A 40-year-old Miramichi man has been charged with second-degree murder in the death of his mother on Tuesday.
Christian Jason Godin is accused of killing Marie Geraldine Godin, 62, who was attacked inside her home and later died.
Police have said the victim and accused are related.
The victims' sister, who was in court on Wednesday, confirmed Godin is the victim's son.
Godin will be sent for a psychiatric assessment to determine if he is fit to stand trial and if he is criminally responsible for the allegations against him.
Defence lawyer Melanie McAuley told Judge Geri Anne Mahoney she had difficulty communicating with Godin. She wasn't sure he understood the seriousness of the charge, she said. As a result, she requested the assessment.
Godin will return to court on May 8.
Police say they were called to a residence on Hanover Street shortly before 9 p.m. about a woman being attacked.
The victim was transported by ambulance to the Miramichi Regional Hospital, where she was pronounced dead a short time later, said Cpl. Tony Porter.
He declined to discuss the nature of the attack or what, if any weapons, were involving, citing the ongoing investigation.
He also declined to say who called police.
The suspect was arrested a short distance from the red brick apartment building where the attack occurred and was taken into custody without incident, said Porter.
"Information received to the responding units led to the arrest of that male," he said without elaborating.
Porter also declined to say whether the victim and the suspect were known to police.
"The Miramichi Police Force are considering this an isolated incident, so there’s no danger to the general public in any way," said Porter.
Neighbours told CBC News they are shocked by the incident.
They described the victim as being a very nice lady.
One man, who lives in the apartment above the victim's, said he didn't hear anything unusual on Tuesday night.
Police will execute warrants at the victim's first-floor apartment and search for evidence with the assistance of the RCMP's forensic identification section from Bathurst.
One police officer was guarding the scene in a black, unmarked car on Wednesday afternoon.
An autopsy will be performed in Saint John.
The investigation continues.
