A 34-year-old Hispanic man identified as Alcaraz C. Reyes was fatally shot in the chest just after dawn on March 22, 2016, in Chicago’s Back of the Yards neighborhood. The attack occurred about 6:15 a.m. in the 5200 block of South Winchester Avenue, steps from where he lived. First responders took him to Mount Sinai Hospital, where he was pronounced dead at 7:08 a.m.

Police sealed the residential block as neighbors emerged to the sound of sirens. Detectives canvassed the street and evidence technicians searched for shell casings and cameras. Reports note additional gunfire on the same block later that evening, but authorities did not say whether it was connected to the morning killing. Contemporaneous reporting and public homicide listings for that date do not show an arrest tied to Reyes’s death. An obituary published that week, under the name Reyes Alcaraz, announced services and described him as a son, partner, and father.

Does anyone who lived on South Winchester Avenue or knew Reyes have information about what happened that morning?
