A woman’s body has been found in a home in NSW with police charging her son with murder.

Emergency services were called to a home on Merrigum St in Windale, Lake Macquarie, just after 8pm on Saturday following a triple-0 call reporting a stabbing.

On arrival officers arrested a 25-year-old man outside the home before conducting a search inside.

Police discovered the body of a woman believed to be in her 40s who had suffered multiple injuries including stab wounds to her body and face.

Paramedics attempted to revive the woman however she could not be saved.

The man was taken to a police station where he was charged with murder (DV).

NSW Police Superintendent Tracy Chapman said it was believed the pair were mother and son, and it was the son that allegedly made the triple-0 call.

She said there was no known history of domestic violence between the two.

“I’m not aware of any incidents relating to domestic violence matters between the two people,” Chapman said.

“Certainly there are no reports available that indicate there has been domestic violence reports made in the past.”

The man has had very limited interactions with police in the past, Chapman said, and nothing of significance.

Police seized a “household” knife from the home which will undergo forensic examination.

Chapman said police and the government were working “tirelessly” in a bid to tackle domestic violence issues within the community.

“Without question it is a scourge on society and it is a problem within our society,” she said.

The man was refused bail to appear before court on Sunday.

Investigations continues.
