Because no one called 911, it is unclear how long the teen was fatally injured.
CHICAGO (WLS) -- A 13-year-old was found shot to death after his mother reported him missing.
The boy was found shot in the head at about 2:10 a.m. in the backyard of an apartment building in the 1500-block of South Kildare Avenue.
He was a student at Mason Elementary School in North Lawndale.
The victim's mother went to the police station around 2 a.m. Monday, according to 24th Ward Alderwoman Monique Scott.
Scott said after she reported him missing, officers went back to the area where he was last seen and found him dead.
However, no one called 911 to report the shooting , meaning it is unclear how long the teen had been lying there.
The area used to be a ShotSpotter location, until last September, when the city ended it's contract with the gun shot detection company.
"Speaking with my commander he was like ', you know, if my officers had ShotSpotter we could have located him sooner. And they went off of whatever information they gathered to find this boy'," Scott said. "We don't know if his life could have been saved."
Mourning the boy's loss today is Chrision Rasberry, who says the teen played touch football at the Chicago Park District just a block away from where he was found dead.
"He's not a bad kid," Rasberry said. "I try to get the kids in the area involved, as much as they can be, in terms of sports. I literally just wanted the best for him."
Area Four detectives are investigating and no one is in custody.
