Footage taken from a balcony across from the shootouts captured a gruesome moment between an officer and a shooter on the ground.

The footage shows a gunman hiding behind a pillar while an officer approaches him. The officer then tries to take down the shooter by firing a shot into his back, yet the bullet appears to have been deflected by a vest.

The officer is then left completely open to the shooter, who then charges at the officer. The officer attempted to hide behind a pillar, but the shooter came from behind and shot the officer in the back. Once the officer fell to the ground, the shooter then executes the officer at point blank range.

Witnesses told CNN that shooter appeared to have an assault rifle and was unaware that the officer was behind him. Yet, the officer did not seem to faze the shooter, who swiftly turned and shot the officer while he lay on the ground.

The graphic video of the shooting can be seen below:
