Within the days earlier than the jury members entered sequestered deliberations, Justice Christopher Beale warned that Patterson’s lies didn’t inherently show her guilt.

The jury agreed.

A recap of the case 

Patterson has been married to her husband, Simon, since 2007, however the two separated completely in 2015 after a number of splits and reconciliations. In testimony, the couple — who share custody of their two youngsters — spoke about having an amicable relationship that deteriorated within the winter of 2022 over points associated to little one assist funds.

Then, in July 2023, Patterson invited Simon and several other of his kin over for lunch: his dad and mom, Gail and Donald Patterson, each 70, in addition to Gail’s sister, Heather Wilkinson, 66, and Heather’s husband Ian Wilkinson, 68 — the only survivor.

Patterson informed the group that she wished to debate a medical concern she was having and whether or not to inform her youngsters, who weren’t current through the meal. After Simon pulled out the night time earlier than, she expressed her disappointment in a textual content, writing: “I wanted it to be a special meal, as I may not be able to host a lunch like this again for some time.”

Wilkinson later testified that Patterson informed the company at lunch that she had been recognized with most cancers.

The prosecution mentioned medical information confirmed no such analysis, and accused Patterson of mendacity as a pretense for the adults-only meal. Patterson admitted from the stand that “I didn’t have a legitimate medical reason,” and mentioned she was too embarrassed to inform her company she was really contemplating weight-loss surgical procedure.

By that time, the household had completed their meal. Patterson had made every of the company their very own particular person beef Wellington pastry, and served herself on a plate that was a distinct measurement and coloration than the opposite 4. That quirk was noticed not solely by Wilkinson however his late spouse, Heather, who talked about it to Simon Patterson when he took her to the hospital the next day.

The 2 {couples} began to really feel sick that night time, experiencing dozens of episodes of vomiting and diarrhea even after being hospitalized the subsequent morning. They have been initially in a position to share their experiences and medical histories with docs, who grew more and more involved that they weren’t experiencing simply gastroenteritis.

Toxicologists decided that their signs have been indicative of “serious toxin syndrome caused by ingestion of amanita phalloides mushrooms,” also referred to as dying cap mushrooms.

The sufferers weren’t instantly given the antidote as a result of there wasn’t sufficient proof to substantiate that they had ingested such mushrooms. Regardless of receiving different types of therapy — together with an emergency liver transplant, in a single case — their situations continued to deteriorate.

Heather Wilkinson and Gail Patterson died on Aug. 4, and Donald Patterson died the next day. Ian Wilkinson was extubated on Aug. 14 and discharged to rehabilitation on Sept. 11.

Through the trial, a lot time and scrutiny was given to Erin Patterson’s conduct after her company fell sick and died.

For example, there was a lot forwards and backwards over whether or not Patterson ever bought sick herself. Patterson mentioned she skilled diarrhea for a number of days beginning inside hours of the lunch, although her precise accounts diversified.

Prosecutors, citing medical information and docs’ testimonies, argued she wasn’t experiencing any signs of mushroom poisoning and persistently resisted hospital care. Patterson’s attorneys alleged that she merely did not eat sufficient of the dish to get as sick because the others. By the use of clarification, Patterson testified that she threw up later that day after consuming the remainder of the cake that one in every of her company had introduced.

Patterson additionally acknowledged she didn’t inform authorities about the potential of dying cap mushrooms being within the dish whilst her company lay within the hospital, as an alternative telling them that she had used a mixture of mushrooms: recent from an area chain and dried from an unspecified Asian grocery retailer.

When police requested her whether or not she had ever foraged for mushrooms, she mentioned no — which she and her protection attorneys additionally acknowledged was a lie. She additionally lied about having a meals dehydrator, which she had bought months earlier than the lunch and shortly disposed of after the deaths.

On the stand, Patterson mentioned she had dumped the dehydrator out of panic because the tragic implications of her meal grew to become clear, calling it “this stupid, knee-jerk reaction to just dig deeper and keep lying.” Her staff maintained that she had a very good relationship together with her in-laws, and no purpose to harm them.

Simon Patterson was the prosecution’s first witness within the trial, and was questioned extensively about their relationship. Erin Patterson later testified — and Simon denied — that in a dialog together with her husband within the hospital following the lunch, the subject of her dehydrator got here up and he requested: “Is that how you poisoned my parents?

Prosecutors also accused Patterson of trying to cover her tracks in other ways, such as doing a factory reset of her phone during the police investigation. They later found photos in her camera of wild mushrooms being weighed on the dehydrator tray in her kitchen.

Patterson testified that she cleared the phone because “I knew that there have been pictures in there of mushrooms and the dehydrator and I simply panicked and did not need [detectives] to see them.”

What prosecutors alleged

Prosecutor Nanette Rogers devoted her closing arguments to what she referred to as Patterson’s 4 “calculated deceptions” on the coronary heart of the case.

These have been, based on Rogers: the fabricated most cancers declare Patterson used as a pretense for the lunch invitation, the deadly doses of poison she put within the beef Wellingtons, her makes an attempt to make it appear that she additionally suffered dying cap mushroom poisoning and the “sustained cover-up she embarked upon to conceal the truth.”

She mentioned Patterson intentionally planted the seed by mentioning a lump on her elbow to one of many company weeks upfront, and did not take into consideration tips on how to account for the most cancers lie as a result of “she did not think her lunch guests would live to reveal it.”

Citing cellphone pictures and placement information, Rogers alleged that Patterson intentionally positioned — utilizing a naturalist web site — and picked dying cap mushrooms rising in a close-by city, dehydrated them right into a powder and hid them in her company’ dishes.

“She had complete control over the ingredients that went into the lunch and she took steps to make sure she did not accidentally, herself, consume death cap mushroom whilst ensuring that her guests did,” Rogers mentioned.

She mentioned that after the lunch, Patterson pretended she was additionally sick from the lunch as a result of “her good health … would give her away about what she’d done.”

She accused Patterson of not with the ability to hold her story straight, giving various accounts of the timing and severity of her signs to completely different individuals and leaving the hospital in opposition to medical recommendation. Whereas Patterson’s attorneys mentioned she did so to get her youngsters’ issues so as, the prosecution recommended she was panicking and making an attempt to cowl up her tracks.

And, Rogers mentioned, Patterson’s well being information present she did not have the identical signs as the opposite company. For instance, by the point Patterson mentioned she had recovered a couple of days out from the lunch, “all four of the lunch guests were in induced comas.”

After their deaths, Rogers alleged Patterson lied and deceived individuals in a number of methods, together with by deceptive investigators concerning the supply of the mushrooms, which sparked a frantic, finally unsuccessful Division of Public Well being seek for dying cap mushrooms on native grocery cabinets (there have been no different experiences of sickness within the space). She mentioned Patterson modified her story after the dehydrator was found at an area waste facility.

Rogers did not accuse Patterson of getting a particular motive, but in addition mentioned that wasn’t required for a responsible verdict.

“You don’t have to know why a person does something in order to know they did it,” she mentioned.

What Patterson’s attorneys maintained

Patterson’s lawyer, Colin Mandy, accused prosecutors of ignoring some items of proof and cherry-picking others to assist their assertion of her guilt.

Mandy mentioned not solely did Patterson not have a motive to hurt her husband’s household, she had years’ price of “anti-motive:” She had a very good relationship with Simon’s dad and mom — her personal youngsters’ grandparents — and was in a very good place financially and emotionally on the time of their deaths.

And he argued that even when Patterson actually had meant to poison them, she would by no means have achieved among the issues she did alongside the best way, like purchase the dehydrator in her personal identify, take pictures of mushrooms in a dehydrator, after which “wait for so long after the meal” to dump the dehydrator, which she did utilizing her personal automobile, based on surveillance footage.

“[She] doesn’t attempt to disguise those actions in any way,” he mentioned. “It could only have been panic. Not because she was guilty, but because that’s what people might think.”

Mandy mentioned the most cancers lie could not have been a ruse to get the group to lunch, as a result of she did not inform them about it till after they’d eaten the meal. He additionally disputed the accounts of the different-colored plate, saying she would have hypothetically wanted to mark the untainted pastry itself with a purpose to differentiate it from the others on the tray within the oven.

And he careworn that human reminiscence is imperfect. Whereas Patterson might have answered completely different peoples’ questions in numerous methods, Mandy mentioned, there was “very little meaningful variation in the accounts that she gave.” Mandy acknowledged that a few of these accounts have been lies, however mentioned Patterson was “not on trial for lying.”

“This is not a court of … moral judgment,” he mentioned. “You shouldn’t take the leap from this lie about a lump on her elbow to finding her guilty of triple murder. Those two things are a very, very long way apart.”
