To address doubts, Putin launched a Duma parliamentary investigation led by Alexander Torshin, resulting in the report which criticised the federal government only indirectly and instead put blame for "a whole number of blunders and shortcomings" on local authorities. The findings of the federal and the North Ossetian commissions differed widely in many main aspects. Deputy Prosecutor General Vladimir Kolesnikov, sent by Putin in September 2005 to investigate the circumstances, concluded on 30 September that "the actions of the military personnel were justified, and there are no grounds to open a criminal investigation."
