康克由
Kang Kek Iew was the first of the five brought before the tribunal. His hearings began on 17 September 2009 and concluded on 27 November 2010. Seven areas of relevance resurfaced frequently during Kang Kew Lew's trial: issues relating to M-13, the establishment of S-21 and the Takmao prison, the implementation of CPK policy at S-21, armed conflict, the functioning of S-21, the establishment and functioning of S-24; and issues relating to character of Kang Kek Iew himself. His lieutenant Mam Nay, the feared leader of the interrogation unit of the Santebal, gave testimony on 14 July 2009 and, although implicated in hands-on torture and execution along with Duch, he was not charged.
