Newsweek: Putin's key man in the Arctic found dead after falling overboard

The death of a Russian energy executive over the weekend adds to a list of mysterious deaths of high-powered national businessmen since the February 24 invasion of Ukraine.

Ivan Pechorin, 39, managing director of the Corporation for the Development of the Far East and the Arctic, reportedly fell off a boat at full speed and died Saturday near Russky Island in the Sea of Japan in Primorsky Krai, Russia, near Vladivostock, about 5,800 miles east of Moscow.

Pechorin worked under Russian President Vladimir Putin, according to the Russian publication Komsomolskaya Pravda, modernizing aviation in eastern Russia while developing resources in the Arctic in light of heavy sanctions.

Pechorin's last public appearance reportedly occurred at the Eastern Economic Forum, held from September 5 to 8 in Vladivostok, according to Newsweek.

The Daily Mail reported that Pechorin spoke during a session called, "Everyone has their Own Route: The Logistics of a Changed World."

His death follows that of the corporation's former CEO, Igor Nosov, 43, who reportedly died suddenly from a stroke in February.

On September 1, Ravil Maganov, 67, an oil tycoon and former head of Russia's second-largest oil company, Lukoil, reportedly fell to his death from a sixth-floor window of a Moscow hospital. Unconfirmed reports allege that Maganov was "beaten" and "thrown out of a window."

The oil tycoon had previously expressed his opposition to the invasion of Ukraine. Lukoil, meanwhile, said his death came "after a serious illness."
