Narrative

Justice Stephen McLeish set aside the 33-year non-parole period previously imposed on Patterson, ruling that the seriousness of her crimes meant she should never be eligible for release. “The applicant’s intent to murder all four victims was sustained for nearly three weeks from when she invited them to lunch, through to preparing and serving the poisoned meal and then throughout the protracted suffering and ultimate deaths that resulted,” he said.
