A SON who admitted to stabbing his mother in a frenzied attack will be sentenced next year.

Bradley Mottram faces a maximum penalty of life behind bars for the murder of his mother, Simone Mottram, in Inverell more than two years ago.

Mottram, now aged 21, appeared in the NSW Supreme Court in Sydney on Friday for an arraignment where he formally pleaded guilty to the murder.

Justice Peter Johnson heard charges of unlicenced driving, stealing his mother's car and negligent driving were being placed on a form one certificate, meaning they will be taken into account in sentencing.

Mottram made no application for bail and it was formally refused by Justice Johnson who adjourned the case for a sentencing hearing in April, next year.

Mottram has been in custody since the October 19, 2015, stabbing murder inside Ms Mottram’s Froude St house in Inverell.

In early-October, The Leader revealed Mottram had pleaded guilty to murder and had made repeated admissions to witnesses after he crashed his mother’s Hyundai Getz on Copeton Dam Rd, out of Inverell. 

"I killed her. She's dead," he screamed at three witnesses on the road about 2.30pm, which was detailed in draft facts tendered on his plea in the local court. 

"She's dead. I've murdered her."

The draft document stated the then 19-year-old drank a can of rum and scribbled several notes as witnesses called police, repeating his admissions "continuously about 40 times" to three people at the scene.

The ***** is dead. I've killed her. I'm a murderer. The ***** is dead.

Bradley Mottram said in draft facts

"The ***** is dead. I've killed her. I'm a murderer. The ***** is dead," draft facts stated.

In the note police seized from the scene, Mottram said "this was not planned. I was drunk, it was an accident. Holy s***, I'm sorry".

A 10-volume brief of evidence detailing the murder and relationship between Mottram and his mother was tendered to the court, detailing a history of mental health and drug and alcohol abuse.

According to the court documents, Mottram was alone with his mother from 11.30am and “during this time the deceased said something to the accused which made him snap”.
