"So my immediate thought is okay, maybe this was a car bomb. Okay, maybe these guys had something to do with this IED," Wuterich says.
He says Sgt. Sanick Dela Cruz, who was also charged with murder, yelled at the men to drop to the ground.
"Normally, the Iraqis know the drill when you're over there. They know if something happens, they know exactly what they need to do. Get down, hands up, and completely cooperate. These individuals were doing none of that. They got out of the car [and] as they were going around they started to take off, so I shot at them," he tells Pelley.
As the men ran from Wuterich, he says he shot them in the back.
"How does these men running away from the scene, as you describe it, square with hostile action or hostile intent?" asks Pelley.
"Because hostile action, if they were the triggermen, would have blown up the IED. Which would also constitute hostile intent. But also at the same time, there were military-aged males that were inside that car. The only vehicle, the only thing that was out, that was Iraqi, was them. They were 100 meters away from that IED. Those are the things that went through my mind before I pulled the trigger. That was positive identification," Wuterich tells Pelley.
Other witnesses, including Marines, dispute that the men were running. Wuterich was charged with lying that day to the platoon sergeant, saying the Iraqi men fired on the convoy.
When the vehicle was searched, what was found?
"I believe nothing. I don't remember partaking in the search," he said. "But, as far as I know, there wasn't anything found."
And the men were not armed.
"How much time has passed from the moment of the explosion to the time that you killed these five men?" Pelley asks.
"I would say within about two minutes," Wuterich says.
Next, Wuterich went to his fallen Marines in the bombed Humvee. Lance Cpl. Miguel Terrazas, 20, from El Paso, Texas, was the driver.
Wuterich describes what he saw. "Basically a pile of flesh, in essence. That may be a sight I'll never forget. He was missing one of his arms. His legs were completely severed from his body, but they were still attached because for some reason his Cami's didn't rip completely."
In two minutes, one Marine and five Iraqis were dead, but the killing had just begun. Next, Frank Wuterich would lead his men to kill 19 more Iraqi civilians.
