Here's the official word from Col. Steven Boylan, Public Affairs Officer for U.S. Army Commanding General in Iraq David Petraeus:
To your question: Were there any truth to what was being said by Thomas?To summarize: Beauchamp is a liar, and they're letting his CO punish him. And I'd imagine that his CO is gonna take a real dim view of Beauchamp's actions.
Answer: An investigation of the allegations were conducted by the command and found to be false. In fact, members of Thomas' platoon and company were all interviewed and no one could substantiate his claims.
As to what will happen to him?
Answer: As there is no evidence of criminal conduct, he is subject to Administrative punishment as determined by his chain of command. Under the various rules and regulations, administrative actions are not releasable to the public by the military on what does or does not happen.
