MUSHROOM DEATHS: 6 BOMBSHELLS UNCOVERED

Mum-of-two Erin has been charged after lunch killed three people

COMPUTER FILES SEARCHED

With Erin Patterson now facing murder charges over the alleged toxic mushroom meal in late July that left three people dead and one person in a coma, police say new computer evidence gathered from her Leongatha property will be at the forefront of their case.

Earlier this month, police descended on Erin's home in Gippsland, Victoria, and were captured retrieving bags of evidence.

Specialised "technology detector dogs", which are trained to sniff out SIM cards and USBs, were also deployed on the search.

A police source confirmed any deleted files on the 49-year-old's computer will be uncovered by the force's specialist team and may be used as evidence in court.

"It's not easy but it's doable on most occasions," he told the Herald Sun. "I would suggest they are looking for evidence of any searches she has made in regards to the type of mushrooms she's allegedly used and which ones would be most likely to have toxins."

The source also confirmed that the alleged killer's social media footprint will be investigated.

Erin has previously denied any wrongdoing.

PAST LIFE REVEALED

With her name now inextricably linked to the infamous July 29 meal, former colleagues of Erin's have spoken out about their experiences with the mushroom cook, revealing she once worked for the Department of Defence.

In early 2001, the mother-of-two began her career as an air traffic controller for Airservices Australia, where she was regarded as "something of a genius" by her peers.
