When Winfield told his parents in February 2010 about one of the incidents via Facebook, he also told them, "I want to do something about it. The only problem is that I don't feel safe here telling anyone."
He said there was a rumor that he was going to talk and "the threats are already coming my way."
In Afghanistan, according to other soldiers, Gibbs was becoming suspicious of Winfield.
An Army investigator asked Cpl. Morlock during his taped confession if he thought Gibbs was serious about maybe having to "take out" Winfield.
"Oh, f___ yeah, for sure, definitely," answered Morlock.
"So you didn't take that as a joke," said the investigator, "or like maybe it was just bull____."
"[Gibbs] doesn't bulls____," said Morlock. "He doesn't need to."
Adam Winfield's parents claimed in an interview with ABC News that in February they warned the Army by phone that soldiers in their son's unit were thrill killing civilians. One of the murders with which Winfield and the other soldiers were charged took place after the calls.
After an internal investigation, the Army has issued a statement saying that the parents of a soldier charged with murdering unarmed Afghans never called the Army's inspector general. The Army acknowledges that Christopher and Emma Winfield did call several numbers at their son's Army base in the U.S., and had an extended conversation with someone at the base's command center, but says the Winfields failed to leave a message with the criminal investigations unit at the base.
"The Army takes very seriously recent media reporting in which the father of Spc. Adam Winfield said he alerted the Army to allegations of crimes by Soldiers deployed to Afghanistan," said the Army's statement. "We have not yet found any evidence to indicate Mr. Winfield called the office of the Army's Inspector General."
"We examined the phone records of the Winfield family, with their consent. Based on this examination we have determined that another federal agency's Inspector General was called by mistake."
