"Your boy's in trouble. If anything happens to me, investigate."
Vanessa Bates had no reason to believe her son Max Spiers was being anything other than paranoid when he sent her this message in July.
The 39-year-old was an expert in conspiracy theories after all -- and he'd just embarked on a trip from her home in Canterbury in the UK to Poland, where he was due to give a talk on conspiracy theories and UFOs.
But days after sending his mom the spooky text message, his dead body was discovered on a couch in the Eastern European country, The Mirror reports.
He was ruled to have died from natural causes -- even though there was reportedly no post-mortem conducted.
But his 63-year-old mom is determined to fulfill her son's final request.
His research into UFOs and "government cover-ups" meant he had plenty of enemies, Vanessa says.
Max, who had been living in the US for the past few years and come to visit her before jetting off to Poland, started looking into the lives of well-known politics, business and entertainment personalities.
"I think Max had been digging in some dark places and I fear that somebody wanted him dead," the English teacher said.
According to MailOnline, Max had been working with science fiction writer Monika Duval, whom he had reportedly been staying with in Poland.
"Max was a very fit man who was in good health and yet he apparently just died suddenly on a sofa," Vanessa told Polish press at the time.
"All I have is a death certificate from the Polish authorities that it was from natural causes, but no post-mortem was done so how can they tell that?
"They are also refusing to release any paperwork about it to me because, absurdly, I don't have his written permission."
His fans online seem to agree, clamouring for details surrounding the father of two's death to be released.
"This young man was murdered in Poland," one of Max's Facebook followers wrote on his page. "Seemingly vomited black blood. They got to him!"
"I hope he does not pass without an investigation.... however, we already know the results of that."
Project Camelot blogger Kerry Cassidy claims "Both the doctor who examined Max and Police who came to the villa [and] left the body behind in spite of the fact that they believed Max had died."
"What kind of officials do this? The entire circumstances are suspicious and I urge everyone to encourage Monika to release the details about what really happened to the public and call for an autopsy."
Another conspiracy theorist, from HPANWO Voice, weighed in: "Even the mainstream media has picked up on this, with one of their typically tongue-in-cheek ridicule-fests. The very term "conspiracy fans" indicates that they're not interested in objectivity."
