Footage of Erin Patterson being interviewed by detectives after her deadly mushroom lunch can now be shown for the first time.

The recording, which was taken at Wonthaggi Police Station on August 5, 2023, was among a tranche of documents and exhibits that have been released to the media after the Victorian Supreme Court lifted a suppression order on Friday.

Patterson was taken to the police station to be questioned hours after officers investigating the deaths of her former-in-laws — Don and Gail Patterson, both 70, and Gail’s sister Heather Wilkinson, 66 — searched her Leongatha home.

The trio died and Heather’s husband Ian Wilkinson, 70, fell gravely sick but survived after the two couples attended Patterson’s home in Victoria’s Gippsland region for a beef wellington lunch laced with toxic death cap mushrooms on 29 July, 2023.

The interview begins with Patterson agreeing with Homicide Squad Detective Sergeant Stephen Eppingstall that the time is 4.31pm by his watch.

She then provides him with her full name and address.

Eppingstall: “Erin, I intend to interview you today in relation to the death of two people, being Gail Patterson and Heather Wilkinson. Before continuing, I must inform you (that) you do not have to do or say anything and anything you say or do is being recorded and may be used as evidence in court.

“Do you understand that information?”

Patterson: “Yeah,” she said silently as she nodded her head.”

Eppingstall further advised Patterson that she may inform a friend or relative of her whereabouts or make contact with a legal representative.

Asked whether she understood her rights, Patterson said yes.

Eppingstall: “Do you wish to exercise any of these rights?”

Patterson: “No, I don’t. “

Patterson confirmed that she had spoken to a solicitor before the interview and was happy to proceed.

Eppingstall then asked Patterson a series of questions about her personal details, including her age, date of birth, and residency status.

Asked to provide her phone number, Patterson gave Eppingstall a number ending in “835”, which the jury at her murder trial heard was not her regular phone number (which ended in 783).

Eppingstall: “As we discuss earlier, and we have been together for a few hours now... we want to discuss the deaths of Heather Wilkinson and Gail Patterson with you.

“We were at the house and we discuss that you hadn’t really been kept in the loop and it came as news to you that Heather and Gail had both passed away.

“Following eating at your house, Donald, Ian, Gail and Heather all became so well they ultimately ended up in the intensive care unit at both the Dandenong hospital then moved to Dandenong Hospital. Following that, they had a deterioration in their condition.. they had become so ill that their livers failed.”

Eppingstall told Patterson that Don had undergone a liver transplant overnight, leading the mother-of-two to widened her eyes in apparent shock, before looking down towards her hands as the officer continued to speak.

Eppingstall: “His condition was is still extremely critical...Heather and Gail passed away. In relation to Ian, I don’t have a current prognosis as to where he is at. As of late yesterday, his diagnosis isn’t great for him either.”

“We are trying to understand what has made them so ill.”

Patterson: “Mmm.... Yeah,” she said, nodding her head and looking to towards Eppingstall.

Eppingstall: “Which is why we are asking these questions.”

“The other thing conversely that we are trying to understand is why you are not that ill.

“So do you understand why we are here today?”

Patterson told Eppingstall she did, but that she had been “helpful” so far with their investigation.

Patterson: “I’m sure you understand, too, that I have never been in a situation like this before and I have been very very helpful with the health department through the week because I wanted to help that side of things as much as possible.

“I do want to know what happened, so I have given them as much information as they have asked for and offered up all the food and all the information about where the food came from.”

Eppingstall noted that Patterson was helpful with police during the search that morning at her house and she pointed out a few things that would be useful for their investigation, such as the fruit platter Heather brought to the lunch and a gravy that was in the fridge.

He said she also pointed out a recipe book on the counter and showed officers the beef wellington recipe she used to cook the meal served at the lunch.

Eppingstall: “We didn’t see a lot of food from Asian grocers or Indian grocers or those kinds of stores?”

Patterson interjected: “Did you look in my fridge? I have a lot of Asian cooking stuff in my fridge.”

Eppingstall: “Yep.”

The detective asked Patterson if officers would be likely to find more Asian food or ingredients at her Mount Waverley townhouse in Melbourne, where she would sometimes holiday with her children.

But Patterson said that she did not think they would, because she had cleaned out the pantry with plans to sell that property.

Eppingstall: “So obviously we have concerns about these mushrooms and where they have come from. Is that something you have done in the past? Foraging for mushrooms?”

Opening her eyes wide, Patterson stared directly at Eppingstall and said: “never.”

Eppingstall: “Did you preserve food or anything like that?”

Patterson: “No.”

Eppingstall: “Have you ever dehydrated food or anything like that?”

Patterson: ”No.”

Eppingstall: “Ok.”

Eppingstall said Patterson had previously described her relationship with her ex-husband, Simon, and that he wanted to understand why she chose to have his parents, uncle, and aunt over for lunch.

Patterson claimed she invited them over because she has “no other family”.

Patterson: “They are the only support I’ve got less. They’ve always been very good to me. I want to maintain my relationships with them despite what has happened with Simon. I love them a lot.

“They have always been very good to me and they have always said they would support me even though Simon and I were separated and I really appreciated that because both of my parents are both gone.. My grandparents are all gone... They are the only family (she said, using her fingers to indicate quotation marks) that I have got.”

“They are the only grandparents my children have and I want them to stay in my kids’ lives. And that’s really important to me. I think Simon hated that I still had a relationship with his parents, but I loved them.

“Nothing that has ever happened between us will change the fact that they were good, decent people who have never done anything wrong to me, ever.”

Eppingstall asked Patterson why she only went to Leongatha hospital for five minutes on the morning of July 31, 2023 (two days after the lunch) before leaving.

The mother of two claimed she went there because she was dehydrated and they said they wanted to admit her and send her a Melbourne hospital, but she had animals at home and children’s after school activities to organise.

Patterson: “So I had to go home and feed the animals, and pack my daughter’s bag, and I did that.’

Eppingstall asked Patterson who she spoke to when she went to the hospital, and she explained she spoke to a nurse and asked her for directions to the toilet because she had diarrhoea.

Patterson: “I went to the toilet, I came back out, I was waiting in triage area, and a doctor came out and he said we are going to be a little while because we have a few patients in our hospital, and I said don’t worry about me, I’m just a gastro case.

“He said what is your name, and I said “Erin Patterson” and he said “aww we have been expecting you because other people who you ate with on Saturday are sick.”

Patterson said she agreed to follow the doctor to another area to speak to him and he informed her there was a concern the lunch guests had consumed death cap mushrooms.

Patterson: “And I said ‘what?’”

“And then he asked me about what they had eaten and I told him.”

The jury in Patterson’s trial heard she later returned to the hospital almost two hours later.

Asked by Eppingstall what treatment she had received, she explained she was given medication to protect her liver before she was transferred to Monash Hospital.

Eppingstall explained to Patterson that they had obtained her medical records and officers would go over the details as part of their investigation.

He then took her through some of the items seized from her home earlier that day during the search, including a manual for an electric food dehydrator.

Eppingstall: “Do you know anything about a dehydrator?”

Patterson: “No.”

Eppingstall: “Do you own a dehydrator?”

Patterson: “No. I have manuals for lots of things that I have collected over the years.”

Eppingstall: “When did you own a dehydrator.”

Patterson: “I don’t know,” she said, appearing to be trying to recall.

“I may have had one years ago. When I first got the thermomix, I got excited about making lots of things from scratch.. I did a lot of that.. So it might have been something from back then.”

Eppingstall said detectives had seized the RecipeTin Eats book, a white jug of brown liquid from the butler’s pantry, and afruit platter.

He said they also took a computer, some Samsung tablets, and a few mobile phones.

Patterson was found guilty of three counts of murder and one count of attempted murder last month.

She is being housed at Melbourne women’s prison, Dame Phyllis Frost Centre, as she awaits her sentencing hearing later this year.
