The Defense Department's top watchdog has declined to investigate allegations that an American woman working under an Army contract in Iraq was raped by her co-workers. The case of former Halliburton/KBR employee Jamie Leigh Jones gained national attention last month. An ABC News investigation revealed how an earlier investigation into Jones' alleged gang-rape in 2005 had not resulted in any prosecution, and that neither Jones nor Democratic and Republican lawmakers have been able to get answers from the Bush administration on the state of her case. In letters to lawmakers, DoD Inspector General Claude Kicklighter said that because the Justice Department still considers the investigation into Jones' case open, there is no need for him to look into the matter. We're not satisfied with that," a Nelson spokesman said. Jones' lawyers also professed disappointment. Despite deferring to the Justice Department, Kicklighter's office told Nelson it was willing to pursue other questions Nelson raised about Jones' case. Kicklighter agreed to explore "whether and why" a U.S. Army doctor handed to KBR security officials the results of Jones' medical examination, a so-called "rape kit," which would have contained evidence of the crime if it had occurred. In a separate letter, Kicklighter's office said that the State Department had said its security officials had Jones' rape kit in their possession at one point.
