Lie Detector Exposes Murder

When Sergeant Ryan Weemer applied to be a part of the Secret Service, his background check unearthed something unexpected: a murder confession. While undergoing a polygraph tests, Weemer was asked about the most serious crime he had ever committed. "We went into this house, there happened to be four or five guys in the house. We ended up shooting them, we had to," Weemer said about his time in Fallujah in 2004, when 10,000 U.S. troops stormed the city. He said they hadn't had time to take the men to a detention center because of the deadly house-to-house fighting. Weemer is facing court martial for unpremeditated murder and dereliction of duty at the Camp Pendleton Marine base in California. A week ago, a U.S. soldier was sentenced to 35 years in prison for his part in the execution of four Iraqi prisoners in 2007.
