Erin Patterson: Former inmate’s bombshell claim about food tampering inside Dame Phyllis Frost Centre

A former inmate at Melbourne’s maximum security women’s prison has shared shocking new details about the food tampering allegations against triple murderer Erin Patterson.

The inmate, who remains anonymous, kept a diary while she was locked up at the Dame Phyllis Frost Centre, where she wrote about different incidents within the prison.

Patterson, who was found guilty of murdering three family members and attempting to murder another, was accused of tampering with another inmate’s food while awaiting trial.

The bombshell accusations were allegedly made by inmates at the Melbourne prison, but could not be made public until after the trial concluded.

A former inmate told news.com.au she heard about the food tampering incident when she asked a fellow prisoner if she could borrow her mayonnaise.

“She just laughed and joked about me ‘poisoning it like Erin Patterson did’,” the former inmate said.

“I was like ‘What the f***?’ and she told me the story about how prison officers found mayonnaise in Erin’s room that was allegedly used to poison (one of the inmates).

“She went to medical and was vomiting everywhere. She was saying that the mushroom lady’s cell was searched and they found chemistry books with pages tagged including sections on natural remedies.

“This was all part of the investigation into the poisoning (of the inmate).”

The former inmate revealed that Patterson was moved to the Gordon unit while the investigation for poisoning took place.

According to her diary entry, prison guards found “two bottles of mayonnaise in Erin’s clothes basket” during a search of her cell.

While a justice department spokesperson said there was “no evidence to support that there has been any contaminated food or suspected poisonings,” the former inmate believes the incident “100 per cent happened.”
