A South Australian man who beat his partner to death has been sentenced to life in prison with a non-parole period of 20 years.
Bradley Wayne Trussell, 30, was found guilty of murdering his 25-year old girlfriend Eden Kennett at Mount Gambier three years ago.
The Supreme Court heard Trussell "smoked a cone" while his girlfriend was convulsing on the kitchen floor after the beating before giving her a cold shower and driving her to his sister's house while she was unconscious.
She was then taken to hospital, where she died.
Justice Anne Bampton acknowledged the "unrelenting grief and anguish" of those who loved Ms Kennett and valued her life.
She rejected defence submissions that the offending was at the lower end of the scale for murder, and declined to set a non-parole period below the mandatory minimum 20 years.
Justice Bampton said the relationship was "dysfunctional, unstable and domestically violent and marked by mutual drug use".
The court heard Trussell had a "short fuse" and became angry when he woke up in the early hours of the morning to find Ms Kennett using his mobile phone.
Ms Kennett's mother, Tammy Simpson, told the media Trussell had taken her daughter's own phone away.
Ms Simpson sobbed throughout the hearing.
Trussell showed no emotion.
The court heard Trussell had a traumatic childhood in which he lived in constant fear of his violent and alcoholic father.
The court heard his father wanted to "toughen up" Trussell by being physically violent towards him and Trussell developed an anti-social personality disorder as well as drug and alcohol issues.
Trussell is appealing against his murder conviction and his defence lawyer successfully applied for part of the sentencing remarks to be suppressed to prevent prejudice to any further hearings.
'Don't be a statistic', says victim's mum
Speaking outside court, an emotional Ms Simpson said Eden was "bubbly, bright, energetic, loud" and "really happy a lot of the time".
"She just wanted to be loved and wanted to love someone," she said.
Ms Simpson said Ms Kennett "kept leaving" Trussell but "kept going back", and urged people to "stand up and speak out" about domestic violence.
"Don't be a statistic," she said.
"Because she's 67 as far as the government knows, but her name is Eden Kennett.
Ms Simpson said no sentence "would ever fix it".
"Eden's not coming home," she said.
