After that November raid on her home, Caddick’s whereabouts were unknown — at least until February, 2021. According to Yahoo! News, that’s when a decaying human foot found inside a sneaker washed up some 400 km away from where she was last seen in Sydney. The remains were later found to be hers, according to ABC Australia, leading to theories Caddick most likely died by suicide.

But, much like other facets of Caddick’s life, the explanation may not be so simple. As reported by ABC Australia, authorities are now considering the theory that Caddick was alive much later than initially suspected, given the condition of the remains, which suggested a much more recent death.

Or — there’s the possibility Caddick isn’t dead at all. Though the foot has conclusively been proven to be hers, some speculate she could just be running a new (and extremely alarming) scam: faking her own death. New South Wales Police Commissioner Mick Fuller told The Sun that when it comes to serial scammers, it’s best to keep all options open. “There’s always a chance she cut her foot off and is still alive,” said Fuller, “but that’s pretty fanciful but nevertheless we haven’t closed this case.”
