A Chicago man with an AK-47 tattooed to his forehead has been charged in the shootings of a teenage boy and a 22-year-old man in the city’s Uptown neighborhood, the Chicago Police Department reported Wednesday.

Kelsky Patterson, 20, who lives in the Kenwood section on Chicago’s South Side, was charged with aggravated battery and discharge of a firearm in the Aug. 31 shooting that critically injured 14-year-old Isaiah Johnson, who was struck twice in the head, the Chicago Sun-Times reported. A 22-year-old man was also hit by a bullet and treated and released from a local hospital.

The shooting was believed to be gang-related, police told DNAinfo Chicago. Though Isaiah, who went by the nickname “Li'l Polo,” was not in a gang, his friends were, according to Chicago activist Anthony Doss.

Patterson was sitting on a bicycle at an Uptown intersection when he allegedly opened fire, according to the Sun-Times. He’s scheduled to appear in bond court Thursday.
