Son who killed mother for money gets 20 years

This report from the   website is a chilling reminder of how euthanasia & assisted suicide could aid and abet someone in the killing of a relative for financial gain. And who would ever know?AdelaideNow
AN autistic Perth man who murdered his mother may never be released and her body might never be found, a court has heard.
Brent Donald Mack, 28, was on Friday sentenced by Justice John McKechnie to life in prison with a minimum of 20 years for murdering Ah Bee Mack, who also went by the name of Pauline, between December 18 and 29, 2008.
Mack, who has been in custody since August 2010 and was found guilty in November last year, claimed in a police interview that his mother had committed suicide.
He told police he had found his mother in the shower with self-inflicted knife wounds to her wrists and that she had asked him not to tell anyone.
During the trial, the court heard Mack left her in the shower for a week with the cold water running.
How Ms Mack died remains unknown as her body has not been found. Mack directed police to Lake Gwelup in Perth's northern suburbs, but extensive searches proved fruitless.
Justice McKechnie, who presided over the trial without a jury, on Friday said Mack killed his mother for her money and property, stealing more than $225,000.
Mack constructed a web of lies to hide his crime, the court heard, telling people she was living with someone else and sending fake cards and letters that he had signed with his mother's name.
Referring to previous fraud and stealing offences, Justice McKechnie said Mack had a lengthy record of dishonesty.
"You are a dishonest, devious individual,'' he said.
The lies showed Mack had a degree of callousness and was aware his actions were wrong, Justice McKechnie said.
He said Mack was a very damaged young man whose autism did not explain the crime, let alone excuse it.
"There was no causal link between the autism and the offence,'' Justice McKechnie said.
He said Mack deliberately murdered his mother for financial gain and may never be released, depending on the disposition of the government of the day.
The Department of Corrective Services would have to devise a comprehensive management plan for Mack, who was vulnerable to bullying and maltreatment in jail, Justice McKechnie said.
Whether Mack accepted psychiatric treatment was another matter, he added.
Prosecutor Dave Dempster described the crime as ``a remorseless and planned matricide''.
Mack stood in the dock and kept his head down with his eyes tightly closed during the proceedings, as he has done during most of his trial and other court appearances.
No family member was present to support him.
