Erin Patterson GUILTY of murdering three relatives by serving them meal laced with death cap mushrooms

An Australian woman has been convicted of murdering three elderly relatives of her estranged husband with a meal laced with poisonous mushrooms, and attempting to murder a fourth, in a case that gripped the country.

Erin Patterson, 50, was charged with the murders of her mother-in-law Gail Patterson, father-in-law Donald Patterson and Gail’s sister, Heather Wilkinson, along with the attempted murder of Ian Wilkinson, Heather’s husband.

The four had gathered at Erin Patterson’s home in Leongatha, a town of about 6,000 people some 84 miles southeast of Melbourne, where the mother-of-two served them individual Beef Wellingtons that were later found to contain death cap mushrooms.

On Monday, the jury in the case found her guilty of all four charges.

She will be sentenced at a later date and faces a maximum life sentence. The 10-week trial in Morwell, a town around two hours east of Melbourne where Patterson had requested the case be heard, attracted huge global interest. Local and international media descended on Court 4 at the Latrobe Valley Magistrates’ Court the nearest court to Patterson’s home, despite being warned of lengthy delays.

State broadcaster ABC’s daily podcast on proceedings was consistently among the most popular in Australia during the trial, while several documentaries on the case are already in production.

The prosecution, led by barrister Nanette Rogers, told the court that Patterson had employed four major deceptions in order to murder her guests.

She first fabricated a cancer diagnosis to lure the guests to the lunch, poisoning their meals while serving herself an untainted portion, Ms Rogers told the court.

Patterson then lied that she was also sick from the food to avoid suspicion, before finally embarking on a cover-up when police began investigating the deaths, attempting to destroy evidence and lying to police, the prosecution said.

Patterson, who said during the trial she had inherited large sums of money from her mother and grandmother, retained a four-person legal team, led by Colin Mandy, one of Melbourne’s top criminal barristers.

She was the only witness in her defence, spending eight days on the stand, including five days of cross-examination.

Patterson told the court about a life-long struggle with her weight, an eating disorder and low self-esteem, frequently becoming emotional as she spoke about the impact of the lunch on the Patterson family and her two children.

She had lied about having cancer not to lure the guests to the lunch to kill them, but because she was looking for their help with telling her children and was embarrassed to say that she actually planned to have weight loss surgery, she told the court.

Patterson had also not become as sick as her lunch guests because she secretly binged on a cake brought by her mother-in-law and then purged herself, she told the court.

The jury of seven men and five women retired on June 30, taking a week to reach a verdict.

Justice Beale gave the jurors in the trial special dispensation to avoid jury duty for the next 15 years, due to the length and complexity of the case.
