The shooting paralyzed the teenager, his mother, Tami Jackson, said.
He remained in critical condition Thursday.
Jackson said her son had a surgery Thursday to repair his pancreas and has had his spleen removed. He also will need back surgery. Her son is on a ventilator to help him breathe.
“He knows he's in the hospital,” Jackson said. “I'm sure he knows what happened, because he was coherent at the scene. As far as him knowing he's paralyzed, he does not.”
Jackson said she would like to be the one who tells her son about his injuries. She hopes anyone with information about the people who hurt her son and others will come forward.
“All I can ask is if you know who did it, come forward, let somebody know,” she said. “I think all victims, from Tuesday, they deserve justice.”
“There are no links to any of them yet,” said Oklahoma City police Capt. Dexter Nelson.
As of Thursday, police had no suspects, he said.
People with information on the crimes are asked to call 911.
