SYDNEY: An Australian woman accused of killing three lunch guests with toxic mushrooms fell sick from the same meal, her defense said Thursday, rejecting claims she faked her symptoms.

Erin Patterson, 50, is charged with murdering her estranged husband鈥檚 parents and aunt in July 2023 by spiking their beef Wellington lunch with death cap mushrooms.

She is also accused of attempting to murder a fourth guest 鈥� her husband鈥檚 uncle 鈥� who survived the lunch after a long stay in hospital.

Patterson has steadfastly maintained her innocence during a seven-week-long trial that has made headlines from New York to New Delhi.

As the trial came to its closing stages, defense lawyer Colin Mandy poked holes in the prosecutor鈥檚 case, saying his client, too, fell ill after consuming the beef-and-pastry dish.

Patterson鈥檚 medical tests at the hospital revealed symptoms 鈥渢hat can鈥檛 be faked,鈥� including low potassium and elevated hemoglobin, he said.

鈥淪he was not as sick as the other lunch guests, nor did she represent she was,鈥� Mandy said.

The prosecution maintains Patterson did not consume the fatal fungi and faked her symptoms.

Mandy said his client lied in panic in the days after the lunch, trying to 鈥渃onceal the fact that foraged mushrooms went into the meal.鈥�

鈥淚f that was found out, she feared she would be held responsible,鈥� her defense said.

鈥淪he panicked when confronted with the terrible possibility, the terrible realization, that her actions had caused the illness of people she liked.鈥�

Mandy said he was not 鈥渕aking an excuse鈥� for Patterson鈥檚 behavior after the lunch, but that it did not mean she meant to harm or kill her guests.

Patterson originally invited her estranged husband Simon to join the family lunch at her secluded home in the farming village of Leongatha in Victoria state.

But he turned down the invitation on the eve of the meal, saying he felt uncomfortable going, the court heard earlier.

The pair were long estranged but still legally married.

Simon Patterson鈥檚 parents Don and Gail, and his aunt Heather Wilkinson, attended the lunch.

All three were dead within days. Heather Wilkinson鈥檚 husband Ian fell gravely ill but eventually recovered.

The trial in Morwell, southeast of Melbourne, is in its final stages.
