CHICAGO (CBS) — A 70-year-old man was shot and killed Tuesday night in the Park Manor neighborhood, and might have been the victim of a stray bullet from a shootout between two cars.

Police said the Leroy Moore was walking out of a store at 71st and State around 8:20 p.m. when shots rang out and he was struck in the chest. Moore was taken to Stroger Hospital, where he was pronounced dead.

Crisis responder Andrew Holmes said the shooting might have begun on 63rd Street near the Dan Ryan, when a gold Buick LaCrosse and a blue SUV exchanged gunfire.

Holmes said witnesses observed the altercation, and have been working with investigators.

“They’re trying to determine whether those in that vehicle came down this way, and were shooting at each other, then a stray bullet hit the [victim] who was walking down the street after he left out of a store, and then he felt pain in his chest and told a friend of his that he was hit,” Holmes said.

Moore’s son, Shaun, said his father was “a great man.”

“He was a great granddad to my daughter. He was a loving husband. I really respect my dad,” Shaun said.

Out of respect for his father, Shaun said he planned to go to the Cook County morgue to identify his father’s body. It’s something he and his brother said they’ll do for themselves and for their mother.

“I kind of understand she don’t want to go in there,” Shaun said.

Now, as he prepares to say goodbye to his dad, Shaun said he hopes his father’s killers will soon say goodbye to freedom.

“I just hope they catch the people who did it. That’s all you can do,” he said.

No one was in custody Wednesday morning. Area Central detectives were investigating.
