Antoine Randle, a 35-year-old African American man, was found with multiple gunshot wounds and died at the scene in a Chicago residential area on June 14, 2016. Reports say the attack appeared targeted and premeditated; investigators treated the death as a homicide and launched a probe amid a scarcity of eyewitnesses and some conflicting testimony.

In the months after the killing, police identified and questioned several suspects. Authorities ultimately arrested a 28-year-old man who was charged with first-degree murder. Prosecutors presented forensic evidence and witness statements at trial; the defendant was found guilty and received a lengthy prison sentence. Randle’s family attended court throughout the proceedings.
