Erin Patterson: CCTV released of mushroom cook killer dumping dehydrator after fatal lunch

Footage of the moment triple-killer Erin Patterson dumped her dehydrator at a local tip has been released by Victoria’s Supreme Court.

The CCTV footage, spanning 47 seconds, captures Patterson arriving at the Koonwarra Transfer Station in the morning of August 2, 2023, in her red MG SUV and carry the black bulky item directly into a shed.

The 50-year-old mother of two was found guilty last month of murdering three of her husband Simon Patterson’s relatives, and the attempted murder of a fourth, with a poisoned beef wellington just days earlier on July 29.

Simon’s parents, Don and Gail Patterson, and Gail’s sister Heather Wilkinson died from death cap mushroom poisoning in the week following the lunch while Heather’s husband, Ian Wilkinson, survived.

During her trial, the jury was shown the footage as police described locating the Sunbeam Food Lab dehydrator in the tip’s e-waste bin on August 4.

It was later found to contain remnants of death cap mushrooms.

The court was told Patterson’s trip came the morning after she was released from Monash Hospital on the afternoon of August 1.

On the stand, Patterson claimed she dumped the dehydrator in a panic after Simon allegedly confronted her in hospital — an incident he says never happened.

“He said to me, ‘Is that how you poisoned my parents, using that dehydrator?’” she said.

Patterson claimed she realised soon after she might be wrongly blamed for the deaths and took steps to hide evidence.

The jury heard Patterson had purchased the dehydrator just two months earlier on April 28 and shared with friends online she’d been hiding dehydrated mushrooms in everything.

Footage has been released of the moment Erin Patterson was asked to hand over her mobile phone to investigators as they searched her Leongatha home.

“I’ve been hiding powdered mushrooms in everything. Mixed it into chocolate brownies yesterday, the kids had no idea,” one message reads.

Another said; “So fun fact the dehydrator reduces mushroom mass by 90 per cent. Do you think Woolies would mind if I put the dehydrator into their vegetable section and dry things before I buy them.”

At trial, Patterson maintained she was innocent and did not intentionally poison anyone.

Instead, the jury heard, the case was a tragic foraging accident with wild mushrooms inadvertently making their way into the beef wellington lunch. Patterson is set to return to the Victorian Supreme Court on Friday, where it’s expected a date will be listed for a pre-sentence hearing.
