Just after 1 p.m Wednesday, Cook County deputies arrived on the scene.
They discovered a 13-year-old boy had suffered a gunshot wound and died.
His body was found lying by a love seat near the front door.
His 14-year-old brother pulled the trigger.
And tonight, those in the Hemp Springs Circle neighborhood are wondering how a tragedy like this could happen.
The boys neighbor, Elizabeth Truss, believes the shooting was intentional.
"The extensive knowledge this kid had of guns and shooting 'em, and how to use them," said Truss. "This is not an accident."
Her 13-year-old grandson, Dalton, was close friends with the boy who died.
Deputies say the victim was shot in the face by his brother.
And their father was not home.
"He always told my grandson how scared he was of his brother," said Truss. "And he told me that he didn't like being home with him because he would always hurt him, all the time."
"Knowing the kids like I do, it was just unbelievable," said Seth Mancil, a bus driver with the Cook County School system. "That something would happen. This is a very quiet neighborhood."
Mancil has been driving the boys to school for about six years.
He's says he's had to reprimand the older brother several times.
"[He] seems not to take orders very well," said Mancil. "He'll do things without permission first. And you'll have to correct him."
Neighbors are wondering whether the boy meant to harm his little brother, or if they were just fooling around.
The older brother, whose name has not been released, is charged with involuntary manslaughter.
He's at Memorial Hospital of Adel for evaluation.
Investigators say the older boy said he was sorry and quote "I am going to prison for the rest of my life."
