The gun was a BB gun, but the officer didn't know that at the time.
It all happened Saturday. What could have been a horrible tragedy like others seen around the country was by avoided by a split-second judgment call.
"The call came out, then I started heading north on Cockrell Hill," said 16-year veteran Officer Ben Luna, who was first to respond to a 911 call about three teens seen with a gun.
As Luna pulled up to the scene and saw the three, one of them, in a gray sweatshirt, is seen on dash cam looking back and seeing Luna. Then, it appears the teen moves something near his waistband.
"That's what, in law enforcement, we call a furtive gesture," said Duncanville Assistant Police Chief Brian Heard. "It's highly concerning, particularly given the comments on this call."
Luna exited his squad car, yelling commands at the teens.
Luna: "Hey! Get your hands up now! Get your hands up now! Get on the ground! Get on the ground now! Get on the ground!"
Teen wearing gray: [inaudible]
Luna: "No, I don't care! Get on the ground!"
Teen wearing gray: "Look, it's fake…[inaudible]"
Luna: "Get on the ground now! Don't! Get on the ground now!"
The trio was not obeying commands.
"They're fixing to either pull the gun out or they don't really care what…what I'm saying," Luna said he was thinking as the incident was happening.
Even though the teen said the gun was fake, Luna wondered if "he just trying to distract me looking at him, and these two could pull out a weapon. I'm not for sure."
"And your heart's pumping now?" asked FOX 4's Shaun Rabb.
"Yes, it is," said Luna.
Chief Heard says that even though the teen approached Luna with his hands up, the officer was at a disadvantage, because action always beats reaction.
"Even though the officer has his gun drawn, he's on target," said Heard. "If this man chooses from this position to draw and fire, he can draw and fire before the officer can see that, perceive that and stroke that trigger."
Finally, the teen follows instructions and goes to the ground.
Heard says the BB gun that the teen had is a replica of a Beretta 92F that looked very real, so quickly determining whether or not it were real or fake would be difficult.
For Officer Luna, it was a closer than close decision.
"This could have been bad for that young kid," said Luna. "I'm so happy that I didn't have to pull the trigger."
Duncanville police say what was avoided was the kind of tragedy that took place in Cleveland in Nov. 2014, when 12-year-old Tamir Rice was shot by a Cleveland police officer.
Rice had a BB gun.
