In June 1980, 56 year old Zigmund Adamski left his home on home to go and grab some food shopping, and then he never came home - his body would later be found under baffling circumstances, that to this day, no one has ever been able to make sense of. The strange, strange situation around Zigmund’s death has led to countless theories over the years, none of which quite make sense but there is one theory that people seem to focus on more than the rest: alien abduction.
