Among the victims are two wounded children -- a brother and sister who were playing outside of their home.
Their family had just moved, trying to escape violence in their old neighborhood.
Both children only suffered minor injuries and were treated and released from an area hospital.
That shooting was just one of several reported over the weekend.
Between midnight Sunday morning and 4 a.m. Monday, there were shootings at 19 locations in the city of Chicago.
Three people were killed in that time frame, including a man in the 7400-block of South Vincennes Avenue.
The children were shot and wounded in the 5100-block of South Calumet.
So far, no one is in custody for shooting and wounding the 10-year-old brother and 13-year-old sister.
Chicago police continue to search for their attacker.
On Monday afternoon, 10-year-old Tremon Hill carefully ventured outside to tell how he and his 13-year-old sister Anamica Hill narrowly survived their brush with weekend gun violence.
"When I tried to get up, I fell," shooting victim Tremon Hill said.
The attack happened Sunday afternoon as the siblings played in the front yard of their Washington Park neighborhood home.
That's when the children say a shoot-out erupted between two groups of men.
"I heard 10 shots," said witness Jasmine Hill.
The boy sustained a graze wound to the lower back, while doctors opted not to remove the bullet that struck his sister in her arm.
Both brother and sister were treated and released at an area hospital.
"It sounded like firecrackers," shooting victim Anamica Hill said.
"It's crazy. I just thank God that they're still alive today," said the victim's uncle Shawn Hill.
Relatives are outraged over the incident, as is 3rd Ward Alderman Pat Dowell, who visited the family Monday morning.
"We need more officers in the street. The fact that we're getting some special attention from some zero tolerance squads is not enough," Dowell said.
The children's mother, who asked ABC7 to obscure her identity, is just glad none of her other five children were hurt.
"I'm afraid because, truthfully, I don't know if they were shooting at me or my kids," said the shooting victims' mother.
On Monday afternoon, police investigators would not say if video surveillance cameras attached to the building caught the attack, but confirm the children were not the intended targets.
"We don't want the incident to take place in the first place. That's what's most important right now. When you have children that are shot, they are definitely the innocent victims in this situation," said Chicago Deputy Police Chief Eddie Welsh, Area 1.
The family had just to the neighborhood from Chicago's Southeast Side three weeks ago to escape the gun violence there.
