Arbery, 25, was chased and gunned down by two white men, who said they believed he was a burglar, while jogging through Brunswick, Georgia, on Feb. 23. Police have identified the two men who chased him as Gregory McMichael, 64, and his son, Travis McMichael, 34. Neither has been arrested or charged, and the investigation is ongoing.
"I’m sorry Ahmaud (Rest In Paradise) and my prayers and blessings sent to the heavens above to your family," James wrote alongside a picture of Arbery. "#StayWoke. #ProfiledCauseWeAreSimplyBlack."
Arbery's family attorneys have also released a video that appears to show the fatal shooting of Arbery and are calling for authorities to arrest the McMichaels.
