(ANSA) – ROME, MAY 09 – Another mysterious death among Russian billionaires: the former CEO of Lukoil, the billionaire Alexander Subbotin, died after undergoing a treatment with toad venom, during a session with a shaman in Mytiszcze. This was reported by the Polish website Onet, citing a news item in the Moscow Times. Subbotin allegedly died last weekend with his wife undergoing a treatment – which he regularly resorted to – which involved wounds, caused by cuts, in which toad poison is injected to strengthen the immune system. After he had felt ill, the shaman and his wife did not want to call for help – the media reported – deciding to resort to a sedative based on natural herbs. (HANDLE).
