PULLMAN — The gunman shot and killed by an off-duty Cook County Sheriff 's sergeant late Monday night during a gas station robbery attempt has been identified as 16-year-old Deonta Mackey.

The sergeant fatally shot Mackey as he and two other males tried to rob him in the 700 block of East 103rd Street, police said.

The three males came up to the sergeant and demanded his wallet, and one of them pulled out a handgun and pointed the gun at the officer, said Officer Hector Alfaro, a Chicago Police Department spokesman.

As the sergeant handed over his wallet and other valuables, he reached for his gun and shot the gunman in his head, police said. The other two men fled the scene.

Mackey, of the 900 block of East 104th Street, was pronounced dead on the scene at 10:08 p.m., according to the Cook County Medical Examiner's Office.

No other injuries were reported in the shooting, and police recovered a gun at the scene, Alfaro said.

In an email, Benjamin Breit, a spokesman with the sheriff's office, said the sergeant appeared to be the "intended victim of a crime and shot an offender while acting in self-defense."

Breit did not provide more details, saying the investigation into the shooting is ongoing.

NBC5 Chicago obtained surveillance video of the shooting, which shows a gunman pointing a handgun at the sergeant. Watch it here:
