A group of three robbers, at least one of them armed, attempted to rob a man at a Chicago gas station on Monday night. What they didn’t know is that they were holding up an off-duty sheriff’s sergeant who was carrying a gun of his own.

With a gun pointed at his gut and surrounded by criminals, the sergeant made the decision to fight for his life rather than hope he would not be harmed or, even worse, killed.

He seems to hand something over to the crooks and then proceeded to fumble for money with his left hand while sneakily preparing to draw his firearm with his right.

It happened faster than the 16-year-old gunman could react and the sergeant shot the robber at point-blank range. The armed robber fell to the ground as the other two criminals ran for their lives. The officer first turned to the accomplices to make sure they were no longer a threat and then trained his firearm on the injured suspect and kicked his gun away.

Retrieving his phone from his car, the sergeant dialed 911. The 16-year-old robber, identified as Deonta Dewight Mackey, was shot in the head and pronounced dead on the scene.

That entire dramatic scene was captured on surveillance video at a Citgo station across the street from Gately Stadium in Chicago at around 10 p.m. on Monday.

The unidentified sergeant was reportedly uninjured in the incident. Police told the Chicago Tribune that they are still searching for the two other suspects.

“The surveillance video shows a man, a gun in his right hand, running up to the sergeant and pointing the gun at him. The sergeant backs way, drops the nozzle and raises his hands, according to the video. Two other men run up and join the gunman, according to the video,” the report adds.
