A British conspiracy theorist found dead in Poland had been about to publish claims of a global black magic ring involving politicians and celebrities. UFO expert Max Spiers was found dead on a sofa of the Warsaw flat he was staying, with claims from friends he vomited a black liquid" and may have been poisoned. The 39-year-old, who had two children, was ruled to have died from natural causes though his mother claims no post-mortem examination has been carried out on his body. Mother Vanessa Bates also said she received a chilling message just before his death saying: "Your boy's in trouble. If anything happens to me, investigate." Today, Mr Spiers' girlfriend Sarah Adams [stated that] the couple had both received death threats in the weeks before the tragedy. Miss Adams, 31, said: "We were used to getting death threats or stuff like that from people, but I think this time it seemed rather real. He was going to expose black magic." She said: "He was going to expose some of the stuff that he was working on involving political leaders and celebrities. We had both been due to go to a conference to speak about it."
