Two reputed Chicago gang members allegedly executed a 9-year-old boy in broad daylight because they sought revenge on the child’s father’s rival gang, which they blamed for gunning down family members, prosecutors said Tuesday.

Tyshawn Lee, 9, was in his school uniform when three men approached him in the South Side of Chicago in November 2015, prosecutors said during opening statements.

Prosecutors said Corey Morgan and Kevin Edwards kept watch while Dwight Doty lured the fourth grader into an alleyway. They said he promised him a juice box.

Doty then took out a .40-caliber handgun and shot Lee, Cook County Assistant State’s Attorney Margaret Hillmann said.

Two separate trials began for Morgan and Doty on Tuesday. The two alleged members of the Bang Gang/Terror Dome faction of the Black P Stones gang seek to pin the blame on each other for the child’s slaying, reports said. Edwards, who prosecutors claim was the getaway driver, pleaded guilty earlier this month to first-degree murder in exchange for a 25-year prison sentence, according to the Chicago Tribune. He’s not expected to testify against the other two men. – READ MORE
