Mutasim Sulieman, 33, was shot and killed on May 3, 2019, in Humboldt Park, Chicago while closing his cellphone shop, Division Quick Stop and Cellular, at 3657 W. Division Street. Chicago police officers witnessed the ambush and pursued the assailant but did not immediately apprehend him.

Investigators say the killing was a targeted hit arranged by two men then in Cook County Jail, Terran Scott and Deshon Jones, because Sulieman had been a key witness in a 2016 murder that took place inside his store. Prosecutors allege the plot was coordinated through recorded jail calls and that 19-year-old Kyrell Pittmon carried out the shooting. Pittmon was identified by DNA from a face mask left at the scene, phone records, surveillance footage and electronic monitoring data; he was arrested and charged with first-degree murder. Tramell Scott was later charged with participating in the murder, and statements Sulieman made before his death were admitted as evidence against the men who allegedly orchestrated the hit.

Does anyone have information about Sulieman, his store, or the events around closing time that night?
