Investigators rule out that the top manager of a Russian oil and gas company whose body was found Saturday in Moscow had been killed, the top Moscow investigator said Sunday.

"There is no fact of murder. A check is underway, all circumstances of what happened are being clarified," Anatoly Bagmet said.

Vladimir Kondrachuk, the board chairman of Trans Nafta, was found dead with a gunshot wound in his company's office in the center of the Russian capital Saturday night.

A police source said Saturday that Kondrachuk had most likely committed suicide.

At the turn of the centuries Trans Nafta supplied oil as part of Russia's federal programs and was Russian energy giant Gazprom's oil and gas condensate export operator.

Kondrachuk was a deputy governor of the Novgorod Region in 2004-2007. According to financial magazine Finans, Kondrachuk's fortune was $35 million in 2006.
