A Melbourne woman who bludgeoned her great-aunt to death with a hammer has been sentenced to 18 years' prison.
Jessie Moore pleaded guilty to murdering greyhound trainer Karen Leek at Devon Meadows in May 2020.
Moore was living with Ms Leek when their relationship soured over Moore's drug use, and during an argument while the pair were watching Home and Away, she bludgeoned Ms Leek with a hammer.
An autopsy found she was struck at least a dozen times. Moore also covered Ms Leek's face with a plastic bag.
After the killing Moore took the hammer and some of Ms Leek's personal belongings, before going to KFC and buying cigarettes.
She bought a slushie on her way back to Ms Leek's property the following day and pretended she had discovered the body.
Moore was arrested and charged the day before giving birth to her second child.
In sentencing on Wednesday, Justice Paul Coghlan said Moore had an entirely dysfunctional upbringing, a history of drug use and a complex psychiatric history.
He said at the time of the murder her capacity to think clearly was impaired, reflecting her borderline personality disorder and borderline intellectual functioning.
But he said the attack had been brutal and sustained, on an unarmed victim who had been generous to her and had provided her with a home.
"The crime of murder is traumatic for victims, but when the crime occurs within a family it is particularly so," he said.
Moore will serve a non-parole period of 13 years.
