The prosecution and defence have finished their opening statements on the first day of Erin Patterson's trial. Here's what they told the court:
Erin Patterson invited her estranged husband Simon Patterson, his parents, Don and Gail Patterson, and his aunt and uncle, Ian and Heather Wilkinson, to lunch to discuss "some medical issues that she had", prosecutors said, and at lunch she told them she had cancer
All attended except her husband Simon, who pulled out the day before. Three of the guests at the lunch later died from death cap mushroom poisoning
Prosecutors alleged that Ms Patterson lied about having cancer, using it as a pretence to have the adults at lunch without Ms Patterson's children present - the defence denied this and said Ms Patterson did have cancer
Ms Patterson served individual beef wellington portions – a dish of beef, mushroom paste, and pastry – to her guests on grey plates, while she ate off a smaller, orange plate, according to guest Ian Wilkinson, who became seriously ill after the lunch, but survived
The prosecution said Ms Patterson had posted online about using a food dehydrator to cook mushrooms, and wrote she had been "hiding powdered mushrooms in everything", the prosecution said
The prosecution also said Ms Patterson's fingerprints were found on a food dehydrator she was seen on CCTV dumping after the lunch. The dehydrator tested positive for death cap mushrooms, the jury was told
The prosecution alleged Ms Patterson lied about buying the dried mushrooms from an Asian grocery store, and that mobile phone data suggests she travelled to where death cap mushrooms grew
The defence argued that "what happened was a tragedy, a terrible accident" and Ms Patterson did not intend to hurt anyone
Ms Patterson's behaviour is being portrayed as "incriminating" by the prosecution, the defence said - but she "panicked" after her guests became ill: "Might people say or do things that are not well thought out... and might make them look bad?"
The defence said Ms Patterson was "generous and kind" to her family
