Australian True Crime: The Death Cap Murders
Netflix is set to release an intriguing new documentary series, “Death Cap: The Mushroom Murders,” on 16 December 2024. This series delves into the high-profile case of Erin Patterson, an Australian woman who was convicted of a grisly crime that left her family and the wider community in shock.
The Crime
On 29 July 2023, Patterson invited her estranged husband’s parents, Don and Gail Patterson, as well as their daughter-in-law Heather Wilkinson and her husband Ian, to a luncheon at her home in Leongatha, Victoria. Unbeknownst to the family members, the beef Wellingtons they were served contained deadly death cap mushrooms.
After consuming the meal, all four guests fell ill with suspected gastroenteritis. Despite her own symptoms, Patterson refused hospitalization and was only admitted 24 hours later when she voluntarily returned.
Tragically, Gail and Heather died in the hospital within days, while Don passed away a day later following a liver transplant. Ian survived but faced months of recovery.
Dr. Chris Webster, who treated the victims, revealed that he suspected Patterson’s guilt almost immediately: “I knew.
I thought, ‘Okay, yep, you did it, you heinous individual. You’ve poisoned them all.'” His suspicions were further confirmed when Patterson claimed she bought the mushrooms from Woolworths, a statement that added to the mystery and suspicion surrounding the case.
A True Crime Enthusiast
Erin Patterson’s background as a true crime enthusiast added an unusual twist to the case. She was known for her active involvement in Facebook groups dedicated to uncovering crimes, including Keli Lane, who had been convicted of murdering her newborn baby. This reputation turned against her when the truth emerged.
Ruth Dubois, daughter of Ian and Heather Wilkinson, shared her concerns about the intense media coverage: “The intense media coverage has left me second-guessing every word I say, worried about who I can trust with my thoughts and feelings. It has changed the way I interact with people.” Similarly, Ian Wilkinson highlighted the societal shortcomings that showered so much attention on those who commit crimes, rather than recognizing the good deeds of others.
The Verdict
Patterson was arrested on 2 November 2023 and charged with three counts of murder and five counts of attempted murder. She was tried in April 2025 before a jury in the Supreme Court of Victoria, where she denied poisoning her family members and pleaded not guilty to all charges. After hearing victim impact statements from relatives, Justice Beale sentenced Patterson to three consecutive life sentences plus 25 years of imprisonment.
Patterson is currently serving her sentence at the Dame Phyllis Frost Centre in Melbourne and will become eligible for parole in 2056, when she will be 81 years old. The case remains a notable chapter in Australian criminal history, with Patterson’s appeal against her convictions officially filed in November 2025.
The release of “Death Cap: The Mushroom Murders” on Netflix is set to provide viewers with an in-depth look at this bizarre and tragic event, blending true crime intrigue with the mystery surrounding the method of murder.
