The article in The Age didn't suggest that the police are stumped. Just that they have a lot of work to do.
Eg: (from The Age)
Ian Wilkinson's recollections about ....
- anyone bringing a dish to the lunch, if so did the dish include mushrooms, was there more than one beef wellington, was there a sauce or anything else that could contain mushrooms
- did the lunch guests forage for mushrooms themselves
- was the lunch a regular event, what was its purpose, were the children there, what did the children eat, was the children's future discussed
SP's recollection of any discussion with EP about the cause of the poisoning
What were EP's internet search history, her reading habits, her TV habits
What do EP's friends and family say
An examination of SP's hospitalisation 14 months prior
Check all Mount Waverley Asian grocers and check their wholesalers who supply dehydrated mushrooms
Leongatha lunch survivor Ian Wilkinson’s recollections will be vital for detectives, as they continue the long-haul investigation after tests confirm the mushrooms did it.
