are white, chased and fatally shot the 25-year-old Black man after they spotted him running in their neighborhood just outside the port city of Brunswick.
