A Melbourne man allegedly wrote a note saying he killed his youngest sister to get "justice" after they fought about money.
Ning Wang is charged with murdering his 57-year-old sister who was visiting from China.
The 70-year-old allegedly bashed his sister Qin Wang and put her in the boot of his car before driving to his other sister's home in February 2019, court documents reveal.
"I killed my sister at 7am to achieve my justice," the accused allegedly wrote in a note found at the Clayton South crime scene.
Wang and his sister argued about money, the care of their elderly father and his desire to go to Taiwan before the fight escalated.
He's accused of attacking, then dragging her body to a car, putting it in the boot and covering it with a blanket.
Wang drove to another sister's house at Burwood East and attacked his nephew with a metal bar, police say. They have also charged him with recklessly causing injury.
"I don't want to live, I'll fight you to the death, I killed her, she's in the boot," Wang said, according to a police summary.
There had been an ongoing dispute with Wang and his other sisters over money and costs related to the care of their father, the court documents show.
The dead woman was left with serious injuries including fractured ribs, a broken eye socket and bruising.
Defence Senior Counsel barrister Peter Morrissey argued a charge of manslaughter should be considered rather than murder.
He told the court there was no dispute about a fight, but that Ms Wang died not from her injuries but because of an "occluded airway" after she was left in a vulnerable position.
Mr Morrissey also produced evidence from China showing the 57-year-old had been diagnosed with asthma prior to her death.
An exact cause of death was not determined but was likely to be strangulation or suffocation, pathologist Dr Melanie Archer said.
Wang has pleaded not guilty to both charges and was directed to stand trial in the Supreme Court.
He will face a directions hearing on Friday.
