"I just want to wake up and see my son walk through that door, but it ain't gonna happen," Nikkia Oliver, victim's mother, said.
Green, 15, was one of dozens of young people at a home in the 2400-block of Gilboa early Sunday morning. His mother said he'd just arrived at the party.
"He didn't even make it into the house. He was on the sidewalk where the bushes where he fell at. That's where he was standing," Oliver said.
Zion police said a 26-year-old woman was also injured. Her injuries are not considered life threatening.
Police are searching for the gunman, they don't know what led to the shooting. No arrests have been made.
Green had just moved to Zion after living with his father in Texas. He was a sophomore at Zion-Benton Township High School. He was just getting acquainted with his teachers and classmates.
"To think of a young man, losing his life so tragically it's hard to fathom. Our condolences go out to his family and friends and everyone in the community who was affected by it," Dr. Chris Clark, superintendent at Zion-Benton Township, said.
"He was a good kid. He was real smart. He loved football, basketball," Tonya Bell, victim's godmother, said.
"My baby didn't deserve this. I was supposed to be going to a graduation, to a prom...I not supposed to be going to a funeral for no 15-year old. I'm not," Oliver said.
