According to statements from the accused, some of the men collected body parts from the victims — including fingers and bones — and posed for pictures with their corpses.

Gibbs allegedly encouraged his men to join him in killing civilians, and ordered them to keep their activities secret, an order that Winfield paid attention to.

“I take that man very seriously,” Winfield told the investigator in the interrogation tape. “He likes to kill things. He is pretty much evil incarnate. I mean, I have never met a man who can go from one minute joking around, then mindless killings. I mean, he likes to kill things.”

Asked how he thought Gibbs would have responded had Winfield refused to participate in the killing, Winfield said, “I think — one, he wouldn’t have kept me in the loop on things and, if they had thought I had ratted, they would have come after me.”
