Duncan was in a front lounge room when a bullet hit her.
Police do not believe she was the target of the shooting.
Paramedics tried for about an hour to save her, but she died at the scene.
One of the victim’s neighbours told 9News Duncan’s 34-year-old son Shaine arrived at the scene as people were shooting at his home.

“He was down the road at a friend’s house, and as he got closer to his house, he saw the people there shooting the house,” witness Shaun said.
“As we come outside, we just hear the son yelling, ‘My mum’s been shot.’
“He was pretty upset, devastated.
“And then her daughter turned up a bit later and she was a mess.”
Three men were seen in the area at the time on CCTV footage.
Shaine’s 21-year-old partner was also in the home at the time but was uninjured.
A 32-year-old and a 19-year-old man were arrested at homes in Liverpool and Belmore yesterday.
Both have been charged with murder, refused bail and will appear before Bankstown Local Court today.
