A woman obsessed with knives and death who killed a teacher and tried to murder her mother is on release from jail despite telling police she wants to murder more people.

Debbie Marie Adams, who spent 13 years in prison for manslaughter, is free on a community corrections order that was imposed after she threatened to kill two support workers.

Having served her prison sentence for manslaughter, Adams was released into the care of mental health services.

In 2024, Adams, now aged 43, suffered a mental health episode and was taken to Wyong Hospital.

She was assessed and released into the care of support workers Brooke Honeyman and Jarrod Kosorukow, but said: 'I want to kill those c***s.'

A witness said Adams had said: 'I haven't done it already because I couldn't find anything to do it with, but I'll do it, I'll find something to get one of them when I get home. I've killed someone before, I'll do it again.'

Having been arrested for the threats, Adams told police: 'I was born to kill and I'll kill again.'

In January 1999, Adams, who was aged just 16 at the time, attempted to kill her mother by stabbing her in the neck with a bread knife while screaming: 'I'm gonna kill ya, I'm gonna kill ya.'

While in Yasmar Detention Centre in western Sydney for that killing, Adams viciously killed teacher's assistant Scott Bremner, 33, on July 23 that year.

Adams had been in a cooking class when given a box that contained an apron and a large kitchen knife.

Mr Bremner, a storeman at TAFE, was filling in as a temporary teacher's aide that morning. He was unaware of Adams' background and did not know she had become excitable when handed her toolbox 

Despite fears about Adams' prior behaviour, and her obsession with knives and sharp objects, and a staff member's fear that the cooking equipment 'looked like killing knives', no one warned Mr Bremner of the risk. 

When the class was being taught how to cut vegetables, Adams walked behind Mr Bremner, raised the knife in both hands above her head and stabbed him in the back.

He died on the operating table at Royal Prince Alfred Hospital.

After Adams was detained, she raved to a youth worker, 'Do you think he felt it? Do you think it hurt? Good job, eh, good job. It wasn't even supposed to be him. It was supposed to be someone else but he was there.'

A judge later found Adams 'had a pathological fascination for knives' and was in 'a highly aroused state' after being handed her kitchen box.
