Oct. 2, 2010 -- On this week's episode of "Brian Ross Investigates," watch extended never-before-seen interviews as ABC News Chief Investigative Correspondent takes you further into the story of U.S. soldiers charged with murdering innocent Afghan civilians and examines growing questions about what the Army knew and when.
An attorney for Corporal Jeremy Morlock, one of the soldiers charged in the case, describes a drug-filled base in Afghanistan, where he said many soldiers were often high during missions.
"Many people at that Fort Operating Base on Ramrod were smoking hash," Waddington said. "Much of the hash smoking that was going on involved hash-laced opium."
There are also allegations that at least one of the soldiers reached out for help back in the U.S., allegedly afraid his life would be in jeopardy if he spoke out on base about the killings.
Chris and Emma Winfield, parents of Spc. Adam Winfield who is charged with pre-meditated murder in the case, take Ross through the calls they say they placed to Army officials, investigatorsand Florida Senator Bill Nelson to ask for help.
"I said my son is in Afghanistan. . . . He's in the front lines," Chris Winfield said of the messages. "There's a rogue sergeant out there apparently killing innocent victims. And my son found out about this. And they're threatening him because he might say something. And I said you gotta get him out of there. You need to call me back, please."
The Army issued a statement saying that the Winfields never called the Army's inspector general and failed to leave a message with the criminal investigations unit at the base.
A spokesperson for Senator Nelson said they have no record of the Winfields leaving a message, even though the parents saying phone records show they placed a one minute phone call to Nelson's Tallahassee office Feb. 14, 2009.
