Ronald Holliman, an 18-year-old African American male, was killed on June 4, 2014, in Chicago’s Austin neighborhood on the 4900 block of West West End Avenue. He and several others were on a home’s front stoop when three gunmen came from an alley and opened fire. Holliman was struck multiple times — in the buttocks, leg, thigh, and knee — and was pronounced dead shortly after arrival at Mount Sinai Hospital.

Three other males were wounded: a 21-year-old shot in the left leg, arm, abdomen, back and left flank; a 26-year-old shot in the chest, back, abdomen and flank; and a 17-year-old who sustained a graze wound to the right hip and declined treatment at the scene. Investigators recovered numerous shell casings from three different guns: two 9 mm pistols and a .45-caliber pistol.

Police arrested 27-year-old Reginald Jackson on June 8, 2014; he was initially taken on weapons charges when officers found him and two others in a car with two 9 mm handguns. Ballistic testing later linked those weapons to the stoop shooting, and Jackson was charged with murder and attempted murder and held on $600,000 bail. What additional information can anyone who knew Holliman or the victims provide to help clarify what happened that night?
