Two state MPs are demanding a swift review after NSW Police failed to respond promptly to a triple-0 call reporting screams from a home.

An hour after the call, a dying woman was discovered, leading to shock in the Northern Rivers community.

This is the third fatal domestic violence case in the Richmond Police District this year, involving an alleged killing by a male partner.

A critical incident investigation has been initiated to examine the delayed police response.

The rise in domestic violence killings has raised concerns about the perpetrator's history with police and bail status.

New coercive control laws are set to be implemented to protect domestic violence victims.

The community is demanding swift and independent investigations into such incidents.

The NSW Police Force and Government are emphasizing the seriousness of domestic violence, with oversight from relevant authorities.
