Erin Patterson has been found guilty on all counts in a triple murder case that gripped Australia, with a jury finding that she deliberately laced a family lunch with death cap mushrooms.
Patterson, 50, was found guilty of murdering three people and attempting to murder a fourth person. She was charged with killing her mother-in-law Gail Patterson, father-in-law, Donald Patterson, and Gail's sister, Heather Wilkinson, along with the attempted murder of Ian Wilkinson, Heather's husband.
Patterson cooked and served her estranged husband’s parents and his aunt and uncle beef wellington at her Leongatha home in July 2023. The next day, all four guests were hospitalised with symptoms of death cap mushroom poisoning, and later, three of them died.
The accused, who had pleaded not guilty to all charges saying the deaths were accidental, will be sentenced at a later date. She faces the maximum sentence of life imprisonment for the murder charges.

The death cap is a large fungus up to around 15cm across and 15cm tall with a domed or white cap and an off-white stem.
These mushrooms can be located in parks, gardens and nature strips, the Royal Botanic Gardens Victoria has said on its website.
It often resides under exotic trees, especially oak (Quercus). There have also been reports of Amanita phalloides growing under Eucalyptus in Algeria and Tanzania, but there have been no confirmed sightings of the death cap away from exotic trees in Australia, the website added.
In Victoria, the death cap is often found widely across Melbourne in suburbs including Ashburton, Burwood, Camberwell, Canterbury, Clayton, Deepdene, East Malvern, Emerald, Heathmont, Heidelberg, Kew, Sandringham, South Yarra, Surrey Hills and Wheelers Hill.

On 29 July 2023, Erin Patterson hosted her estranged husband’s parents Don and Gail, as well as Gail’s sister Heather Wilkinson and Heather’s husband, church pastor Ian Wilkinson.
She had invited them all for lunch at her home two weeks prior. Patterson had also invited her husband, Simon, but he declined. The pair had been separated since 2015.
She served her guests beef wellington, which is a beef fillet wrapped in a mushroom paste and covered with pastry, with a side of mashed potato and green beans.
The day after the lunch, all four guests fell ill and went to hospital complaining of nausea and diarrhoea.
Within days, Don, Gail and Heather had died, while Ian Wilkinson survived after receiving an organ transplant.
