Alexander Tyunin, the 50-year-old executive at Khimprominzhiniring, a subsidiary of Russia's state nuclear corporation Rosatom, was found dead in the Moscow region settlement of Kokoshkino. According to the Sun website, his body was discovered near his car on a roadside close to a forest. A rifle and a handwritten note were found nearby. Preliminary investigations suggest suicide, with the note indicating that Tyunin had been battling depression for five years.

Joint Stock Company "NPK "Khimprominzhiniring" is part of the Russian state corporation "Rosatom". Khimprominzhiniring is the only producer of carbon fiber in Russia, from which aircraft fuselages, wings, tail stabilizers, and other parts are made, according to the UNN.

According to the UNN website, the note said, "I did it myself, I'm tired of fighting depression for the fifth year, it's getting worse and worse, I have no strength." His death adds to a series of unexplained fatalities among high-ranking executives in Russia's energy, nuclear, and industrial sectors since the onset of the war in Ukraine. Skepticism has arisen after reports revealed that the note appeared in Russian media before any official confirmation of Tyunin’s death.

According to the Sun website, an unnamed source remarked, “There was a clear intention to present this as a suicide before any formal investigation had even started.”

In July, Russian Transport Minister Roman Starovoit was reported to have died from a gunshot wound, with some Telegram channels connected to Russian security forces also citing suicide as the official cause. Earlier in March, former MP Buvaysar Saitiev, 49, reportedly fell from a window in Moscow. He was discovered in critical condition and subsequently passed away.
