An Adelaide woman and her lover will spend more than 20 years behind bars for the murder of her husband Steven Hinrichsen in 2018.
Tanya Hinrichsen conspired to murder her husband and has been handed a 22-year non-parole period in the Supreme Court.
Justice Sophie David said her lover Gavin Scott Skinner stabbed the man more than 50 times and will spend at least 24 years in prison.
A third man, Robert John Thrupp, will remain in jail for at least seven years after he was found guilty of manslaughter.
Mr Hinrichsen, who used a wheelchair, was found stabbed to death at his Morphett Vale home in December 2018.
During sentencing submissions earlier this month, the Supreme Court heard the murder of the 63-year-old grandfather was carried out with an "extreme level of violence".
'Egregious abuse' of trust
Justice Sophie David today said Hinrichsen had become increasingly resentful of her husband and viewed him as an impediment to her new relationship with Skinner.
She said that, "incredibly", Hinrichsen had wanted the victim to agree to letting Skinner stay at their house some nights a week.
A text message sent from Skinner to Tanya Hinrichsen said: "I'm so ready to go on a hunting spree."
She replied: "If it's to do him then I'll give you my permission."
The court heard Skinner and Thrupp went to the home, and that Skinner attacked Steven Hinrichsen, causing 50 wounds to his head and body.
A photograph was smashed over his head and the knife was dumped behind the stove.
Mr Hinrichsen had been confined to a wheelchair through various ailments.
Justice David said she accepted Tanya Hinrichsen was not present at the time of the killing and did not anticipate the level of violence.
But she said that she had murdered the father of their children, and "must now live with the consequences of your conduct".
"Your offending and conduct, in intentionally encouraging Gavin Skinner to murder the deceased, was an egregious abuse of your husband's trust," she said.
"He was a vulnerable man, incapacitated and confined to a wheelchair, yet you encouraged another to murder him for your own selfish purposes.
"It is difficult to comprehend your motivation to commit this offence. It was open to you to simply leave your husband."
'Nothing less than frenzied'
In sentencing Hinrichsen's co-accused, Justice David said Skinner had "inflicted a brutal attack on a vulnerable man for your own selfish purposes".
"This was nothing less than a frenzied attack," she said.
"It was completely unjustified and gratuitous."
On Thrupp, Justice David said that he was "present in the deceased's home" when Skinner inflicted the fatal wounds.
"You knew the deceased was vulnerable and incapacitated, and Gavin Skinner held much animosity towards him, and had assaulted him on one previous occasion," Justice David said.
"While you did not physically inflict any of the wounds or injuries to the deceased, you were in sufficient proximity to see what had taken place.
"When interviewed by police later that day, you denied having attended at the deceased's home with Gavin Skinner.
"It is difficult in those circumstances to give any weight to the expressions of remorse made by you to a psychologist or on your behalf by counsel."
Outside court, Mr Hinrichsen's daughters and sister said they welcomed the verdicts and justice had been served.
One of Tanya Hinrichsen's daughters said it was unimaginable a mother would do such a thing.
"I'm so glad she's got life," she said outside court.
"I was shocked when it happened – I would never think she would do something like that."
Another daughter said it was a scary experience to go through.
"I was happy when I found out how long [Tanya Hinrichsen] got, and all the other people too," she said.
"I don't want anything to do with her."
Mr Hinrichsen's sister Sandra McIntyre said the killing was incomprehensible and she still has nightmares about it.
"We're all basically pleased with the outcome, they got what they deserved," she said.
"But if I had my way I'd lock them up and throw away the key.
"The law is the law and we must respect that, and I'd like to thank the wonderful detectives, the prosecutor, and our [SAPOL] liaison officer."
