Kazbek Dukuzov, 39, is a businessman and boxer from Chechnya who has been linked to the 2004 killing in Moscow of U.S. journalist Paul Klebnikov. He was acquitted by a jury in 2006. A retrial the following year was suspended as Dukuzov could not be found. Russian authorities have also accused Dukuzov in the murder of Chechnya's former Deputy Prime Minister Jan Sergunin.
