Triple murderer Erin Patterson protested about the conditions of the jail cell she was kept in during her trial.

Patterson, 50, was on Monday found guilty of three counts of murder and one count of attempted murder over the deadly mushroom lunch at her home in Leongatha, Victoria, in July 2023.

Now details that emerged during her trial, but could not be previously reported, can finally be revealed.

During the early stages of the trial, Patterson’s defence team made an impassioned plea to Justice Christopher Beale about the conditions of her “cold” cell that made it difficult for her to sleep.

In the wake of her November 2023 arrest, Patterson has predominantly been housed at Dame Phyllis Frost Centre — a maximum security prison in Melbourne’s western suburbs.

But throughout the course of her Supreme Court hearing, Patterson spent weeknights inside the cells at Morwell Police Station to allow her to be closer to Latrobe Valley Magistrates Court.

In the first week of the trial, defence barrister Colin Mandy SC told the court Patterson had been cold throughout the night because she did not have a doona or a pillow.

He also said she had not received a computer that she had requested to assist her with the case.

“This brief is massive and she has a good understanding of it, but she needs to have access to it ­because she’s providing us with instructions about various things as we go,” Mandy said.

“She had an agreement with Corrections about the things that she would be permitted to take into her cell, and last night, for whatever reason, that wasn’t the case.

“She didn’t have access to her brief, she didn’t have access to writing materials.

“She’d agreed with Corrections that she could have a doona and a pillow, and she wasn’t given those things.

“At some stage she was given a blanket, but she spent the night cold — and awake because she was cold, and she can’t operate like that.”

Mandy said Patterson required “special” treatment to be able to give legal instructions to her defence team.

“It is our submission that someone who is in police cells for five weeks, facing a murder trial, with a massive — several murder trials — with a massive brief of ­evidence, should be afforded some accommodation because, in some ways, she does deserve special – not deserve, but she requires ­special treatment so that we can do our job properly,” he said.

Throughout the trial, journalists were banned from reporting on the fact Patterson was being kept in custody to prevent prejudicing members of the jury.

Rather than face Melbourne Supreme Court, Patterson had requested to shift her trial to her local Gippsland region — a move which saw the hearing delayed by months.

Patterson was transported from Melbourne to Morwell early on Monday and driven back to Melbourne on Friday afternoon for the duration of her 10-week trial.

Patterson will in August be sentenced for the murders of Don Patterson, Gail Patterson and Heather Wilkinson, and the attempted murder of Ian Wilkinson.

She has been taken back to Dame Phyllis Frost Centre, where she could spend the rest of her life serving out her sentence.
