His request was a complete departure from his previous conduct, as he had cooperated with the trial and repeatedly apologized to his victims and their families. His lawyers took different approaches in their closing remarks, with one stating that his client was not guilty and the other asking for clemency. In March 2009, Kaing accepted responsibility and apologized [JURIST report] for his conduct at the detention facility. He is the first of eight ex-Khmer Rouge officials expected to be tried before the ECCC. In April, the pre-trial chamber of the ECCC dismissed appeals by three other former Khmer Rouge officials [JURIST report] to block the extension of their provisional detention. The three prisoners, Ieng Thirith, Ieng Sary and Khieu Samphan, were arrested in November 2007 and face charges of genocide, war crimes, crimes against humanity, murder, torture and religious persecution.
