Russian media reported that Ravil Maganov, the chairman of the board of Lukoil, Russia’s largest private oil company, died on Thursday after falling from a window at a hospital where he was being treated. TASS, the state news agency, reported that an unnamed law enforcement source said Maganov had killed himself. Maganov was hospitalized after suffering a heart attack and was taking antidepressants, TASS reported. Lukoil is one of the few companies to have publicly criticized Russia’s invasion of Ukraine, calling for an end to the conflict in March. More than half a dozen other oil executives have died this year under undisclosed circumstances. Here are the Russian oil executives who have mysteriously died in the past nine months: Leonid Shulman Leonid Shulman, a top executive at Russian state energy company Gazprom, was found dead of a reported suicide in a country house in the village of Leninsky on January 30. Russian media reported that a suicide note was found at the scene. The note reportedly said Shulman was in excruciating pain with a broken leg. Alexander Tyulakov Alexander Tyulakov, another top Gazprom executive, was found dead in the same village nearly a month later in a garage. An independent Russian newspaper, Novaya Gazeta, reported that his death appeared to be a suicide. He was also allegedly seen being beaten the night before his death. Novaya Gazeta reported that Leninsky is considered an exclusive property for top Gazprom executives. Michael Watford Ukrainian-born oligarch Mikhail Watford, who became a billionaire through the oil and gas industry, was found dead three days after Tyulakov at his home in England. Local British officers reportedly said at the time that they considered his death unexplained but not suspicious. Vladislav Avayev Vladislav Avayev, a former vice chairman of Gazprombank, one of Russia’s largest banks with ties to the energy industry, was found dead in his Moscow apartment along with his wife and daughter on April 18. Police reportedly found a pistol in Avayev’s hands, leading them to consider the incident a murder-suicide. Sergei Protosenya A similar incident occurred a day after Avayev’s death, when Sergei Protosenya, a former vice president of Novatek, a Russian gas company, was found hanged while his wife and daughter were found stabbed to death, according to Radio Free Europe, a US government-sponsored media. They were found in a villa in Spain. Police were investigating the death as a murder-suicide, but Protosenya’s son dismissed the theory, saying his father was not a murderer and would never harm his family, British tabloid The Daily Mirror reported. Alexander Subbotin Former Lukoil executive Alexander Subbotin was found dead in May in the basement of a house near Moscow. TASS reported that Subbotin lost consciousness as a result of a heart attack, and the police launched a criminal investigation into his death.
