Erin Patterson, Australian woman at the centre of deadly mushroom meal, lashes out at media

The woman at the centre of the deadly mushroom lunch that left three guests dead and a fourth fighting for his life has lashed out at Australian media.

On July 29, Erin Patterson served beef Wellington pie to guests at her house, which included former parents-in-law Don and Gail Patterson, Gail's sister Heather Wilkinson along with Heather’s husband, Ian.

The Pattersons, both 70, died, along with Heather, aged 66. 

Heather's husband, 68-year-old Baptist church pastor Ian Wilkinson, survived, but was put in a coma for two months in hospital.

Erin Patterson’s ex-husband Simon Patterson was also invited however pulled out last minute after recovering from a mystery stomach illness that had put him in hospital for months.

Heather Wilkinson's partner Ian, was left fighting for his life in hospital for two months before he was discharged earlier this week. It means he could soon be able to speak about what happened on the day as police continue to investigate.

Erin Patterson was distressed and flustered as she was pressed by Australian journalists on Sunday outside her home in the eastern Victorian town of Leongatha.

"Erin, can we just ask you a couple of questions?" 7News asked. "No, go away!" she shouted.

Ian Wilkinson, who is a local church pastor, was discharged from hospital in what several people are describing as a miraculous survival.

A family statement thanked medical staff and the public after his release.

"The Wilkinson family would like to extend their heartfelt thanks to the Leongatha, Dandenong and Austin Hospitals for their unwavering dedication and exceptional care that played a pivotal role in Ian's recovery," the statement read.

"The medical team's expertise and compassion have been a source of comfort and hope throughout this journey."

Erin Patterson told police that the mushrooms used in the pie were a mixture of button mushrooms from the supermarket and dried mushrooms which she claimed she bought from an Asian supermarket in Melbourne months earlier.

It's believed the lunch was being held to attempt reconciliation between Erin Patterson and her estranged husband, Simon, the son of Gail and Don Patterson.

According to 7News, it is believed that Ian Wilkinson will help police with their inquiries.

The three deaths remain subject to a police investigation.
