Erin Patterson has finished giving evidence in her triple murder trial, bringing an end to eight days of testimony in the Victorian supreme court.

Patterson answered “disagree” to three final questions from prosecutor Nanette Rogers SC on Thursday morning: that she deliberately sourced death caps in 2023, included them in beef wellingtons served to her lunch guests, and intended to kill them when she did so.

Prosecutor Nanette Rogers SC turns to evidence about factory resets performed on the mobile referred to as “Phone B”.

The court previously heard four resets – one in February 2023 and three in August 2023 – were performed on the phone that Erin Patterson provided to police during the search on 5 August 2023.

Rogers says one of these resets were done when she was left alone to call a lawyer while police searched Patterson’s Leongatha home.

Patterson rejects this and says she phoned a lawyer at 2pm.

Rogers says Patterson performed the three factory resets after the lunch to “conceal” the contents on Phone B.

Patterson rejects this.

Rogers then turns to her final points in the cross-examination.

She suggests Patterson deliberately sourced death cap mushrooms in 2023.

Patterson rejects this.

Rogers says Patterson deliberately included death cap mushrooms in the beef wellingtons she served her lunch guests.
