Erin Patterson trial: Phone placed in vicinity of Loch, Outtrim after death cap sightings
Accused killer Erin Patterson's mobile phone pinged cell towers near a location where death cap mushrooms had been spotted, a court has been told.
Giving evidence at Ms Patterson's triple-murder trial on Monday, Digital Forensic Sciences Australia's Dr Matthew Sorrell told the court he sifted through more than four years of her phone records.
Dr Sorrell said he was tasked with finding potential visits to the Loch and Outtrim areas — two townships near Ms Paterson's Leongatha home where the deadly mushroom had been observed.
Earlier in the trial, two witnesses gave evidence they located death cap mushrooms in those towns and posted details including a precise location on citizen science website iNaturalist.
Christine McKenzie said she posted the mushrooms on April 18, 2023, in Loch, while Dr Tom May posted a sighting of death caps in Outtrim on May 21 the same year.
Dr Sorrell told the jury Ms Patterson's phone could have possibly visited Loch between 9.14am and about 10am on April 28.
He said the records indicate movement out of Korrumburra, connecting to Loch and a return to Korrumburra, but there was an 'absence' of records for the middle of that period.
'While there is a potential visit, it doesn't definitely point to being in the Loch township,' he said.
On May 22, Dr Sorrell said the phone records indicate potential visits to both Loch and Outtrim.
He said Ms Patterson's phone connected with the Loch South base station 'every five minutes' from 9.19am until about 10am.
Later the same morning, he said the records indicate support the opinion the phone could be in the northern section of Outtrim' between 11.24am and 11.49am.
Dr Sorrell is expected to face cross-examination from Ms Patterson's defence when the trial resumes on Tuesday.
Ms Patterson is facing trial after pleading not guilty to the murder of three of her husband's relatives and the attempted murder of one more.
Simon Patterson's parents, Don and Gail Patterson, and his aunt Heather Wilkinson died from death cap mushroom poisoning in the week after eating a beef wellington at Ms Patterson's home on July 29, 2023.
Heather's husband, Ian Wilkinson, recovered after spending a month and a half in hospital.
Prosecutors allege Ms Patterson deliberately spiked the lunch with 'murderous intent', while her defence argues the case is a 'tragic accident'.
The trial continues.

Key revelations from mushroom cook's testimony
The Victorian mother-of-two at the centre of a mushroom poisoning case had the opportunity to tell her own story this week as she took the stand at her triple-murder trial. Erin Patterson, 50, is facing trial after pleading not guilty to the murders of her husband's parents and aunt, and the attempted murder of his uncle. Simon Patterson's parents, Don and Gail Patterson, and Gail's sister, Heather Wilkinson, died in the week after the lunch after falling ill from mushroom poisoning. Prosecutors alleged she deliberately poisoned the beef Wellington lunch on July 29, 2023, with death cap mushrooms intending to kill or seriously injure her four guests. Erin Patterson and her estranged husband Simon Patterson. NewsWire Credit: NewsWire Her defence, on the other hand, has argued the case is a 'tragic accident' and Ms Patterson also consumed the death caps and fell sick, though not as sick as her guests. Over five days this week Ms Patterson sat in the witness box about 7 m from the 14 jurors selected to hear her case, answering questions, firstly from her barrister Colin Mandy SC and then from Crown prosecutor Nanette Rogers SC. Her opportunity to tell her own story came after the jury spent five weeks hearing from more than 50 witnesses for the prosecution as Ms Patterson sat in silence at the back of the Morwell courtroom. Mushroom cook agrees death caps in lunch may have been foraged In her testimony to the jury, Ms Patterson conceded death cap mushrooms 'must' have ended up in the beef Wellington lunch she prepared and served for the four guests. The morning of the lunch, she told the court, she started to prepare the duxelles, or mushroom paste, by cooking down two punnets of fresh sliced mushrooms she had purchased from Woolworths. 'So, as I was cooking it down, I tasted it a few times and it seemed a little bland to me, so I decided to put in the dried mushrooms that I'd bought from the grocer that I still had in the pantry,' she said.

NewsWire / Anita Lester Credit: News Corp Australia Ms Patterson told the jury she had purchased a packet of dried mushrooms in April the same year from an Asian supermarket in Melbourne, initially intending to use them for a pasta dish but deciding against that because they had a strong flavour. She said she now accepts it was possible she had stored wild mushrooms she foraged from her local area and dehydrated in the same Tupperware container. 'At that time, I believed it was just the mushrooms that I'd bought in Melbourne … Now I think that there was a possibility that there were foraged ones in there as well,' she said. Ms Patterson told the jury she first became interested in foraging for wild mushrooms during Covid and educated herself online. Crown prosecutor Nanette Rogers SC is leading the case against Ms Patterson. NewsWire/ David Crosling Credit: News Corp Australia Over a period of months, she said she grew confident to identify 'field mushrooms and horse mushrooms' growing on her property before deciding to eat some. 'When I got to a point I was confident what they were, I cut a bit off, fried it up with butter, ate it and saw what happened,' she said. 'They tasted good and I didn't get sick.' Ms Patterson said she had purchased a dehydrator on April 28, 2023, to begin experimenting with preserving mushrooms because they had a short shelf life. Crown alleges photo shows Ms Patterson calculating 'fatal dose' Under questioning from Crown prosecutor Nanette Rogers SC, Ms Patterson was taken to a photograph of sliced mushrooms on a dehydrator tray being weighed. The weight recorded was 280.0g and metadata from the photo showed it was last modified on May 4. Ms Patterson agreed the photo was 'likely' taken by her and contains her kitchen bench.

Questioned on if she accepted the mushrooms pictured were death caps, Ms Patterson said: 'I don't think they are'. She also denied she had foraged these mushrooms in the nearby town of Loch on April 28 after seeing a death cap mushroom sighting post on citizen science website iNaturalist on April 18. Dr Rogers suggested the image recorded Ms Patterson weighing the mushrooms to calculate the 'weight required for the administration of a fatal dose'. 'Disagree,' Ms Patterson responded. The trial is being heard in the country Victorian town of Morwell. NewsWire / Josie Hayden Credit: News Corp Australia Mushroom cook tells jury she lied to health authorities because she was scared Ms Patterson said she first learned her in-laws had fallen ill the day after the lunch on a phone call with her estranged husband on July 30. The following day, she told the court, she attended the local Leongatha Hospital too seek treatment for gastro when the resident doctor, Dr Chris Webster, said 'we've been expecting you'. 'I think I said to him, 'Why? Why are you asking?', and he said that there's a concern or we're concerned you've been exposed to death cap mushrooms,' she said. 'I was shocked but confused as well … I didn't see how death cap mushrooms could be in the meal.' Crowds have lined up outside the court to sit in the public gallery. NewsWire/ David Crosling Credit: News Corp Australia Ms Patterson told the court she first began to suspect foraged mushrooms may have ended up in the lunch at Monash Medical Centre when Simon accused her of poisoning his parents. In his own evidence, at the start of the trial, Simon Patterson told the jury he did not say this to his wife. Ms Patterson told the jury on August 2, the day after her release from hospital, she disposed of her dehydrator at the Koonwarra Transfer Station. 'I was scared that they would blame me for it,' she said of the decision. 'Surely if you loved them (her in-laws) you would have notified health authorities about the possibility of the foraged mushrooms in the container?' Dr Rogers asked. 'Well I didn't,' Ms Patterson replied. 'I had been told people were getting treatment for possible death cap mushroom poisoning so that was already happening.' Erin Patterson appeared emotional at times on the stand. Brooke Grebert-Craig. Credit: Supplied Ms Patterson confirmed she did not notify anyone of her suspicions and lied to both police and health authorities in the following days by claiming she did not forage for mushrooms. She was taken to a series of messages exchanged with public health officer Sally Anne Atkinson, where Ms Patterson insisted the only mushrooms in the meal were from Woolworths and an Asian grocer. Asked what her state of mind was in relation to the Asian grocer, she said she 'still thought it was a possibility, but I knew it wasn't the only possibility.' Ms Patterson told the court she first learned of Heather and Gail's deaths as police searched her home on August 5 and continued to lie. 'It was this stupid knee-jerk reaction to just dig deeper and keep lying. I was just scared, but I shouldn't have done it,' she said. Simon's parents Don and Gail Patterson died a day apart in early August. Supplied Credit: Supplied Ms Patterson claims she vomited after deadly lunch Ms Patterson also told the jury she had long struggled with both her weight and relationships to food since childhood – describing it as a 'rollercoaster'. 'Mum would weigh us every week to make sure we weren't putting on too much weight … I went to the extreme of barely eating then to, through my adulthood, going the other way and bingeing,' she said. She told the court she had engaged in binge eating until she was sick then 'bringing it back up' since her 20s and no one knew.

She told the court that at the lunch with Don, Gail, Heather and Ian, she only ate some of her serving, but consumed about two-thirds of an orange cake after her guests left. 'I had a piece of cake and then another piece of cake and then another,' Ms Patterson said. 'I felt sick. I felt overfull, so I went to the toilets and brought it back up again.' Ms Patterson is expected to return to the witness box and continue giving evidence when the trial resumes on Tuesday.

Erin Patterson live trial updates: Accused mushroom killer's admission, evidence over beef Wellington lunch
Accused triple murderer Erin Patterson will give her final defence evidence on Thursday before being cross-examined by the prosecution over her deadly, mushroom-laced, fatal beef Wellington lunch. Scroll down for the latest updates, live from inside the courtroom of Erin Patterson's triple murder trial. A power issue at the Morwell court in regional Victoria has delayed this morning's proceedings. It is understood this has been resolved and the trial will resume shortly. Erin Patterson has told the court how she disposed of her food dehydrator at a tip as she feared her children would be taken away from her, as authorities circled following the death cap mushroom-laced lunch. Ms Patterson claimed the majority of mushrooms in her beef Wellington were from a local Woolworths in Leongatha; however, after tasting her 'bland' mix, she added dried mushrooms from a container in her pantry. The accused told the court how that container could have included mushrooms she had picked and dehydrated during her 'experiments', or potentially 'pungent' mushrooms she bought from a mystery Asian grocer in Melbourne. While she was in hospital after the lunch, Ms Patterson told the court how her ex-partner, Simon Patterson, asked her point blank: 'Is that how you poisoned my parents? Using that dehydrator?' Read the full story on Erin Patterson's evidence so far. Accused triple murderer Erin Patterson will on Thursday give her final evidence as a witness for the defence. After that, the alleged killer cook will face cross-examination from the prosecution. Ms Patterson denies intentionally killing her ex-partner Simon Patterson's family with death cap mushrooms that were inside a fatal beef Wellington lunch. Don and Gail Peterson, and Heather Wilkinson died following the lunch, with sole-surviving lunch guest, Ian Wilkinson, watching on as the accused gives evidence at the Victorian Supreme Court trial in Morwell. Ms Patterson returns to the witness box at 10.30am AEST Thursday.
