Vaughan A. Allison, 20, was killed in a double shooting on May 30, 2013, on the 7000 block of South Normal Avenue in Chicago. He and a 16-year-old boy were sitting on a porch when both were struck by gunfire early that morning; Vaughan was pronounced dead at Stroger Hospital at 6:37 a.m. The juvenile also suffered injuries in the attack.

Vaughan’s death was one of many homicides in Chicago in 2013, a year marked by widespread gun violence that disproportionately affected young men in certain neighborhoods. His killing underscores the human toll behind the city’s homicide statistics that year. Does anyone have information about that block or that morning that could shed light on what happened?
