Stanley Jacoby Mack, 31, was shot and killed on July 17, 2017, in Chicago’s Woodlawn neighborhood. Officers responded about 2:50 p.m. to the 6300 block of South St. Lawrence Avenue and found Mack with a gunshot wound to the head in front of a residence. He and another victim, 26-year-old Jermaine Robinson, were pronounced dead at the scene; autopsies confirmed both died from multiple gunshot wounds and ruled the deaths homicides.

Neighbors described the block as a nice, quiet street and said they heard multiple gunshots they initially thought were fireworks. No arrests had been made at the time of the initial reports, and police were asking the public for information. Little else about suspects or motive was released.

Are there readers who remember anything about that afternoon on South St. Lawrence Avenue or who might have seen or heard something useful?
