Specialist Jeremy N. Morlock, also accused in the Afghanistan deaths, said Sergeant Gibbs had openly discussed how he might kill Specialist Adam C. Winfield, another one of the accused, who he worried would report the killings.

“There were two scenarios SSG Gibbs told me about taking his life,” Specialist Morlock told Army investigators as part of the investigation into the five soldiers. “The first scenario was going to take him to the gym and drop a weight on his neck. The second scenario was SSG Gibbs was going to take him to the motor pool and drop a tow bar on him.”…

Private Stoner said Sergeant Gibbs “associates with skinheads online.” Specialist Morlock said Sergeant Gibbs had “pure hatred for all Afghanis.” Fingers he is accused of collecting are now part of the evidence in the case, as are a teeth he is said to have pulled from a dead Afghan and bones other soldiers said he dug up.
