A Mount Gambier man who beat his partner to death has been sentenced to life in prison with a non-parole period of 20 years.

Earlier this year in the Supreme Court Bradley Wayne Trussell was found guilty of bashing 25-year-old Eden Kennett to death in December 2018. He was sentenced last week.

The Supreme Court heard Trussell had smoked cannabis while Ms Kennett was convulsing on the kitchen floor after the attack, 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.

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.
