CHICAGO — A man with a concealed-carry license shot and killed an armed robber Wednesday night in Grand Boulevard, police said.

At 8:20 p.m., the man was sitting in a car with another man in the 4300 block of South State Street when two men with guns walked up and tried to rob them, said Officer Ana Pacheco, a Chicago Police spokeswoman.

One of the men in the car, 32, fired his gun, hitting one of the robbers, Pacheco said.

Treamel Gray, 23, one of the alleged robbers, was shot in his head. Gray, of south suburban Flossmoor, was pronounced dead at the scene. He was identified Friday by the Cook County Medical Examiner's office.

The other robber ran away.

The 32-year-old man had a valid concealed-carry license, Pacheco said.
