Investigation of assault re-opened. Initial investigation commenced when a Master Sergeant with the 418th Military Police (MP) Detachment located at Camp Bucca, Iraq notified CID that he observed a soldier strike the detainee with an open hand to the back of his head. The detainee was interviewed and denied being assaulted by any soldier. A month later during an administrative review, Assistant Operation Officer noted to reopen the investigation and re-interview detainee. The detainee described being slapped in the right cheek and shocked with a “taser”: “he hit me with the electric gun twice in my arm with two wire needles, and they took me to the doctor who picked up the two wire needles from my arm.” When asked why he didn’t tell CID that story when interviewed previously, he said that he had told CID this story. Agent confirmed that marks on victim’s arm were consistent with a taser shot 4 weeks earlier. Agent’s investigative report refers to two entries from the activities sheet of Camp Bucca dated March 8, 2004 and March 27, 2004 which detailed “use of force against detainees in which detainees were shot.” Investigation concludes victim’s testimony not credible (in part because of his “depression” and prescriptions for “psychological medication”) and that victim was not assaulted by any guards while detained at Camp Bucca, notwithstanding marks on victim’s arm or the other soldier’s testimony. 4833 not required.
