Erin Patterson is accused of tampering with the food after she was reportedly given a job in the prison kitchen while on remand and waiting to stand trial for murder
A woman convicted of murdering three relatives by poisoning them with deadly mushrooms is now accused of targeting a fellow inmate with another poisoned meal.
Erin Patterson is accused of tampering with the food after she was reportedly given a job in the prison kitchen while on remand and waiting to stand trial. Today, she was found guilty of lacing a beef wellington with poisonous mushrooms and feeding to her estranged husband’s parents and aunt after inviting them to lunch.
Her former parents-in-law, Don and Gail Patterson, both 70, and Gail Patterson’s sister, Heather Wilkinson, 66, died after the lunch at Patterson’s home in the town of Leongatha, Australia, the court heard.
She was found guilty of their murders and the attempted murder of Mrs Wilkinson’s husband Reverend Ian Wilkinson, who ate the food but survived.
Patterson, a mother of two, was convicted at the Supreme Court trial in Victoria state after the jury returned a verdict after six days of deliberations, following a nine-week trial.
Following her conviction, The Herald Sun reports that following a dispute with Patterson, a fellow prisoner became sick – and pointed the finger at the triple murderer.
A Corrections Victoria source confirmed to Daily Mail Australia that Patterson had been given a job in the prison kitchen despite the nature of the allegations against her.
A Department of Justice and Community Safety Victoria spokesman denied this however. They added: “There is no evidence to support that there has been any contaminated food or suspected poisonings at Dame Phyllis Frost Centre.”
During her trial the court heard that all of Pattison’s guests fell ill following the lunch, which consisted of beef wellington, mashed potatoes and green beans the court was told.
Prosecutors had alleged that she laced the meal with deadly death cap mushrooms, also known as Amanita phalloides.
Mrs Wilkinson and Mrs Patterson died on Friday 4 August 2023, while Mr Patterson died a day later and Reverend Wilkinson spent seven weeks in hospital but survived.
Her estranged husband Simon Patterson was also invited to the lunch and initially accepted but later declined, the trial was told.
The court heard how all four guests fell ill after eating their meal off four large grey dinner plates, while Patterson ate hers off a smaller, tan coloured plate.
The prosecutions case alleged that she ate of a visibly different plate in order to ensure that there was no cross contamination.
Reverend Wilkinson said that straight after the meal, Patterson told the group that she had been diagnosed with cancer, suggesting that she was wanting their advice on the best way to tell her children.
The defence did not dispute his claims.
It wasn’t disputed that Patterson served the mushrooms or that the food killed her guests.
The jury was only required to decide whether she knew the lunch contained the poisonous mushrooms, and if she intended for them to die.
Prosecutors didn’t offer a motive for the killings, but during the trial highlighted strained relations between Patterson and her estranged husband, and frustration that she had felt about his parents in the past.
Patterson will be sentenced at a later date.
