A witness called by the defense of a Marine accused of assaulting three Iraqis was told he could face criminal charges for allegedly lying. Lance Cpl. Andrew Kraus was read his legal rights Saturday and told he might be charged with making a false official statement and committing perjury during his testimony in a hearing for the accused officer, 2nd Lt. Nathan Phan. The allegations against Kraus came from the lead prosecutor Maj. Donald Plowman. Hearing officer, Lt. Col. William Pigott, agreed, the North County Times newspaper reported Saturday. The action came after Kraus testified he had no recollection of meeting with the prosecutor in August, nor any memory of telling Plowman during that session that his sworn statement that implicated Phan in the assault was accurate.
