Sergei Leonidovich Magnitsky (8 April 1972 – 16 November 2009) was a Russian accountant and auditor whose arrest and subsequent murder in custody generated international media attention and triggered both official and unofficial inquiries into allegations of fraud, theft and human rights violations. Magnitsky had alleged there had been a large-scale theft from the Russian state sanctioned and carried out by Russian officials. He was arrested and eventually died in prison seven days before the expiration of the one-year term during which he could be legally held without trial. In total, Magnitsky served 358 days in Moscow's notorious Butyrka prison. He developed gall stones, pancreatitis and a blocked gall bladder and received inadequate medical care. A human rights council set up by the Kremlin found that he was beaten up just before he died on 16 November 2015.
