Sixteen-year-old Joseph Brewer, an African American male, was shot and killed on July 14, 2013, at a Chicago Housing Authority complex on the 10500 block of South Oglesby Avenue. Surveillance footage showed two men pursuing Brewer through the complex; one of them opened fire, striking Brewer multiple times. He suffered eight gunshot wounds to his legs and back and was pronounced dead less than an hour later at Northwestern Memorial Hospital.

One of the men in the footage was later identified as 26-year-old Aries Sanders. Sanders was arrested and charged with second-degree murder. Court evidence included surveillance video that showed Sanders and another man arriving with a gun case, the other man carrying a large gun partially covered by a shirt and firing several shots before both fled. Sanders was arrested at his workplace as a postal worker and was found guilty after a bench trial; he received a five-year prison sentence, with credit for 963 days already served in Cook County Jail. The other suspect involved has not been apprehended or charged.

Does anyone have information about the second man seen on the surveillance video or details that could help investigators locate him?
