Australian mother found guilty of murder over poisoned beef Wellington lunch

Australian mother found guilty of murder over poisoned beef Wellington lunch

Telegraph14 hours ago
An Australian mother has been convicted of murdering three of her estranged husband's elderly relatives by deliberately serving them a poisoned beef Wellington.
Erin Patterson, 50, laced the meal with powdered death cap mushrooms before serving it to her in-laws Don and Gail Patterson for lunch at her home in the small town of Leongatha, Victoria, in July 2023.
The mother-of-two also served the poisoned beef Wellingtons to Heather and Ian Wilkinson, the aunt and uncle of her husband, Simon Patterson.
Hours later, all four became violently ill and were admitted to hospital with acute liver damage. Gail, 70, and her younger sister Heather, 66, died on August 4 2023 – less than a week after the lunch. Don, 70, meanwhile, underwent a last-minute liver transplant but died of multiple organ failure the day after the operation.
Heather's husband, Ian, a local pastor, was the sole survivor after receiving an organ transplant and spending seven weeks in hospital. He became a critical witness in the 10-week long trial at the Supreme Court of Victoria in Morwell that has been dubbed Australia's trial of the century and gripped the nation – and the world.
On Monday, Patterson was found guilty by unanimous verdict of three counts of murder and one count of attempted murder.
Patterson, a former air traffic controller, and a true-crime fan, sat with a stoic expression as the verdict was read out in the Morwell court. She did not shed any tears. Patterson will be sentenced at a later date.
How the case unfolded
Now locked, cold and empty, Erin Patterson 's home stands at the end of a muddy track on the outskirts of town. It's a peaceful neighbourhood, nestled in the scenic foothills of the Strzelecki Range, with neat, wide houses set back from a narrow track and facing an expanse of open green fields. A place of immaculate lawns and enormous skies.
Overlooking rolling fields where beef cattle graze, a hint of a salt breeze often whips up from the Bass Strait 18 miles south.
Patterson, who only moved into the house a year before the infamous lunch, met Simon in 2002 while working as an RSPCA representative at Monash city council in Melbourne, where she was brought up by her father, a government worker, and her mother, an academic who specialised in children's literature.
Simon, who was a civil engineer working for the same council, told the court Patterson was very intelligent. She was also witty and could be funny. She held a degree in business and accounting, and had worked as an air traffic controller at Melbourne's Tullamarine Airport.
But the Pattersons' relationship was rocky. Within two years of marrying in 2007, they had temporarily separated. Patterson told the court that her son's birth in 2009 had been 'very traumatic'. She required a caesarean section after medical staff lost his heartbeat, he said.
When she and Simon split for good in 2015, they initially maintained friendly relations. She also maintained good relations with her in-laws, she claimed.
'It never changed. I was just their daughter-in-law,' she told jurors through tears during her eight days in the witness box. 'They just continued to love me.'
The dynamic between her and Simon seemed to change, however, when Simon listed himself as 'separated' on his tax return in 2022. Erin was 'upset' by this, Simon told the court. The 'chatty nature' of their relationship 'pretty much stopped', and their communication was reduced to managing the practicalities of family life.
That year, there was a disagreement over child support payments. Messages Erin sent to a Facebook group chat on December 6 2022 suggested her frustration was mounting. '[T]his family I swear to f------ God,' said one post by the user Erin ErinErin – one of three Facebook names she used. She wrote that she was 'sick of this s---' and 'f--- 'em' about Simon's parents.
Fast-forward four months and, on April 18 2023, Christine McKenzie, a retired poisons expert, posted on a site called iNaturalist that she had found deathcap mushrooms beneath an oak tree in Loch, a South Gippsland village less than 18 miles from Leongatha. On May 21 2023, fungi expert Thomas May likewise uploaded a post on the site, where users can share their nature observations, showing he too had found death caps on a street in Outtrim, 12 miles from Leongatha. He included photos and co-ordinates specifying where. (There is no suggestion either of the witnesses committed any wrongdoing.)
Did Patterson use the citizen science website to source the deadly mushrooms that ended up in the fatal lunch? The prosecution suggested so, alleging that phone data indicated that she had travelled to Loch on April 28, and to both Loch and Outtrim on May 22.
Patterson told a different story, initially at least. She had bought sliced button mushrooms from a Woolworths store in Leongatha and dried mushrooms from a Chinese grocer in the Oakleigh or Glen Waverley area (both suburbs of Melbourne), she told medical staff after the poisonings. She denied having ever seen the posts on iNaturalist.
Patterson admitted in court that she had gone foraging for mushrooms in the months preceding the lunch (despite telling police, at first, that she hadn't), but said she never deliberately sought out the lethal death caps.
And, although she didn't deny they were in the meal she served, she said this was unintentional and afterwards, she 'panicked'.
She had long been a mushroom lover, she told the court. Her interest in wild varieties had started in 2020, when she noticed them while walking around the nearby town of Korumburra during lockdown, she said.
Three months before the deadly lunch, she had bought an electronic dehydrator and shared photos of her dehydrating mushrooms to a Facebook group chat. After her victims had fallen ill, two samples taken from the dehydrator tested positive for deathcap mushrooms.
But when her guests turned up on that fateful summer day just under two years ago, they had no cause for suspicion. It was 'very rare' for Patterson to host social gatherings at home, Simon told the court; but she ostensibly had a good reason on this occasion. She had some 'important medical news' to discuss, or so she claimed.
When Simon pulled out at short notice, she told him it was 'really disappointing' as she had 'spent many hours this week preparing lunch'. It was important, she stressed, that everyone was there and that she could have the necessary conversations.
The lunch went ahead all the same. To make the beef Wellingtons, Patterson adapted a recipe from the food blog RecipeTin Eats, serving mashed potato and green beans on the side. She told the court she had added to the main dish what she believed were dried fungi purchased from an Asian supermarket and stored in a container in her pantry. But, she acknowledged, 'Now I think that there was a possibility that there were foraged ones in there as well.'
Her son, 14, and daughter, nine, were not present at the lunch, but the reason for this seemed clear when Erin delivered her news: that she was suffering from 'life-threatening' ovarian cancer.
It later transpired that she had never received any such diagnosis. What she had done, she said in court, was consult 'Dr Google' because she was worried about her health. She meanwhile planned to have weight-loss surgery but was too embarrassed to admit this, she said, and so intended to pretend to her in-laws that she would instead be having cancer treatment.
'I was ashamed of the fact that I didn't have control over my body or what I ate,' she said. 'I didn't want to tell anybody, but I shouldn't have lied to them.'
Her guests weren't to know she was lying, of course, and prayed for her that day. (Patterson said she was a 'fundamental atheist' but that Simon was a Christian who had converted her.) They also advised their hostess on how to break the news of her supposed illness to her children.
That night, the true nature of the meal became horrifyingly clear. The Wilkinsons were admitted to Leongatha Hospital with severe gastric symptoms. Don and Gail Patterson, similarly afflicted, also went to hospital on July 30. All received intensive treatment, but Erin Patterson's parents-in-law and Mrs Wilkinson died within days, of 'altered liver function and multiple organ failure'. Mr Wilkinson was placed in a coma, remained in hospital for almost two months and survived.
Erin Patterson, too, went to hospital with stomach symptoms. By this point, her four guests had been diagnosed with death cap mushroom poisoning while Erin, for her part, 'didn't look unwell', a nurse told the court. Instead she was angry and tearful, repeatedly insisting, 'I don't want any of this,' in relation to her hospital treatment. She was discharged on August 1.
Was she faking illness? The defence case was that no, she was genuinely unwell, since she too had eaten the meal. She simply wasn't as unwell as her guests. Erin also explained her very different reaction to the meal by claiming she made herself vomit not long after her guests had left, and after bingeing on most of a cake. It was a problem she had battled for decades, she said.
She told the court she had fed her children leftovers of the beef Wellington the day after her guests had come over, but had scraped off the mushrooms and pastry because they were fussy. The prosecution cast doubt over her account.
Erin Patterson had eaten off a different-coloured plate from those her guests had eaten off, the court heard. Mrs Wilkinson thought this odd, telling Simon while she was in hospital: 'Her plate had colours on it. I wondered why that was. I've puzzled about it since the lunch.'
Mr Wilkinson confirmed in his evidence that Patterson had served her guests' food on four large grey plates while she herself had eaten from an orange/tan-coloured one.
The prosecution also suggested that Patterson had lied about feeding her children beef Wellington leftovers, and questioned why she would give a meal to her children when she 'knew or suspected' that it had made her guests ill.
'I didn't know or suspect that,' she replied.
She didn't think, at first, that they needed to be brought to hospital either, since she didn't think they had eaten any of the mushrooms, she explained.
'I suggest that you would have wanted them to have immediate medical attention, notwithstanding your claim that they hadn't eaten the mushrooms,' prosecutor Nanette Rogers said.
Four days after the lunch, on August 2, Patterson jettisoned the dehydrator at a tip just outside town. She later claimed she had panicked after her guests had fallen ill. She also wiped her phone in the days after the lunch, which she said was due to her fear that she would be blamed for her guests' deaths as Simon had accused her of poisoning them.
When news of the poisonings broke and began to attract media attention, Patterson tearfully insisted she was 'devastated to think that these mushrooms may have contributed to the illness suffered by my loved ones'.
She had, she said, 'no reason to hurt these people, whom I loved'.
Reason or not, on November 2 that year, she was formally charged by police.
By the time her sensational trial opened at the end of April this year, the reason remained elusive, and the prosecution offered no possible motive to the jury.
'You might be wondering, now, 'Why would the accused do this, what is the motive?'' she said. 'You might still be wondering this at the end of the trial.'
Indeed they might, along with the many others who have followed the ins and outs of these strange and shocking proceedings.
It was an oddity – and potentially a weakness in the case – that Patterson's barrister attempted to use to bolster the defence. In his closing address to the court, senior counsel Colin Mandy said the prosecution had relied on 'ridiculous' and 'convoluted' propositions, including the idea that it didn't matter that Erin had no motive, and that she thought it 'would all be passed off as some strange case of gastro, where everyone died except her'.
But, said Rogers in her own closing address, there was 'no reasonable alternative explanation' for the deaths other than Patterson seeking out death caps and adding them to the meal she served 'with an intention to kill'.
Justice Christopher Beale, in his summing up, pointed out to the jury 'inconsistencies' in evidence given by some of the trial witnesses, but also in evidence given by Ms Patterson. How much she ate of her beef Wellington, whether she had a habit of picking and eating wild mushrooms, the source of the the mushrooms used in the meal – apparent question marks hung over these and other matters.
In convicting the triple murderer, jurors evidently agreed. A trial that transfixed the world is over. Justice done for the four innocent victims. Yet the question of why Patterson killed will undoubtedly prove a puzzle for years to come.
Residents in this normally quiet corner of Gippsland are now bracing themselves: they know another wave of intense media attention in the form of news crews messing up their grass verges is on the way.
When The Telegraph visited the area, Justice Christopher Beale was coming to the conclusion of his jury directions at LaTrobe Valley Magistrates' Court, in Morwell, 35 miles north-east of Leongatha.
'It's been very tense during the trial, everyone is on tenterhooks,' said local resident Steven Lodge.
Lodge, 52, an IT specialist for a local water company, lives in a single-level property just a few houses away from Patterson, and would often see her when he was out walking his two dogs daily. 'I'd only lived here for a short time before it happened, but I remember she would wave and give me a nod; she just seemed like a friendly, normal mum,' he said.
'She'd be in the car with her two kids ferrying them around at all times, just like a lot of parents with busy lives.'
Like many locals, Lodge is quite the expert on the trial and what's been reported in the media.
'I've been following the trial closely and it still seems surreal the lunch happened here on this street.'
Many people wanted to believe Patterson's testimony that the whole incident was an accident, he says.
'This is a small community where people help each other out and care for each other; intentionally poisoning people has never been heard of… but then… there are so just so many odd things that are hard to explain, like switching sim cards on the phones after it happened and dumping the dehydrator at our local tip.
'At the same time, if you think you are going to be wrongly blamed for something you didn't do and people are dying, maybe anyone would panic.'
On the metal gates at the top of Patterson's 60ft driveway, there is a laminated note to media written on her behalf. Independently wealthy, Erin funded and helped design this property herself, only a few years ago. The note is sharp and to the point.
'Please be advised that the owner of this property hereby gives notice to all members of the media or any person employed or contracted to an organisation, that you are not permitted to enter any part of this property as marked by the boundary fence. If you do enter then you are committing the offence of trespass and will be reported to the police.'
In the small hamlet of Loch, shop keepers and locals are bemused to find themselves wrapped up in this sprawling, complicated story. It's a tiny historical pit-stop, off the main road, popular with Melburnians heading to coastal holiday homes and campsites.
There is an antiques shop, a pretty red-brick brewery and distillery which once used to be an old bank, a general food store and a couple of wine bars which serve expensive menus to match the expensive car brands that park up at the weekends and in holiday season.
It is here that Patterson foraged for death cap mushrooms under oak trees, after a photo was posted on a nature website in April 2023, a few months before the deadly lunch. Police allege her mobile phone pinged from a nearby tower.
One shopkeeper, who did not want to be named, sighs. 'It's been very hard to read for a lot of us.'
With the trial over, 'Everyone can then focus on what matters – that we've lost three locals who, by all accounts, were very much loved.'
In Korumburra Baptist Church, where survivor Ian Wilkinson still takes the weekly Sunday service at 10.30am, a different message awaits visiting media or curious passersby.
' Matthew 7:15 – Be on your guard against false prophets; they come to you looking like sheep from the inside but on the outside they are really like wild wolves. '

Notting Hill Carnival fugitive found guilty of bus driver's stab murder

A fugitive has been found guilty of murdering his ex-girlfriend's father after being caught at Notting Hill Carnival. Kamar Williams, 34, stabbed Derek Thomas, 55, in Hackney, north-east London, last July 30. After the 'frenzied' attack, Williams, from the Isle of Dogs, east London, went on the run. He was finally detained after crashing a hired BMW and fleeing on foot, with police in pursuit. On Monday, a jury at the Old Bailey found Williams unanimously guilty of murder and guilty of having a bladed article by a majority of 11 to one. There were cries of 'yes' from the public gallery as the jury delivered the verdicts after deliberating for 17 hours and 48 minutes. Judge Angela Rafferty KC adjourned sentencing until Friday July 18 and remanded Williams into custody. Anthony Orchard KC had told jurors the defendant had been looking for the victim's daughter Carron Thomas on the night of the murder. Earlier that evening, she had received threatening and abusive text messages from the defendant, the court was told. The jury heard that Ms Thomas had called police twice in the hours before her father was attacked. Just before 7pm, she reported to police that Williams was at her sister's address, but when police arrived he was not there. Just after 10.30pm, she called police again, while she was at her sister's house, believing she could see Williams walking through the estate. Williams went to Mr Thomas's home looking for him or his daughter, but they were not in. As he was driving away, he spotted Mr Thomas walking home on Stoke Newington Common at around 11pm. Mr Thomas had finished a late shift as a bus driver and had gone into Tesco for some food before heading home. Williams stopped the van he was driving in the middle of the road, got out and stabbed Mr Thomas five times. The contents of Mr Thomas's shopping bag were strewn over the pavement and road. Mr Orchard said: 'Mr Thomas may well have swung a punch at the defendant but if he did, you can be sure he was acting in a desperate attempt to defend himself. 'There can be no doubt that the attacker was this knife-wielding defendant. 'Mr Thomas was struck by the knife on five occasions in different places in what was, you may think, a frenzied attack. 'If you were walking home across the common minding your own business and someone ran at you with a large knife you would have been terrified – clearly so was Mr Thomas. 'Having stabbed Mr Thomas, the defendant left him for dead and went on the run, only being arrested a month later at the carnival.' Giving evidence, Williams claimed he acted in self-defence after the victim produced a knife. He claimed he had been looking to talk to the bus driver about his relationship with his daughter. He told jurors he took the knife from Mr Thomas and stabbed him with it. Following the guilty verdicts, Detective Inspector John Marriott, of Scotland Yard, said: 'This was a brutal and premeditated attack on a much-loved father. 'Kamar Williams showed clear intent that night, driving to Derek's home, waiting for the right moment, and carrying out this senseless act of violence. 'The swift response from our officers, combined with extensive CCTV, forensic work, and determination from our investigation team, led to his arrest and conviction. 'Our thoughts remain with Derek's family, who have shown immense strength throughout this ordeal.' Mr Thomas's family said in a statement: 'Derek will be greatly missed by his family and friends, he was a dedicated family man and worked hard to provide for them. He was the life and soul of the family. 'Derek was always on hand to provide support, knowledge, advice and was a calming influence when it was required. His passing has left a massive hole in the lives of his wife, children, grandchildren, family and all that knew him. He was greatly loved by all and will never be forgotten.'

Teen who murdered man in front of shoppers and children is jailed

A teenager who stabbed a man to death on a sunny afternoon in front of shoppers and children using a knife he had bought for self-protection has been jailed for 13 years. Passing sentence, Mr Justice Paul McDermott said the teen, who can't be named because he was a minor when he first came before the courts, murdered Aaron Keating (43) as an "angry aggressive youth acting in a drug rage". Advertisement Although he has pleaded guilty to murder, the youth is not subject to a mandatory life sentence due to his age at the time of the offence. Mr Justice McDermott said he had to take into account the defendant's age, lack of maturity and the need to rehabilitate young offenders. Therefore he sentenced the defendant to 15 years with the final two years suspended for two years on a number of conditions. The now 19-year-old was one month short of his 18th birthday when he murdered Mr Keating on June 13th, 2023 at Main Street, Ongar, Dublin 15. Mr Justice McDermott said it had been a sunny Tuesday afternoon when the defendant and a group of youths were hanging around Main St smoking cannabis. Mr Keating, who had mental health difficulties all his life, was a frequent visitor to the area and was known to all the youths. Advertisement CCTV footage CCTV footage showed an altercation between Mr Keating and the defendant which prompted the youth to run to a nearby stairwell where he had stashed a knife for self-protection. He returned within 90 seconds of the first altercation and pursued Mr Keating across the road despite one of his friends telling him to stop. The defendant attempted to stab Mr Keating but missed before he "made another lunge", the judge said, causing the fatal wound to the abdomen. A pathologist found the cause of death to be haemorrhage and shock due to the single stab wound. Mr Justice McDermott noted that the defendant attacked his victim openly, in a public place, presenting a "terrifying spectacle" to shoppers, including women and children. Advertisement The defendant fled the scene, disposed of the knife and made no attempt to assist the dying man, the judge said. Mr Keating was loved by his family, the judge said, and is deeply missed. His life was "needlessly and violently taken", he said. The judge said that the defendant had done well in primary school but by the age of 12, he began regularly using drugs. He had seen numerous doctors and therapists over the years but continued to abuse drugs. He said drug use had "a dominating role" in the murder and in causing a disintegration in the youth's education. Drug rehabilitation, he said, will be a factor in efforts to prevent the teenager reoffending. The defendant is currently considered at a high risk of reoffending if he were returned to a community setting within 12 months. Mr Justice McDermott set a headline sentence of 25 years but reduced that to 21 to account for the defendant's age. He further reduced the sentence to 15 years after considering mitigating factors including the teenager's guilty plea and his "early and consistent expression of remorse, which appears to be genuine and comprehensive". Advertisement When sentencing children, the Supreme Court has found that it is preferable to suspend part of the sentence to encourage rehabilitation. Mr Justice McDermott suspended the final two years on condition that the defendant keep the peace for two years after release, address his addiction needs with the probation services and accept any treatment recommended. He must also participate in a drug rehabilitation programme and any mental health services recommended by the probation services. Sentencing At a sentencing hearing last week, Det Gda Jenny Greene told prosecution senior counsel James Dwyer that the defendant was hanging around Ongar smoking cannabis with a group of teenagers from about 3pm that afternoon. He had a number of interactions with Mr Keating. At about 6pm, "something triggered a reaction" in Mr Keating, who pushed the youth up against a window. Advertisement The other youths who had been with the defendant encouraged Mr Keating to leave the area. He crossed the street but about 90 seconds after the previous interaction, the defendant appeared wearing his t-shirt over his head and face and carrying a knife. He ran towards Mr Keating and made "a number of attempts to stab him", inflicting one stab wound to the abdomen, Det Gda Greene said. Mr Keating collapsed within seconds and died from the injury. The defendant went to a garda station the following morning with his mother and admitted to what he had done. In subsequent interviews, he said he had been smoking cannabis and taking mushrooms when Mr Keating asked him for a joint. He said he laughed, refused to give him a joint and called Mr Keating a junkie. Ireland Pensioner blackmailed woman with sex pics recovere... Read More He claimed the deceased attacked him so he ran to get the knife so he could "get him before he gets me". He said he didn't want Mr Keating to die but wanted to scare him. "He was egging me on," he said. "I don't know what he said but he triggered me." The defendant entered his plea of guilty to murder following a Supreme Court ruling last year that, despite now reaching adulthood, he will not face a mandatory life sentence because he was a child when he committed the offence. The teen previously sought to halt the proceedings against him because, having aged out while awaiting trial, he faced a mandatory life sentence if convicted of murder. However, following a recent Supreme Court ruling, judges now have discretion when sentencing a person who committed murder while a child, regardless of what age they are when they come before the courts.

Brantham murder accused is 'oddball' but no killer, defence says

A man accused of murdering a mother-of-six while she was walking her dog is an "oddball" but not a killer, according to his defence Barclay, 56, of no fixed address, is charged with the murder of Anita Rose, 57, who was attacked on 24 July 2024 in Brantham, Suffolk before dying four days Barclay, who denies killing the grandmother, has chosen not to offer any evidence or to be cross-examined during the course of the trial at Ipswich Crown his closing speech, Simon Spence KC, who is representing Mr Barclay, told the jury they "can't find him guilty" unless they are certain he was the killer. "There is no evidence at all of any contact between Roy Barclay and Anita Rose's body… contact there must have been if he was the killer," he said."He's innocent unless or until you, the jury, say otherwise." Ms Rose had been walking her dog Bruce along fields next to the railway line, sewage works and Stour estuary in Brantham early in the morning when she was grandmother of 13, who was found unconscious and with serious injuries, was taken to Addenbrooke's Hospital, in Cambridge, where she later prosecution said Mr Barclay murdered Ms Rose by stamping on her multiple times while wearing walking boots before fleeing the is claimed he took Ms Rose's pink jacket, mobile phone and a key as "trophies of the killing".But his defence barrister, Mr Spence, argued the defendant, who was homeless, may have found the possessions while "scavenging"."If he was the killer obviously the thing to do is to get rid of them," he said."Would you keep those items or would you dispose of them as quickly as you could?"And if he was the killer, [why did he keep his boots]? Why not just get rid of them? Chuck them in the river?" He was also caught on CCTV in Brantham at the time of the assault but Mr Spence said that "being in the vicinity of a crime means nothing"."When you stand back objectively at the CCTV which puts Barclay on the 24 July in the Brantham area, what does it prove? We submit - nothing at all," he added."Is this of real significance, that he was in Brantham? It's one of the places he kept his clothing and possessions, a frequent visitor. [So], I suggest not." Mr Spence said the absence of DNA weakened the prosecution's case and he was keen to stress to the jury that there was no sexual also told the jury Mr Barclay was autistic, was unable to communicate verbally, and that his silence did not prove any guilt."Each strand there is doubt, it creates cumulative doubt, which you can't overlook," Mr Spence told the trial continues.
