Stabbing her long-term lover seven times in the back with a peeling knife was an "utterly irrational response" to seeing him with his wife, a judge told Gloria Cherrington yesterday.
Justice Christian Whata sentenced Cherrington, 51, a caregiver, to six years and one month's prison for attempted murder on August 27 last year, which she had previously admitted.
In the High Court at Dunedin, Justice Whata imposed no minimum period of imprisonment. She was given a first warning under the "three strikes" legislation.
Justice Whata said upon seeing the man and his wife walking in South Dunedin, Cherrington reached a "tipping point" into extreme violence, for which she had not previously shown much propensity.
Cherrington had an "emotional fragility" and an alcohol abuse problem, in the context of a long and turbulent relationship with the victim. She had felt as though she was treated as a "part-time partner" by the man for whom she had relocated from Auckland to Dunedin.
