'Nobody cared or fought like she did'

MICHELLE Reynolds fought for her life on the morning of April 4, 2016.

The mother of six was found dead with stab wounds to her neck - and to her hands, after trying to save herself from an enraged partner.

That Wayne Ashley O'Sullivan, now 50, was responsible for the 46-year-old's murder was never in doubt.

Why he chose to stab Ms Reynolds that morning in Rosewood was less explicable.

But for Jack Reynolds, Michelle's eldest son, there is no excuse, no closure, no forgiveness.

"I do not care for your apology. And I do not care for your ignorant, self-appointed right to forgiveness and I never will," Mr Reynolds told the murderer sitting in Brisbane Supreme Court dock on Monday morning.

"The pain has endured the test of time.

"Nobody cared or fought like she did."

He described his mother as his "lighthouse".

Prosecutor Vicki Loury said Ms Reynolds was killed after refusing to kiss O'Sullivan one morning.

He went to his caravan, took a knife from a tackle box, returned to the room and severed her carotid artery and jugular.

Neighbours heard screaming at the John St home early that morning.

O'Sullivan then drove to an aunt's house in Leichhardt and sat down without speaking.

Eventually he told his aunt she might want to call an ambulance.

O'Sullivan then walked off and police later found him at an oval.

"I think you're looking for me," he said.

The court heard the father of five was estranged from his own children and had just learned he had to double his child support payments.

"There was some pressure on him to cope with financial circumstances," defence counsel Simone Bain said.

O'Sullivan was probably suffering some type of depressive or adjustment disorder "but nothing to justify or excuse" his behaviour, Ms Bain added.

Justice David Boddice said unusually for a domestic murder case, there'd been no history of violence between the couple.

But the couple had started "regularly arguing" in the days before April 4.

The judge accepted O'Sullivan assisted the police investigation and was remorseful.

O'Sullivan pleaded guilty and was sentenced to life in prison.

Murder convictions carry a minimum 20-year non-parole period.

His 973 days in custody counted as time served so O'Sullivan can expect at least 17 more years in custody.

"You will have to live with the consequences," Justice Boddice said.

"Your regrets will be cold comfort to the family of your partner."  -NewsRegional
