Overview

• A Supreme Court jury on July 7 convicted Patterson of three counts of murder and one count of attempted murder after a nine-week trial in Morwell.
• The poisoned beef Wellington lunch in July 2023 killed her parents-in-law, Don and Gail Patterson, and Gail’s sister Heather Wilkinson; Ian Wilkinson survived following weeks in hospital.
• Prosecutors relied on mobile phone tower data, iNaturalist foraging records, digital device forensics and residue tests from a discarded dehydrator to prove deliberate poisoning.
• Patterson admitted fabricating a cancer diagnosis, faking illness after the lunch and falsely denying ownership of the dehydrator to investigators.
• She will be sentenced later this year and faces up to life imprisonment under Victoria’s sentencing guidelines, with a 28-day window to lodge an appeal.
