Overview
- The Supreme Court of Victoria imposed life imprisonment with a 33-year non‑parole period for the 2023 poisoning deaths of three relatives and the attempted murder of a fourth.
- Justice Christopher Beale said the crimes showed substantial planning and a lack of remorse, rejecting Patterson’s account of an accidental contamination.
- A jury in July found Patterson guilty of murdering Don and Gail Patterson and Heather Wilkinson, and of attempting to kill Ian Wilkinson, who survived with serious aftereffects.
- The sentence was televised in a rare move for the court as the case drew intense national and international media attention.
- Patterson was returned to Dame Phyllis Frost Prison and is expected to remain separated from other inmates for her protection; prosecutors had sought no parole and she has 28 days to appeal.
