EP: told them (police) she dumped it there a 'long time ago'
EP: revealed she did so after her guests fell ill Link
PI on Under Investigation show: She's decided to go to the tip in Koonwarra [the tip closest to her house], and on speaking with the workers there, interestingly, without saying when did she come or anything like that, one of them stated to us that "I don't know because I wasn't working Saturday morning".

Lunch was on the Saturday, presumably in the middle of the day.
So there is a question of when the dehydrator was actually dumped.
But there is CCTV at the rubbish dump, so the police will know.
So this raises even more questions on her fictional telling of her story that day.
IMO
