"He never goes anywhere. It's just so shocking for this to happen to anyone," said Juanita Green Bonner, victim's aunt.
His body was found behind a boarded up home in the 6500-block of South Damen in the West Englewood neighborhood.
"It's somebody's child. . .you know, just laying down on that ground, dead. You know, just another life gone," said Eola States, Englewood resident.
Green was found by officers face-down on a set of basement stairs of an abandoned building.
Although witnesses say there were no visible signs of trauma to the body, family members say police told them Darryl had been beaten to death. Investigators at the scene did not confirm any details.
Relatives say the Harper High School student stopped attending class and think he may have been targeted because of his refusal to join a gang.
