Pictures showing the toxic mushrooms and deadly beef Wellington at the centre of Australian woman Erin Patterson’s murder trial have been released by a court.

Patterson, 50, was found guilty by a jury of murdering three relatives with a fatal family meal in the small Victorian town of Morwell on 29 July 2023. She was also convicted of the attempted murder of a fourth person, who survived the meal.

The mushroom trial that gripped the country, and much of the world, heard evidence suggesting Patterson hunted down death cap mushrooms from nearby towns, before attempting to conceal her crimes by disposing of evidence and lying to authorities.

Three people died in hospital in the days after the meal: Patterson’s former in-laws, Don Patterson, 70, and Gail Patterson, 70, as well as Gail’s sister, Heather Wilkinson, 66.

Local pastor Ian Wilkinson – Heather’s husband – recovered after weeks of treatment in hospital.

Her estranged husband Simon Patterson was also invited but cancelled the day before, saying he felt “uncomfortable” attending amid tension between the former couple.

Following the guilty verdict, the Supreme Court of Victoria has released some 100 images shown to the jury as evidence during the trial.

Some of the released photos are of the beef Wellington leftovers, which were collected from Patterson’s home.

The leftovers were collected in specimen bags to prevent contamination, before being taken for examination.

The leftovers, which police found in her bin, were tested for traces of death cap mushrooms.

Death cap mushrooms are considered to perhaps be the deadliest of all mushrooms to humans, according to Britannica. The fungus is responsible for most cases of mushroom poisoning worldwide, of which some are fatal, the encyclopaedia has said.

The cap ranges in colour from greenish yellow to brown, tan, or rarely white, and measures about 4-16cm (about 1.5-6in) in diameter.

Patterson claimed she purchased some of the mushrooms dried from an Asian grocery in Melbourne, but couldn’t remember which suburb. When she was questioned about the brand, and asked for transaction records, she said the mushrooms were in plain packaging and added that she must have paid in cash.

However, detectives had discovered death cap mushrooms had been seen in two towns close to Morwell, where Patterson lived, before the meal. Concerned locals had been posting images and locations of the mushrooms on the online plant database iNaturalist.

Erin Patterson’s search history showed that she had used the iNaturalist website to view death cap mushroom sightings at least once before.

Her mobile phone location data appeared to show her travelling to both places and buying a food dehydrator on the way home.

Forensic experts were also able to recover images on her mobile showing what looked like death cap mushrooms on weighing scales.

Even a small piece of a death cap mushroom can be deadly and its toxins cannot be destroyed by cooking, freezing, or drying.

Traces of poisonous mushrooms were found in a food dehydrator that Erin Patterson disposed of in a local dump the day after she was discharged from hospital.

Patterson told police she’d never owned such an appliance, despite an instruction manual being found in her kitchen drawer and posts in a true crime Facebook group where she boasted about using it.

Among the exhibits released by the judge, are stills of Patterson dumping a food dehydrator at her local tip days after the beef Wellington lunch.

As a reminder, she took herself to the hospital two days after the lunch, saying she felt ill. She initially refused pleas from staff for her and her children, who she claimed had eaten the leftovers, to be admitted for treatment. None of their tests showed traces of death cap mushroom poisoning.

Patterson took the dehydrator to an E-waste site.

The dehydrator was recovered by the police and forensic examination of the appliance found her fingerprints and traces of the death cap mushrooms.
