An Arizona public radio station has uncovered new details on the death of one of the first female US soldiers to die in the Iraq war. KNAU Radio reports Army Specialist Alyssa Peterson took her on own life after objecting to interrogation techniques used on Iraqi prisoners. Peterson was assigned to a US air base in Tal-Afar. She died on September 15, 2003 from what the military called a “non-hostile weapons discharge.” But newly uncovered documents say investigators actually concluded Peterson shot and killed herself with her service rifle. The documents also show Peterson’s death came after she refused to take part in further interrogations after just two days. Military officials refused to describe what techniques Peterson had objected to and said all records of them had been destroyed. Specialist Peterson was twenty-seven years old.
