Sergei Magnitsky
An official investigation was ordered in November 2009 by Russian president Dmitry Medvedev. Russian authorities had not concluded their own investigation as of December 2009, but 20 senior prison officials had already been fired as a result of the case. In December 2009, in two separate decrees, Medvedev fired Alexander Piskunov, deputy head of the Federal Penitentiary Service, and signed a law forbidding the jailing of individuals who are suspected of tax crimes. Magnitsky's death is also believed to be linked to the firing of Major-General Anatoli Mikhalkin, formerly the head of the Moscow division of the tax crimes department of the Interior Ministry. Mikhalkin was among those accused by Magnitsky of taking part in fraud.
Opalesque TV released a video on 8 February 2010, in which Hermitage Capital Management founder Bill Browder revealed details of Sergei Magnitsky's ordeal during his 11 months in detention. On 25 June 2010 radio-station Echo of Moscow announced that Russian Ministry of Internal Affairs "Department for Own Security" started investigations against Lieutenant Colonel Artyom Kuznetsov, who has been accused of improper imprisonment of Magnitsky. The investigation was in response to appeal by the Hermitage Capital Management and United States Secretary of State Hillary Clinton. In February 2011, the investigation, which had not yet identified any suspects, was extended to May.
