A Murrumbateman woman has been charged with murder after allegedly shooting her partner in what police believe was a domestic violence incident on Monday night.
Dale Lee Vella, 52, who appeared in the Goulburn Local Court on Tuesday, did not apply for bail and was remanded in custody.
The victim has been confirmed as her partner, Mark Vella.
Ms Vella did not enter a plea to the murder charged when she made her court appearance on Tuesday via an audio visual link.
Magistrate Geraldine Beattie made an order for a forensic procedure.
She said samples and photos had already been taken by police with Ms Vella's consent.
Police prosecutor Sergeant Anthony Coleman said the forensic application included a swab of the accused's hands in relation to gunshot residue.
Defence solicitor Jacqueline Gore entered an application for her client to receive "urgent psychiatric and psychological assistance" in addition to medical assistance in relation to a previous cancer diagnosis.
Ms Vella will reappear at Goulburn Local Court on October 6, with a brief to be served.
Police and emergency services were called to the property on Murrumbateman Road, about one kilometre south-east of the township, about 10pm following reports a man had been shot.
"On arrival officers from Hume Police District found a 52-year-old man suffering a fatal gunshot wound," police said.
"A crime scene was established, which was examined by specialist forensic police.
"Detectives commenced an investigation into the circumstances surrounding the shooting.
"A 52-year-old woman was arrested at the scene and taken to Yass Police Station. Following inquiries, the woman was charged with murder."
A firearm was recovered at the scene and is undergoing ballistics testing.
The property where the incident occurred was in a rural subdivision area, with houses mostly built on small acreages.
Neighbours are distanced from each other on Murrumbateman Road, which runs for about 27 kilometers to the turn-off to Gundaroo.
Murrumbateman residents responded in near disbelief at the violence which had racked their "peaceful town" overnight.
A neighbour who lives across the road and around 200 metres from the crime scene, with a tall colourbond fence which screens his property from the road, said that he hadn't heard any gunshots but between 10pm and 10.30pm heard "a lot of sirens".
Two police four-wheel vehicles, one with detectives and other a uniformed officer from the local command, were at the crime scene on Tuesday and were searching through the garage.
