Arturo A Zizumbo, 47, was shot and killed on the afternoon of December 16, 2016, in Chicago’s Brighton Park. He was walking with three teenagers in the 4300 block of South Rockwell Street when a silver vehicle pulled up, two people emerged and opened fire. Zizumbo was struck multiple times and pronounced dead at the scene at about 3:40 p.m. One of the teens, 17-year-old Daniel H. Torres, also died; the other two—a 17-year-old and an 18-year-old—were taken to Mount Sinai Hospital with serious and critical injuries.

Zizumbo lived nearby on South Maplewood. An obituary listed his full name as Arturo Zizumbo Aspera, with arrangements through Martinez Funeral Home and interment in Morelia, Michoacán, Mexico. Police described the attackers only as two unknown offenders who exited a silver car; contemporaneous reports did not announce arrests and later write-ups continued to describe the case as unsolved.

Did anyone in Brighton Park that afternoon see the silver vehicle or the people who got out of it?
