When Erin Patterson Walked Into the Hospital

When Erin Patterson walked into a small rural hospital in Victoria, Australia, Dr. Chris Webster knew instantly he was dealing with more than just a routine case of food poisoning. He suspected something far worse.

“I knew it. You did it. You poisoned them.”

That very morning in July 2023, before an unexpected trip to Essex, Dr. Webster had been treating two patients—Heather and Ian Wilkinson—who appeared to be suffering from a severe case of gastroenteritis. It would later emerge that Erin Patterson had knowingly prepared a Beef Wellington laced with poisonous mushrooms for four of her former in-laws. Three died. One survived.

The Deadly Dinner: What Happened?

Erin was found guilty of murdering Don and Gail Patterson—her ex-husband’s parents—and Gail’s sister, Heather Wilkinson. She was also convicted of the attempted murder of Heather’s husband, Reverend Ian Wilkinson, who barely survived after spending weeks in intensive care.

Initially, the symptoms resembled a typical foodborne illness. But when Dr. Webster asked Heather about the meal, she simply said it tasted “delicious.” Trusting his gut, he ordered blood samples for analysis and started IV fluids.

Shortly after, he received a call from another hospital—where Don and Gail were being treated. Their doctor warned him:

“It’s not the beef — it’s the mushrooms. They’re dying.”

Arrival of the Suspect Was Unexpected

Just as Dr. Webster was preparing to transfer his patients to a regional referral center, a new patient arrived at the hospital: Erin Patterson. She claimed she was experiencing stomach trouble.

“I asked her name. She said, ‘Erin Patterson,’ and that’s when I knew. She was the one who had made the meal,” Dr. Webster said.

When asked where the mushrooms came from, Erin simply replied:

“Woolworths” — a major Australian supermarket.

This raised immediate concerns. While foraging wild mushrooms is a local tradition, attributing the source to a commercial grocer with strict food safety standards seemed suspicious.

What troubled Dr. Webster even more was Erin’s demeanor.

“There was very little concern for the critically ill loved ones lying just a few meters away.”

The Doctor Calls the Police

Soon after, Erin discharged herself from the hospital. Dr. Webster attempted to reach her by phone, but when she didn’t respond, he contacted the police.

In a recording later played in court, he stated:

“I’m Dr. Chris Webster from Leongatha Hospital. A possible mushroom poisoning patient has just left.”

Erin eventually returned to the hospital voluntarily. Dr. Webster urged her to bring in her children—who she said had also eaten leftovers from the same dish. She hesitated.

“I said, ‘They can be scared and live, or not be afraid and die.’”

Follow-up tests showed no signs of mushroom poisoning in Erin or her children, and all were discharged after 24 hours of precautionary observation.

Justice and Closure

Now, two years later, Dr. Webster received the news: the jury had delivered a guilty verdict. He had served as a key prosecution witness.

“I felt relief. Like justice had been done,” he said. “It was heavy—every small piece of evidence had to fit. If one part cracked, the case could fall apart.”

But his most meaningful moment came when he finally saw Ian Wilkinson—the only survivor—standing and smiling.

“That was the moment,” he said. “To see him alive—that brought peace.”
