MORWELL, AUSTRALIA — A jury has retired to decide the fate of Erin Patterson, 50, an Australian woman accused of cooking a deadly mushroom lunch for relatives.
Patterson pleaded not guilty to four charges, including three counts of murder and one count of attempted murder, related to a beef Wellington meal served at her home in July 2023. Three people died and one became seriously ill after eating the dish.
According to BBC News, Sydney, the prosecution claims Patterson knowingly put toxic death cap mushrooms into the home-cooked meal. Prosecutors argued she later lied to police and disposed of evidence. The defense, however, claims Patterson accidentally used the poisonous fungi in the dish. Her lawyers argued she lied because she panicked after harming people she loved.
Patterson’s in-laws, Don Patterson and Gail Patterson, both 70, along with Gail’s sister Heather Wilkinson, 66, all fell ill. They died days after lunch at Patterson’s home. Heather’s husband, local pastor Ian Wilkinson, recovered after weeks in an induced coma. Simon Patterson, the accused’s estranged husband, had also been invited to the lunch but did not attend.
On Monday, June 30, Judge Christopher Beale gave his final instructions to the 14-member jury. He summarized evidence from the prosecution and Patterson, the sole defense witness. After nearly 2 months and testimony from more than 50 witnesses, the final 12 jurors were selected by ballot before beginning deliberations.
In her closing arguments, prosecutor Nanette Rogers SC told the court Patterson has “told so many lies it’s hard to keep track of them.” The prosecution alleged Patterson lied to her relatives about a cancer diagnosis to convince them to attend the fatal lunch. They also claimed she poisoned them and then faked an illness to cover her actions.
Prosecutors argued Patterson’s lies to police and medical staff about foraging for wild mushrooms, and discarding a food dehydrator, showed her guilt. “She has told lies upon lies because she knew the truth would implicate her,” Nanette Rogers said. “When she knew her lies had been uncovered, she came up with a carefully constructed narrative to fit with the evidence – almost.”
Rogers told the court there was no “particular motive” for the alleged crime. However, she said the jury should still have “no difficulty” in rejecting the argument that “this was all a horrible foraging accident.”
The defense argued the lack of motive was a key point. Patterson had no reason to kill her guests, they stated. As reported by AP News, Patterson told the jury she was close to her in-laws and never intended to harm them.
Patterson claimed she added dried mushrooms from a pantry container while preparing lunch. She believes this container held store-bought and foraged mushrooms. She also told the court she had bulimia, an eating disorder, for years. Patterson claimed she forced herself to vomit after the beef Wellington meal. Her defense team stated this explains why she did not get as sick as the others who ate it.
Patterson said the lie about having cancer was because she was embarrassed about plans to get weight-loss surgery. She stated she lied about her mushroom foraging hobby because she feared authorities would blame her for making her relatives sick.
“She’s not on trial for lying,” defense lawyer Colin Mandy SC said. “This is not a court of moral judgment.” He accused the prosecution of trying to force “puzzle pieces” of evidence together, “stretching interpretations, ignoring alternative explanations because they don’t align perfectly with the narrative.”
In his final instructions, Judge Beale told the jury members they alone are the “judges of the facts in this case.” He said they shouldn’t convict Patterson for lying, as there are “all sorts of reasons why a person might behave in a way that makes the person look guilty.” He added that while “any reasonable person would feel great sympathy” for the Patterson and Wilkinson families, jurors must not be swayed by emotions.
The jury has now been sequestered. This means they will stay in supervised accommodation with little to no contact with the outside world until they reach a decision.
At the end of the day on Thursday, the jury still had not reached a verdict after the fourth day of deliberations.
Presumption of Innocence: A presumption of innocence means that any defendant in a criminal trial is presumed to be innocent until they have been proven guilty beyond a reasonable doubt in a court of law. The defendant in this case is only accused of the charges set forth in the criminal complaint. They are innocent until proven guilty.
