The suit , filed on behalf of the nine plaintiffs last year by the American Civil Liberties Union and Human Rights First , also names as defendants three officials responsible for running military prisons in Iraq and Afghanistan : Lt. Gen. Ricardo S. Sanchez , the former top commander in Iraq ; Col. Thomas M. Pappas , who was the top military intelligence officer at Abu Ghraib , the American-run prison in Iraq ; and a former brigadier general , Col. Janis L. Karpinski , who before her demotion to colonel was the military police commander at Abu Ghraib .
