A 47-year-old woman was stabbed to death during a domestic clash inside her Brooklyn home late Sunday – and her son was hurt as he stepped in to help his dying mom, authorities said.
Antoinette Stewart-Gordon was knifed in the neck and stomach during the vicious attack around 9:30 p.m. inside the home on East 81st Street near Flatlands Avenue in Canarsie, cops said.
Her 15-year-old son tried to intervene, and ended up with a slash wound to his hand, police said.

Both victims were taken to Brookdale University Medical Center, where Stewart-Gordon succumbed to her injuries, cops said.
The teen boy was listed in stable condition.
Police described the murder as a domestic incident, and said a male suspect fled the scene.
His exact relationship to the family is unknown.
