Max Spiers, a renowned British conspiracy theorist died in mysterious circumstances in Poland in July

A British UFO expert was sacrified by Polish Satanists as he investigated conspiracy theories, his mum and girlfriend claim.

They say the murky cult had pumped Max Spiers full of drugs before he died in Warsaw in July.

The conspiracy theorist, 39, from Canterbury, in Kent, was found dead on a friend’s sofa.

He texted his mother Vanessa Bates, 63, just days before he died saying, ‘Your boy’s in trouble. If anything happens to me, investigate.’

Mrs Bates, an English teacher, told MailOnline she believes her son was sacrificed by the shadowy cult – and may have been ‘slowly poisoned’.

She said: ‘He was making a name for himself in the world of conspiracy theorists and had been invited to speak at a conference in Poland in July.

‘He was staying with a woman who he had not known for long and she told me how she found him dead on the sofa.

‘But I think Max had been digging in some dark places and I fear that somebody wanted him dead.’

Mr Spiers was staying with friend Monika Duval and was found dead at her property.

Monika was said to be at a book fair in Frankfurt, Germany, last night when MailOnline visited the property.

He reportedly vomited a black liquid before he died.

His girlfriend Sarah Adams, 31, claims he was being held against his will. She said: ‘He was terrified, he wanted to leave. He rang secretly as they wouldn’t let talk. He said they were trying to get away from them.’

Max was ruled to have died from natural causes despite no post-mortem examination being carried out on his body

He made a career out of investigating UFO sightings and alleged cover-ups.

Mr Spiers, a father of two, was a UFO expert. He texted his mother just days before he died – saying: ‘Your boy’s in trouble. If anything happens to me, investigate.’

Of her last conversation with him, Ms Adams, 31, pictured with him, said: 'He was really not well. He wasn't coherent at all. 'I kept telling him, "I love you", and, "You don't sound well".'

His girlfriend Sarah Adams, 31, pictured with Mr Spiers, claims he was being held in Poland against his will. ‘He was terrified,’ she said. He wanted to leave. He rang secretly as they wouldn’t let talk. He said they were trying to get away from them.

Mrs Bates has now claimed she was sent a ‘threatening’ book on devil worship and black magic by Ms Duval.

The black tome, entitled ‘Sacrifice: Magic Behind the Mic’, includes chapters on ‘Illuminati Blood Sacrifices’ and ‘Moloch, Owls and the Horns of Satan’.

She was also mailed a shocking photograph of her son with a head wound, as well as two images of him in a coffin wearing a ‘strange silk suit’, by Ms Duval, she said.

And she explained how when she spoke to the woman on the phone just hours after his death, she could hear ‘satanic rituals’ being conducted in the background.

‘I could hear all this kerfuffle in the background – ritualistic stuff.

‘There were strange suggestions of things that should be done like put milk by this side and get garlic and put flowers and put vinegar and very weird goings on.

‘I could hear it being said. It sounded like rituals going on. Some sort of satanic rituals.’

She added: ’The more you dig, the more questions you have got and the more difficult it is for a mother, because I don’t like the idea of people messing around with his body.’

His mother, Mrs Bates, pictured, told MailOnline: ‘He was staying with a woman who he had not known for long and she told me how she found him dead on the sofa. ‘But I think Max had been digging in some dark places and I fear that somebody wanted him dead.’

Mother shares suspicion of conspiracy theorist son’s death

‘Its absolutely ghastly. I feeling appallingly let down by the Polish police, I feel appallingly let down by the doctor and by the people who did the last interview when he sounds like he’s dying.’

Kent Country Council yesterday confirmed that a post-mortem conducted in the UK had returned an ‘inconclusive’ result – leaving open the option of foul play.

Mrs Bates has said that Max – who attended private school St Edmunds School, Canterbury alongside Orlando Bloom – ’was a very fit man who was in good health’.

Her son was buried in Canterbury cemetery after his body flown home a week after his death.

Mr Spiers had made a career out of investigating UFO sightings and alleged cover-ups in the government.

More recently, he was said to be probing into the lives of well-known figures in politics, business and entertainment.

British conspiracy theorist Max Spiers talks his theories

But his unexplained death, and its subsequent treatment by the authorities, has left many online followers convinced he was killed by government agents.

On one website, Project Camelot, a blogger wrote: ‘The entire circumstances are suspicious and I urge everyone to encourage the release of details about what really happened and call for an autopsy.’

Kent Council said in a statement ‘The Coroner has opened an investigation into the death of Max Spiers, which may or may not result in the need for an inquest.

‘A post mortem was ordered and has been undertaken. However, the results were inconclusive and further tests are being carried out.

When these results have been received, the Coroner will decide whether to continue the investigation and, as part of that investigation, to hold an inquest.’
