Courtney Jackson was a 36-year-old African American man from Chicago who was killed on April 17, 2015, after a sequence of violent events that day. Earlier that day Jackson had been in a fistfight with a friend of 20-year-old Jamal Joiner; that fight reportedly left Joiner’s friend with a lost tooth. Later that evening Jackson and a friend were driving when they encountered Joiner and a group. Joiner approached their vehicle and fired a handgun. Jackson was struck in the side and taken to Stroger Hospital, where he died; the bullet also passed through the driver’s neck, but the driver survived.

Jamal Joiner was arrested and charged with first-degree murder and attempted murder in connection with the shooting. Prosecutors said the shooting was retaliatory following the earlier altercation. Joiner had prior convictions listed, including robbery and possession of a controlled substance, and was held without bail as the case moved forward.
