Sergio Zaragoza was 28 when he was shot on the afternoon of September 11, 2016 in Chicago’s Hermosa neighborhood. An argument on the 1600 block of North Karlov Avenue turned physical; police and the Cook County medical examiner say a male approached during the scuffle, produced a gun and fired once into Zaragoza’s chest. He was taken to Mount Sinai Hospital and pronounced dead at 3:47 p.m.

Authorities noted the incident might have been domestic in nature and that Zaragoza lived a block north of where the shooting occurred. In January 2017 Chicago police announced charges against Tony T. Browley, alleging Browley walked up during the fight and fired the fatal shot. Court records show Browley was ordered held without bond. Memorial notices and community records later listed services and preserved Zaragoza’s name and date, marking how a late-summer argument became a fatal encounter.

Did anyone in Hermosa that day see the confrontation or have information about Zaragoza’s last hours?
