Erin Patterson mushroom murder trial LIVE updates: Accused killer’s list of purchases at a service station a day after deadly lunch is revealed to jury

Detective Senior Constable Khuong Tran told the court on Tuesday he obtained CCTV footage from the Caldermeade BP on July 30, 2023 – a day after the lunch.

The CCTV, which was played to the jury, depicted Erin Patterson, wearing a grey cotton jumper, white pants and carrying a handbag, pull up out the front of the service station in her red MG at 3.20pm.

A still image showed Patterson entering a toilet inside the servo for nine seconds before exiting and browsing the store.

Patterson was shown going to the food section and having a look around before grabbing an item.

The jury heard she headed to the drinks section in another aisle before paying for her items and leaving.

The items purchased were a type of sour confectionary, a ham, cheese and tomato sandwich, and a sweet chilli chicken wrap, the court heard.

The edited two minute and 34 second CCTV vision along with 11 stills were exhibited.

The court heard earlier in the trial Patterson told hospital staff she had vomiting and diarhhoea in the days following the lunch.

Telecommunications expert Dr Matthew Sorell (pictured) was put under the pump by lead defence barrister Colin Mandy SC on Tuesday.

Mr Mandy attempted to cast doubt on Dr Sorell’s belief Patterson’s phone was detected in two death cap mushroom Gippsland hotspots at Outtrim and Loch.

Victoria Police Cybercrime Squad senior digital forensics officer Shamen Fox-Henry (pictured below) has explained to the jury how he conducts forensic investigations on computers, mobile phones and other devices.

Patterson, who is wearing a black and white striped top, listened as Mr Fox-Henry explained how he uses specialised Victorian Police digital investigation software to ‘examine and determine’ the data.

Mr Fox-Henry told the jury he has conducted data recoveries and extraction from computer and mobile phone systems after joining the Cybercrime Squad in July 2023.

The court was shown a short powerpoint titled ‘digital forensics’ which was prepared by Mr Fox-Henry.

Mr Fox-Henry explained he extracts data from a device hard drive and sends it back to the police investigator as a ‘portable case’.

He said he takes the data and puts the information into ‘human readable form’.

Mr Fox-Henry agreed investigators can view files, images and other data contained in the portable case.

He also said he can find internet search downloads also known as ‘artefacts’.

Erin Patterson, 50, is accused of murdering her in-laws, Don and Gail Patterson, and Gail’s sister, Heather Wilkinson, after allegedly serving them a beef Wellington lunch with death cap mushrooms.

Patterson is also accused of attempting to murder Heather’s husband, pastor Ian Wilkinson, who survived the lunch after spending several weeks in an intensive care unit.

The court heard Patterson’s estranged husband, Simon, was also invited, but didn’t attend.

Witnesses told the jury Patterson ate her serving from a smaller and differently coloured plate than those of her guests, who ate from four grey plates.

Patterson told authorities she bought dried mushrooms from an unnamed Asian store in the Monash area of Melbourne, but health inspectors could find no evidence of this.

The health department declared the death cap poisoning was ‘isolated’ to Patterson’s deadly lunch.

Multiple witnesses, including Simon Patterson, Ian Wilkinson and other family members, have given emotion-charged evidence to the jury.

Medical staff have told the jury of the painful symptoms the dying lunch guests and Ian Wilkinson suffered.

An expert witness told the court death cap mushrooms were detected in debris taken from a dehydrater Patterson had dumped at a local tip.

Telecommunications expert Dr Matthew Sorell also told the jury Patterson’s phone was detected near areas in Outtrim and Loch where death cap mushrooms had been spotted.

CCTV of a short toilet pitstop at a Gippsland BP service station following the day of the lunch was also shown to the court.
