The most recent shooting took place in near W. 63rd Street and S. Artesian Avenue in Marquette Park. The second shooting was near E. 71st Street and Jeffery Boulevard in South Shore.
In the South Shore incident, five males and one female were standing outside when an unidentified occupant of a black SUV drove past their location and began shooting around 8:45 p.m. Sunday, according to Chicago police.
Nyoka Bowie, 37, was shot six times and died at the University of Chicago Medical Center, where some of the victims were taken. A 15-year-old boy, who was shot twice, was also one of the male victims.
"She was a hard working person," who looked out for everyone, her nephew Ron Williams said.
Williams said Bowie had no children of her own, but often watched his young kids. Friends said she preferred to go by "Yogi," and normally avoided outdoor gatherings for safety concerns.
"We'll have all our parties inside 'cause it was safer that way," said Valencia Scaife, friend. "It was just this one day she was caught in the wrong place at the wrong time."
Police said they are still early in their investigation, talking to witnesses and looking for video in the neighborhood.
There were 11 victims in the Marquette Park incident after three people walked up from an alley to a gathered group and began shooting. Six men and five women were hit with gunshots around 11 p.m. Sunday. One of the women died.
"Hundreds of people looking around, onlookers, family members, people who are injured. Just another night of mayhem in Chicago, summer night. It shouldn't be like this, it shouldn't be like this, but unfortunately, it looks like this may be our summer, definitely going to be our Fourth of July," said Pastor Donovan Price, Street Pastors.
A source said some of the victims are known to police and have gang ties.
At least 74 people were shot and six people were killed since Friday through Sunday 11:59 p.m.
