The shocking moment a man shot and killed a gunman in a shootout has been captured on surveillance video - and police say he won't be charged.

A motorist pulled out a gun when Ronald Morales, 43, approached his car at a gas station in Elmwood Park, Illinois.

The men shot at each other multiple times in broad daylight before Morales ran away and the driver sped off.

Morales eventually died from his injuries - but police say they won't be charging the man who killed him because he was acting in self defense.

Police say on April 8, at 4:52pm, Morales made eye contact with a man who was pumping gas into his vehicle.

Morales exited the convenience store at the BP gas station on Grand Avenue in Elmwood Park.

He walked over to the car and pulled out his gun.

By then, the man who had been pumping gas was back in his vehicle.

Morales opened the passenger door of the car and then closed it before speaking to the man inside through the window.

The man felt he was in danger, according to police, and exited his vehicle armed with his own gun - and the two exchanged gunfire.

After about five seconds, Morales ran away, but not before he was hit with bullets, and the other man sped off.

Morales eventually ran away, and the driver sped off, but he was shot too many times and eventually died from his wounds

At the time, police credited the gas station's 'state-of-the art camera system' with providing them clear footage of the afternoon of the shootout.

They say this allowed them to to quickly corroborate information gathered from eyewitnesses, the man who survived the shootout and the vehicle occupants.

Police say that because the man was acting in self defense, they won't be pressing charges.
