As his father lay gasping on the floor with a broken jaw, Nathan Missen did not help him but instead put a towel over his head and repeatedly stomped on him in a fatal attack.
Missen, 29, has been jailed for 21 years for murdering his father, Mark Missen, at their Mooroopna home in January 2016, before dumping his body in an old mineshaft days later.
Supreme Court Justice Jane Dixon recounted the violent scene as she sentenced Missen yesterday, calling it a murder of ‘‘appalling brutality’’.
She said after bashing his father, Missen asked his girlfriend Ebonee Rohde to get something to stop the bleeding, and she returned with a towel and a pillow case.
‘‘You said to Rohde, ‘It’s too late to get him some help, I’ve broken his jaw’,’’ Justice Dixon said.
‘‘You wrapped (the items) around your father’s head and then kicked and stomped on him repeatedly whilst yelling at him to be quiet.’’
Missen then wrapped a belt around his father’s neck and pulled it tight, before stashing the body in a cupboard and cleaning the blood from the carpet.
Three days later, Missen, with the help of Rohde and a friend, dumped the body, which was discovered a month later in an old goldmine at Whroo.
The body was so badly decomposed that forensic police could only identify Mr Missen from his fingerprints.
While other family members filed a missing person’s report, Missen and his girlfriend sold Mr Missen’s belongings on Gumtree.
The killer and Rohde had recently moved into a home with Mr Missen, 56, and it had been intended as a ‘‘fresh start’’ for the trio.
But Missen had deep-seated emotional problems linked to a troubled childhood, and would often row with his father.
Missen said the argument on the day of the murder had centred on a car the pair had been fixing together.
His father gave the car away and Missen believed he did so to ‘‘spite him’’.
But the judge said the fight was also likely about Missen’s treatment of Rohde.
The father and son had a turbulent but close, even ‘‘co-dependant’’ relationship, Justice Dixon said.
‘‘You have said with hindsight that you felt you could not live with your father, but you also could not live without him,’’ she said.
‘‘Tragically, as a result of your own criminal actions, you will now have to survive without your father’s love and support.’’
Missen, who pleaded guilty to murder, stood emotionless in the dock as he was sentenced to 21 years in jail with a minimum term of 17 years.
In passing sentence, Justice Dixon took into account Missen’s battle with testicular cancer while in custody as well as the physical and emotional abuse he suffered during childhood.
