A man has been put in prison after being convicted of murdering his mother.
The man is a convicted killer who was sentenced to life imprisonment in 2013.
His lawyer argued his client was mentally ill and his mother was in her late 80s.
It was the latest case of a mother being put in jail for her son’s crimes.
In the past year, more than 1,200 people have been sent to prison for child sexual abuse offences.
Criminal records and DNA were among the most common reasons given for their incarceration.
A recent review by the ABC’s Crimes in Custody program found the rate of prison-related arrests in the Northern Territory had fallen from 3.4 per cent in 2014-15 to 0.8 per cent last year.
The ABC’s Investigations program uncovered a number of cases of mothers and children being put to death in detention centres.
One of the most infamous cases involved a young girl from Brisbane who was convicted in 2014 of sexually abusing a 10-year-old boy.
She was given a life sentence and given the option to be transferred to another state or another country.
Another woman was sentenced in the Southern Territory to death after being found guilty of killing her 11-year old daughter in her sleep.
But it was the case of the mother who had been convicted of the murder of her mother, who was sent to jail for life, that sparked public outcry.
“What we are seeing in Australia is not just mothers, but mothers and daughters who are being put through the gauntlet to find their way out of jail and into society,” Ms Bishop said.
Police and the Department of Human Services are investigating the deaths of the three women.
