Wagner Group founder Yevgeny Prigozhin died on 23 August 2023 when a private Embraer Legacy 600 aircraft crashed between Moscow and St Petersburg, killing all ten people on board, including Wagner commander Dmitry Utkin and senior figure Valery Chekalov. The crash occurred exactly two months after Prigozhin led the June 2023 Wagner mutiny — a short-lived armed march on Moscow that ended with a negotiated deal brokered by Belarusian president Alexander Lukashenko. Putin offered public condolences. A Wall Street Journal investigation published in April 2024 reported that Western intelligence attributed the crash to an onboard bomb, with FSB involvement. No Russian investigation has produced a transparent public finding.
