The father, brother and sister of murdered man Matthew Fisher-Turner will be sentenced in the Supreme Court today.
Ernest Fisher, his son Joshua Fisher-Turner, and his daughter Hannah Fisher-Turner are all due to be sentenced in the Perth Supreme Court on Thursday morning, following the murder of 23-year-old Matthew Kyle Fisher-Turner.
In June a jury found the victim's father guilty of murdering his son during AFL Grand Final day in 2016.
The victim's brother and sister were also found guilty of accessory to murder after they helped to bury their brother's body in the backyard of their Parmelia home.

Ernest Fisher admitted to stabbing his son multiple times, claiming it was 'the right thing to do' and 'justified', because he held concerns his son was becoming increasingly violent.
Sentencing proceedings are due to get underway at 10am on Wednesday.
