2 shot including 13-year-old boy in Auburn Gresham

CHICAGO (WLS) -- Two people were shot, including a 13-year-old boy, in the city's Auburn Gresham neighborhood Friday afternoon, Chicago police said. Neither were intended targets.

Police said around 4 p.m. in the 7900-block of South Ashland Avenue, an argument inside a gas station escalated into a shooting.

"It's sad. It's sad. But it's the way life is now," said Ralph Kendall, who works at the gas station.

Police said there was a physical altercation between two people in the gas station. A third person pulled out a gun and fired shots.

A 28-year-old man inside the gas station was struck in the ankle. A stray bullet flew through the window of a #79 CTA bus on the street outside the gas station and struck a 13-year-old boy in the jaw, critically wounding him.

"I didn't see the shooter because my back was to him. But when I heard the shots I did like everybody else: I ran," Kendall said.

The 13-year-old boy was taken to Comer Children's Hospital in critical condition. As of 5:30 p.m. he was undergoing surgery and police said he is expected to survive.

"The 13-year-old right now is in critical condition. He was shot in the jaw. He is currently in surgery but expected to survive," said Chicago Police Commander William Bradley.

The 28-year-old man was taken to Holy Cross Hospital in stable condition.

Police are now searching for the shooter.

"We have increased the patrols, and we intend to do everything we can to bring him to justice," Cmdr. Bradley said.

"It's a sad thing nowadays that teenagers can't ride the bus, and all these guns and violence and stuff. It leads to this," Kendall said.

Police said it's unclear what that fight was about that led to the shooting. Investigators say they're working a number of leads
