Four people were killed and 14 others wounded when gunfire erupted outside Artis Restaurant and Lounge in Chicago’s River North district late on 3 July. Police said a dark-colored car drove past the crowd gathered for rapper Mello Buckzz’s mixtape release party and someone inside opened fire shortly after 11 p.m., then sped away. The dead include two women, ages 26 and 27, and two men, 23 and 25. Three of the injured remain in critical condition. Investigators have not announced any arrests or a motive, and detectives are reviewing video footage while appealing for witnesses. Mayor Brandon Johnson joined police and fire officials at a previously scheduled Fourth of July safety briefing, calling the attack “senseless” and pledging additional patrols in entertainment corridors through the holiday period. Despite the River North shooting and two other mass-casualty incidents, Chicago recorded nine homicides and 44 shooting injuries over the 3–6 July holiday window—its lowest Independence Day weekend violence in a decade, according to preliminary police data.
