2003 and 2004, and ordered to identify photos of Canadians believed to have ties to terrorism. When he told the Canadians that he had been tortured by the Americans into giving false confessions, the Canadian authorities said he was a liar. Khadr later recalled that he had "tried to cooperate so that they would take me back to Canada". In August, the attorneys Rick Wilson and Muneer Ahmad submitted an "emergency motion" asking for the release of Khadr's medical records. Rebuffed, they were given a statement from the Guantanamo naval hospital commander Dr. John S. Edmondson that Khadr was "in good health", and a two-page "Healthcare Services Evaluation". In November 2004, following a meeting with his attorneys, Khadr was interrogated for four days about what he had discussed with his defence lawyers. He has said that during this time, interrogators used "extreme physical force" and refused to allow him to say his daily prayers. During this visit, the lawyers had administered a psychological questionnaire known as the "Mini–mental state examination", which they later gave to Dr. Eric W. Trupin, an expert in the developmental psychology of juveniles in confinement. Trupin ruled that Khadr was suffering from "delusions and hallucinations, suicidal behaviour and intense paranoia", and that his abuse had left him "particularly susceptible to mental coercion", and at moderate to high risk of committing suicide. Their efforts to secure approval by the US for an independent medical examination of their client were not successful by mid-2006. On March 19, 2005, Canadian government officials began a series of regular "welfare visits" to Khadr to monitor his behaviour. He was being held in Camp V, the maximum-security isolation camp, and they had reports that he had thrown urine at guards and was refusing to eat. That year, his older sister Zaynab moved back to Canada from Pakistan to work for better treatment for Omar and his brother Abdullah. In April 2005, Khadr was given another written psychiatric test by his lawyers, which they gave for interpretation to Dr. Daryl Matthews, a forensic psychologist who had been invited to Guantanamo two years earlier by The Pentagon. Matthews concluded that Khadr met the "full criteria for a diagnosis of post-traumatic stress disorder" (PTSD). In May 2005, Khadr announced that he would no longer cooperate with any of the American attorneys on his case. His Canadian lawyers convinced him that he had to retain Lt.
