Death Cap Dinner: The Leongatha Mushroom Murders & Erin Patterson

Unknown speaker 00:04 Stories, fables Ghostly Tales The Bodies Disclaimer This episode is based on publicly available documents and reporting, as well as court documents, as of the 14th December 2025. A country lunch that broke the internet. Unknown speaker 00:41 On a winter Saturday in country Victoria, four adults sit down to a homemade lunch in a quiet town called Leon Gartha. Nothing about the invite looks unusual. It’s family. It’s a nice house. The main course is Beef Wellington. Unknown speaker 00:58 Yum. A bit fancy for a small town, but hardly suspicious. Within a week, three of those people are dead. The fourth has been airlifted, put through the medical ringer, and somehow clings on. The alleged weapon? Unknown speaker 01:14 Not a gun. Not a knife. A mushroom. Yes. Specifically, what toxicologists and fungi experts later tell the court is Amanita fallodius, the death cap mushroom, one of the most poisonous in the world. This is Australia. Unknown speaker 01:36 Usually when we argue about mushrooms, it’s should they go on pizzas, not should they go in a Supreme Court murder trial. But in 2025, that is exactly what happens. So how did the case start? The people involved, the motive, and what the death cap mushroom actually does to your body. Unknown speaker 01:56 And that’s what we’re covering today. According to the Supreme Court of Victoria and trial reporting, the lunch took place on the 29th of July 2023 at the home of Erin Trudy Patterson in the town of Leongarthur in South Gippsland. Unknown speaker 02:11 At the table were four guests, all related to her through marriage. Don Patterson, her former father-in-law, Gail Patterson, her former mother-in-law, Heather Wilkinson, Gail’s sister, Ian Wilkinson, Heather’s husband, a local pastor. Unknown speaker 02:24 Erin’s estranged husband, Simon Patterson, had been invited but did not attend. And you’ll find out why later on. Her two children were around that day, but according to evidence summarised in court, they did not eat the main course with the adults. Unknown speaker 02:40 They went to the movies instead. The main dish, as the Crown later describes it, was individual beef Wellingtons, steaks wrapped in pastry and a mushroom duxel, served with potato and vegetable. We now know the who, but what actually happened. Unknown speaker 02:57 And here we have to be very clear. This is about what the prosecution argued. According to Routers and the Supreme Court summary, prosecutors said that this was not food poisoning gone wrong or some weird takeaway disaster. Unknown speaker 03:10 They told the jury this was a deliberate poisoning, rooted in ongoing family tensions and a pattern of deception, including a false story about Erin having cancer to manipulate sympathy and draw people closer. Unknown speaker 03:22 The law doesn’t require the Crown to prove a detailed, crystal-clear motive. They just have to prove intent. But they pointed to that claimed illness, to strained family relationships, and to earlier alleged incidents involving food and errant estranged husband. Unknown speaker 03:37 Those earlier accounts were later dropped as the backdrop. The defense, for their part, would eventually say this was a tragic accident, a mushroom mix-up by an amateur forager who then panicked and lied. Unknown speaker 03:51 So from the beginning, the story splits into two. The Crown says this was a targeted mushroom attack, and the defense says this was a catastrophic mistake. That I can agree. And the jury has an unenviable position of having to pick one of them. Unknown speaker 04:08 So what was the initial defense and how did it all fall apart? When people start dropping with catastrophic liver damage right after eating at your house, the health department calls you. Investigators from Victoria’s Health Services and Police talk to Erin in the days after the lunch. Unknown speaker 04:24 The version of the events they hear early on, as reported in ABC’s trial coverage, sounds roughly like this. The mushrooms came from supermarkets and an Asian grocer. She was not a mushroom forager. She did not own a food dehydrator. Unknown speaker 04:40 Now, hold on to the last one for later. In short, I bought normal mushrooms like everybody else. I don’t go wandering into the forest with a basket. The problem with that story is that it collides head on with two sets of facts. Unknown speaker 04:55 In Victoria, public health advice in Victoria says death caps are not found in a normal commercial mushroom supply. They’re wild, not framed for sale. Number two, evidence starts turning up that Erin has foraged mushrooms and does use a dehydrator. Unknown speaker 05:15 So the earlier I just bought them at the shops defense lasts right up until investigators check the tip. This is one of those moments where real life looks like a dark comedy writer got hold of the script. Unknown speaker 05:28 In crime shows, people toss guns off bridges. In this Australian case, though, it’s a kitchen appliance at the dump. CCTV from the Kunawara landfill shows Erin driving in on 2nd of August 2023, four days after the lunch, and dropping a Sunbeam food dehydrator into the e‑waste area. Unknown speaker 05:49 Bank records confirm she paid a fee at the tip that day. Police go back, retrieve the dehydrator, and send it to the lab. At trial, Erin admits she lied in her early interviews about not foraging and not owning that dehydrator. Unknown speaker 06:04 She tells the court she lied because she was ashamed, panicked and scared of being blamed. The story has changed. The question now is whether the jury believes the new version. Now let’s look at the damning evidence. Unknown speaker 06:20 This is the part of the story that jurors spend weeks listening to, the science, the photos, and the digital crumbs. Let’s hit the key pieces that courts and major outlets all highlighted. So the dehydrator is first up. Unknown speaker 06:35 The tip run, so to speak. Forensic experts test the inside of that sunbeam dehydrator and find mushroom DNA that, according to the fungal specialist evidence, is a 99% match for death cat mushrooms. The Supreme Court summary notes that the jury accepted the prosecution’s case that death cat mushrooms had been preserved in that dehydrator and then used in the meal. Unknown speaker 06:59 Small, grim side note, imagine having a job where you spend your days scraping goo out of a dump rescue dehydrator and going, yep, that’s lethal fungus. Mycologists are really the unsung horror protagonists. Unknown speaker 07:16 The next evidence is the photos. Police also find photos on a device from the Patterson home. Mushrooms on a set of kitchen scales. Those images are shown in court to a fungi expert. His evidence, reported in ABC’s coverage, is that the mushrooms in those photos are death caps with a high degree of confidence. Unknown speaker 07:36 So now you’ve got death cap matching DNA in the dehydrator, Erin dumped, and death caps on scales in a kitchen, captured in photos tied to the household. If this were a cooking show, this is the part where the host says, here’s one I prepared earlier, and everyone goes quiet. Unknown speaker 07:52 The Medical and Toxicology Trail. Toxicologists and treating doctors testify that the four guests showed a pattern consistent with amatoxin poisoning, the signature toxins in death caps. According to those reports, Don Patterson received a liver transplant, but still dies from liver and multi-organ failure, my goodness. Unknown speaker 08:13 Gail Patterson and Heather Wilkinson also dies from liver failure complications within six days. Ian Wilkinson is in hospital for around seven weeks and survives. Tests detect amatoxins consistent with death caps in at least some victim samples. Unknown speaker 08:31 Meanwhile, samples associated with Erin and her children do not show the same death cap toxins. The crown leans hard on that asymmetry. Four guests are poisoned. The cook is not. The kids are not. The toxins showed up in them, but not in her. Unknown speaker 08:48 The defense, for their part, cross-examines the experts, pointing out limitations and timing issues in some of the tests, and reminding the jury that the science isn’t always perfectly clean. But there is a bigger pattern. Unknown speaker 09:02 All of this sits on top of the earlier lies. Erin originally saying she never foraged and never owned a dehydrator. Later accepting that yes, she did indeed forage and yes, she did indeed own a dehydrator, particularly used for mushrooms. Unknown speaker 09:21 Prosecutors also tell the jury she falsely claimed to have cancer when in fact she was planning weight loss surgery, using the illness story to gain sympathy and explain medical appointments. So when jurors walk into the deliberation room, here’s what’s on the table. Unknown speaker 09:36 A family meal, three deaths and one near death from death cat poisoning, a dehydrator dumped at the tip with death cap DNA, photos of death cats on scales, inconsistent stories from Erin about mushrooms, medical issues and equipment. Unknown speaker 09:51 The defense says, tragic mix-up, then panic and lies. The prosecution says, that’s not panic, that’s a cover-up. The sentence. What do you think if you were given this as evidence and you were one of the jurors? Unknown speaker 10:05 On the 7th of July, 2025, after hearing all of that, a jury finds Erin Patterson guilty of three accounts of murder for Don, Gail, and Heather. One count of attempted murder for Ian. Two months later, on the 8th of September, 2025, she comes back for Justice Christopher Bailey for sentencing. Unknown speaker 10:24 But before I go into the guilty sentencing and the overall sentencing for Erin, I want to jump into the motivation that spurred all this. It’s one thing to know what was done and how that person is to be treated after the fact. Unknown speaker 10:38 But what drives a person to do this? In the official record, the most haunting thing about this case isn’t actually the mushrooms or the tip run or even the trial. It’s the silence around why. Even at sentencing, Justice Christopher Bealey looked at Aaron Patterson and said, in open court, only you know why you committed them. Unknown speaker 11:00 I will not be speculating about that. So we’re going to be doing what the judge wouldn’t. Carefully walk around the edges of motivation. Not to pretend we’ve solved it, but to explore the shape of whatever was sitting in her hair that day. Unknown speaker 11:13 Again, purely conjecture and an opinion. So let’s begin. First, by understanding what happens to your body when you consume a death cat mushroom. Then we’ll explore the relationship with Erin and her ex-husband. Unknown speaker 11:28 So folded into a sauce, diced into a ductile, sliced on top of something comforting, you chew, you swallow, you drink your water or your wine, and for a while, absolutely nothing feels wrong. That’s the first trick of a death cat mushroom. Unknown speaker 11:43 For the first hours, your body behaves like this was just dinner. Inside your stomach, the mushroom is breaking down and with it, a family of tiny, vicious molecules called amatoxims. They are small, tough rings of amino acids that don’t care about heat or cooking or stomach acid. Unknown speaker 12:01 Boil them, fry them, bake them into pastry. They survive. They slip through the wall of your gut, into your bloodstream, and catch a ride straight to the organ that waits at the end of nearly all digestive roads, your liver. Unknown speaker 12:14 Your liver is a quiet workhorse. It cleans your blood, manages your chemistry, keeps the entire system in balance without drama. The amatoxins arrive at its doorstep like polite guests and they walk in with a can of petrol. Unknown speaker 12:28 They do something very precise. Inside liver cells, they block the machinery that makes new proteins. The little enzymes that turns DNA instructions into messenger RNA and from there into thousands of proteins that keep a cell alive and able to repair itself, cut that off and the cell doesn’t explode straight away. Unknown speaker 12:48 It just can’t fix anything anymore. It starts dying from the inside out. All of this is happening quietly, molecule by molecule, as you wash the meal down and maybe compliment the cook. You feel nothing. Unknown speaker 13:03 Several hours later, the storm announces itself. It starts like a bad joke your body is telling at your expense. Twisting, cramping pain in your gut. Nausea that climbs up from somewhere low and deep. Unknown speaker 13:17 Then vomiting again and again until it feels like your insides are trying to leave. The other end joins in. Profuse, watery diarrhea. The kind that strips fluids and electrolytes out of you so fast you can feel yourself drying out. Unknown speaker 13:32 Sweat, chills, stomach cramps like someone’s wringing your intestines out like a towel. If you stumble into an emergency department at this point, you look like a hundred other cases. Maybe food poisoning, maybe a viral gastrobug, maybe something you ate. Unknown speaker 13:48 No glowing green aura, no obvious clue that this is anything more than a savage but ordinary tummy illness. But while your gut is throwing its tantrum, the deeper story is in the blood. The amatoxins are still hammering the liver. Unknown speaker 14:01 Cell after cell is losing its ability to repair damage, to process toxins, to make the proteins that keep your blood from leaking and your chemistry from swinging wildly out of range. It’s like a city where all the maintenance crews have just been fired. Unknown speaker 14:15 At first, nothing looks different from the outside, but the cracks are already forming. This early storm can last a day. You’re miserable, exhausted, hugging toilets and dripstands, but your mind is in the same place where most people would be. Unknown speaker 14:29 This is horrible, but it’ll pass. And then, in a way, it does. One of the cruelest things about death cat poisoning is the false dawn. After the vicious first act, the vomiting eases. The diarrhea slows. Unknown speaker 14:45 The cramps let go. You can keep down some water, maybe a little food. Nurses say you’re looking better. You might even sit up, scroll your phone, tell someone, I think I’m coming good now. From the outside, it looks like recovery. Unknown speaker 14:59 On the inside,
