The death of Max Spiers, who studied UFO sightings, in Poland has set off a flurry of conspiracy theories.
Spiers sent his mother a text message just days before his death several months ago in which he told her, “If anything happens to me, investigate,” as reported by the Telegraph.
The 39-year-old from Canterbury was found dead in Warsaw, Poland, in June. Local authorities said he died from natural causes—a claim his mother denies.
