Two men have been told they should have contacted police about a woman’s alleged assault, rather than taking matters into their own hands and killing a man on Victoria’s Mornington Peninsula.

In the Supreme Court today, the pair, guilty of manslaughter, were sent to prison for at least seven-and-a-half and five years respectively.

Jade Goodwin, 39, was set upon by Brendan McDowall and Shane Heiberg in October 2017 after Heiberg was told Mr Goodwin sexually assaulted a woman.

McDowall was also told Mr Goodwin was holding another woman hostage in her own home. Neither allegation has been proven.

The duo arranged to go to the woman’s house to assault Mr Goodwin and wrestled him to the ground before Heiberg, who weighed more than 100 kilograms at the time, sat on him.

McDowall grabbed TV cables and a dog leash and put it around Mr Goodwin’s neck, which prosecutors argued ultimately caused his death.

The men admitted they killed Mr Goodwin, though they didn’t intend to, with McDowall telling detectives he was “going to give him a flogging”.

Justice Christopher Beale said McDowall should have let authorities handle concerns about Mr Goodwin.

“You should have contacted police, not taken matters into your own hands,” he said today.

The judge sentenced McDowall to 10 years and six months in prison with a non-parole period of seven years and six months, finding his offending was in the “mid-range” of seriousness.

Heiberg was sentenced to eight years in prison with a five-year non-parole period, with the judge finding that he played a lesser role in the death and has a greater prospect of rehabilitation.

Justice Beale said he was confident the pair felt remorse.

Both also had time shaved off their sentences for pleading guilty to manslaughter at the first available opportunity.

After Mr Goodwin’s death, McDowall and Heiberg wrapped his body in a doona and dumped it in a shallow grave at Tyabb before covering it with concrete and soil.

It was discovered later the same day.
