The teenager, who was shot in the stomach, is scheduled to have surgery on Tuesday.
In all, seven people were injured in the shooting near a liquor store in the 2500-block of East 79th Street on Sunday night. Jamal Harris, 19, and Gregory Glinsey, 53, were shot in the chest. They died at the scene. Harris was found inside the store, Glinsey was outside.
Police say Glinsey was an innocent victim. He had just celebrated his mother's 80th birthday on Saturday.
"They gave him the nickname of 'Alamo.' ... They said he has always been headstrong, he's always sturdy, he was always in control of himself. He was small, but he had a strong mind," Bertha Glinsey said. He leaves behind four children and seven grandchildren. "We always said he made a project out of everything he'd started. He made a project out of it because it had to be complete."
Mourners left cards and balloons near the scene.
"I just pray for those that are deceased or harmed... and I pray there will be a better day in our community for our people. And stop the killing," said Claire Lewis, who works at a nearby church.
Police are looking for the gunman, who they pulled up to the liquor store in beige vehicle and opened fire. Only the 14-year-old remains hospitalized at Comer Children's Hospital. The other four surviving victims, all teenagers, were treated and released by doctors.
Manager Chris Imsaih reopened the liquor store on Monday. He said one of the victims ran into the store after being shot.
"Young kids, they've got guns. They're shooting randomly, they do not know how to act. And then they are killing innocent people," Imsaih said.
