Octavius Hamilton was 35 when he was killed in Detroit on October 11, 2021. Just after midnight he was walking near Beland and Lappin streets on the city’s east side when an unknown person began to pursue him. Ring doorbell footage shows the attacker chasing Hamilton, shooting him twice, and continuing to fire after he fell to the ground.

Police say the footage exists but is of poor quality, and detectives have not publicly identified a suspect. His mother, Cantrail Holmes, described her grief and said her son did not deserve such a fate. The Detroit Police Department opened an investigation and has asked the public for tips; no arrests have been announced.

If anyone has information about Hamilton’s movements that night or recognizes the person in the video, please contact Detroit police with what you know.
