Erin Patterson mushroom murder trial LIVE updates: Verdict could come as early as today as judge gives jury firm warning

Justice Christopher Beale commenced his address to the jury – or ‘charge’ – last week after allowing jurors to prepare for the closing stage of the marathon Erin Patterson murder trial.

On Thursday, Justice Beale indicated that his address will conclude today and then two jurors will be balloted out before the remaining 12 decide Patterson’s fate.

This means there is a possibility a verdict in the murder trial, which has garnered worldwide attention, could come as early as today.

Patterson, 50, is accused of murdering her in-laws, Don and Gail Patterson, and Gail’s sister, Heather Wilkinson, after allegedly serving them a beef Wellington lunch made with death cap mushrooms.

Patterson is also accused of attempting to murder Heather’s husband, pastor Ian Wilkinson, who survived the lunch after spending several weeks in an intensive care unit.

The court heard Patterson’s estranged husband, Simon (pictured), was also invited to the gathering at her home in Leongatha, in Victoria’s Gippsland region, but didn’t attend.

Witnesses told the jury that Patterson ate her serving from a smaller, differently-coloured plate to those of her guests, who ate off four grey plates.

Patterson told authorities she bought dried mushrooms from an unnamed Asian store in the Monash area of Melbourne, but health inspectors could find no evidence of this.

Justice Beale took the jury through miscellaneous concerns with the evidence, including medical evidence from Leongatha hospital related to PCR tests.

The jury heard Patterson’s bowel movements had PCR tests performed on them, but no toxins were detected in the samples.

However, Justice Beale said PCR tests would not have picked them up anyway and told the jury to ignore it.

Justice Beale then told the jury he had 100 or so more pages of his charge to go, before sending them out for a short break.

Pastor Ian Wilkinson, with his arms crossed, looked sombre as the jury was instructed on how it should deal with the charge related to his attempted murder.

‘Turning to the elements of attempted murder, as you know… to prove that the accused committed the offence of attempted murder, in relation to Ian Wilkinson, the prosecution must prove the following four elements beyond reasonable doubt,’ Justice Beale said.

‘One, that the accused consciously, voluntarily and deliberately served Ian Wilkinson a poisoned meal, that’s the alleged conduct.

‘Two, the accused alleged conduct was more than merely preparatory to killing Ian Wilkinson, and immediately and not remotely connected with killing Ian Wilkinson.

‘Three, at the time of the alleged conduct, the accused intended to kill Ian Wilkinson, and four, the accused alleged conduct had no lawful justification or excuse.’

Justice Beale also reminded the jury Austin ICU doctor Professor Stephen Warrillow gave evidence at one stage that Mr Wilkinson looked like he would die.

Justice Beale is telling the jury about the elements of murder, again explaining how the crime needed to be deliberate.

He said making and serving the deadly Wellingtons needed to be ‘conscious, voluntary and deliberate’.

Justice Beale said it could be no accident what was in dispute was: ‘Was this an accident?’

‘I’ve, in relation to my directions on the elements of murder, I’ve dealt with them collectively, but there are three charges of murder, and you have to consider the evidence in relation to each count of murder,’ Justice Beale said.

‘Understand that what’s in dispute is: was it deliberate serving up of a poison meal, and when that was done, was it done with murderous intention, an intent to kill or to cause really serious injury?’

Justice Beale also told the jury the prosecution argued Patterson was in the ‘right state of mind to deliberately murder her guests’.

Justice Beale addressed the ‘burden of proof’ and reminded the jury a person was ‘presumed innocent’.

He said Patterson did not need to prove anything, but the prosecution had to prove her guilt beyond reasonable doubt.

However, Justice Beale said not every fact needed to be proven beyond reasonable doubt.

Justice Beale also explained to the jury motive and why some cases have them and others don’t.

He said the prosecution could offer no motive here and the defence claimed there was evidence Patterson had good reasons not to kill her guests.

Justice Beale said the defence claimed Patterson had a good relationship with her in-laws, she ‘had been in a good place’ and was financially secure and happy.

‘Why would she risk throwing all that away?’ the defence argued.

But the prosecution claimed Patterson felt isolated from her in-laws and her relationship with Simon had soured.

Justice Beale said the prosecution did not need to prove motive, but he said it was relevant to Patterson’s defence.

Justice Beale said sometimes people made mistakes, but the jury needed to decide if Patterson knew her statements were untrue when she made them.

He explained to the jury about circumstantial evidence and how it works.

Justice Beale told them circumstantial evidence was ‘no weaker than other evidence’.

But he warned the jury to consider all the evidence in the case.

‘Do not guess,’ Justice Beale warned.

Justice Beale then described the trial like a jigsaw puzzle, which caused a major fit of laughter from the jury.

Mr Mandy criticised the jigsaw analogy during his closing address to the jury.

Justice Beale is taking the jury through Patterson’s claim she had a pre-surgery appointment for gastric-bypass surgery at the ENRICH Dermatology & Cosmetic Clinic.

The jury heard Patterson claimed she made the appointment for September 13, 2023 because she wanted to fix her weight problem for good.

‘I’ve been thinking about in the background doing some preparation… I’d come to the conclusion that I wanted to do something once and for all about my weight and my poor eating habits,’ Patterson said during her evidence.

‘So I was planning to have gastric-bypass surgery, and so I remember thinking I didn’t want to tell anybody what I was going to have done.

‘I was really embarrassed about it, so I thought perhaps letting them believe I had some serious issue that needed treatment, I mean, they’d be able to help me with the logistics around the cancer, and I wouldn’t have to tell them the real reason.’

The prosecution submitted Patterson lied about the gastric-bypass claim and the accused killer agreed the clinic never offered gastric-bypass procedures.

However, Patterson claimed she may have been looking into liposuction, which the clinic did offer at that time.

The defence claimed Patterson’s account was another ‘honest mistake’ while Justice Beale said if the jury felt she lied about these things, it could help them decide if they believed whatever else she said.

Justice Beale said the jury could decide what significance to give ‘these alleged lies’, but he added just because she told a lie she was not ‘guilty’

He said the lies were only relevant in assessing Patterson’s ‘credibility’.

The jury heard Don Patterson had also spoken about Erin Patterson revealing she had a ‘positive diagnosis’ of cancer.

The defence claimed Patterson said she ‘suspected’ she had cancer and might need treatment.

Lead defence barrister Colin Mandy SC told the jury he believed Mr Wilkinson had made an ‘honest mistake’ over his account of the lunch.

Justice Beale said Mr Wilkinson believed Patterson told him she had ‘ovarian or cervical cancer’.

The jury heard Patterson had spoken about a spot on a scan which she claimed was a tumour.

‘She had asked what to do with the kids,’ Justice Beale reminded the jury.

Justice Beale said Mr Wilkinson had originally told police that Patterson said she had a ‘suspected cancer’.

But during the trial, Mr Wilkinson said he believed that Patterson had told him she had cancer and needed treatment.

‘I think she was saying she had cancer,’ Mr Wilkinson told the jury.

He claimed he had ‘understated’ to police what Patterson had said.

‘She plainly said she had some sort of cancer,’ he told the jury

‘She named a type of cancer.’

Justice Beale said the prosecution had alleged Patterson lied to the jury about what she told her guests about her medical issues.

Patterson said she led her guests to believe she might need treatment.

‘I didn’t say that I received a diagnosis,’ Patterson had told the jury.

Patterson denied telling her guests she had cancer and claimed she was ‘undergoing investigations’ surrounding ovarian cancer.

The prosecution claims Patterson simply lied to the jury about what took place, suggesting she did tell them she had been diagnosed with cancer.

The jury previously heard the prosecution suggested Patterson lied about her cancer claim because she believed ‘the lie would die with her guests’.

Justice Beale is detailing for the jury the accounts of various witnesses and their evidence about why the lunch was arranged.

The court heard Patterson had wanted to thank Heather Wilkinson for being kind to her when her daughter was younger.

Simon Patterson had previously told the jury his estranged wife had invited him to the lunch to share ‘important medical news’.

Justice Beale said Simon pulled out of the lunch the night before, which caused Patterson to send him a stern message.

Ian Wilkinson, who fell ill but survived the lunch, told the jury Patterson announced she had cancer during the meal and asked for advice on how to tell her children.

Mr Wilkinson said he believed that was the reason he had been invited to the lunch.

Child protection worker Katrina Cripps told the jury Patterson informed her that she invited her guests to the lunch to ask for some advice on a ‘medical issue’.

Justice Beale told the jury the reason Patterson gave for holding the fatal lunch was an ‘alleged lie’, according to the prosecution.

The jury heard Patterson claimed the lunch was arranged simply because her in-laws had enjoyed a previous meal.

However, the prosecution claims Patterson lured her guests to lunch to share ‘important medical news’ and seek advice on how to break that news to her children.

Justice Beale is now talking the jury through Patterson’s alleged ‘credit lies’.

The first topic discussed was Patterson’s claim, made during her police interview, that she had been ‘very, very helpful’ to the health department.

The jury heard health department officer Sally Ann Atkinson gave evidence Patterson was ‘nonresponsive’ to her phone calls and text messages while the department investigated the source of the mushrooms.

Justice Christopher Beale has recommenced his final address to the jury – known as the judge’s ‘charge’ – on what is the final day before jurors deliberate over whether accused mushroom murderer Erin Patterson is guilty or not guilty.

Patterson, who is today wearing a white top with black stripes in court, listened as ‘jury keepers’ swore an affirmation before Justice Beale.

The three jury keepers will oversee the jury’s deliberations to ensure they are conducted properly.

Justice Christopher Beale reminded the jury Erin Patterson didn’t have to give evidence.

The defence previously submitted Patterson was ‘subjected to a lengthy cross examination’ which lasted five days.

‘She was careful, pedantic at times, you wouldn’t have had the impression that she was trying to charm you, persuade you,’ Mr Mandy said of his client’s time in the witness box.

‘She came through unscathed.’

Justice Beale made the comments on Friday, before sending the jury home early for the weekend.

‘Don’t let anybody get in your ear over the weekend,’ Justice Beale warned.

‘Only discuss this case with fellow jurors. Have a media blackout as far as you’re concerned.

‘You’ve been doing a great job, keep going.’

The trial will resume at 10.30am.

Justice Beale said he wanted to ‘focus on confirmed lies’ which would help the jury ‘assess Patterson’s credibility’ while he gave directions to the jury on how to assess the alleged incriminating conduct.

‘You can use the fact she lied to help determine the truthfulness of things she said,’ he said.

Justice Beale told the jury if they believed she lied to cover up the crime, they still needed to stake into account all of the evidence observed during the trial.

‘It includes, as you know, alleged lies,’ Justice Beale said.

‘I will concentrate on the alleged lies for a moment because there are two ways you can use them if you find there were lies and there were some admitted lies.

‘That is not to say just because you find the accused lied about one matter, you must also find she has been lying about everything else.’

Justice Beale told the jury they needed to consider if Patterson behaved the way she did because she feared she looked guilty.

He then turned to ‘alleged credit lies’, which he explained assess the credibility of the accused.

Justice Beale said if the jury believed Patterson told lies they could use it against her credibility.

Justice Beale is now referring to a German article on death cap mushroom poisonings which was previously mentioned in evidence.

The article included a severity grading of amanita poisoning – the toxic ingredient of a death cap mushroom.

The jury heard Grade 4 is the most serious and often ends up fatal for patients, but Grade 1 says ‘patients exhibit gastrointestinal phase with typical delay, but do not develop signs of liver or kidney dysfunction’.

Dr Dimitri Gerostamoulos (pictured) gave evidence about the article, and under cross-examination Mr Mandy asked the expert witness about ‘explanations for differences in reactions’ to death cap poisoning.

Dr Gerostamoulos said factors that may explain different reactions of individuals who have eaten the same meal include variations in concentration of toxins, how much of the meal was consumed, general health, weight, age and ‘toxic tolerances’.

Mr Mandy asked the expert if two adults, with no serious pre-existing health conditions, consumed the same amount and same meal, which contained death cap mushrooms, and one person died, what would he expect the health outcomes to be for the person who did not die?

Dr Dimitri Gerostamoulos said: ‘It would be likely that there would be some adverse outcomes for that person who survived.’

Justice Beale reminded the jury in Victoria last year that there was an incident where two people consumed the same meal containing death cap mushrooms where one person died while the other one was ‘significantly ill’ for a period and ended up in the ICU.
