Partner charged with murder in Sydney

A man has been charged with the murder of his partner after the couple's son reportedly found the 56-year-old woman's body in the kitchen of their northwest Sydney home.

Police were called to the Glenwood residence on Tuesday afternoon following the gruesome discovery.

A 57-year-old man was arrested several hours later by police at a nearby Kings Langley shopping centre, and authorities also seized his car as part of their investigation.

Neighbours have told the Seven Network the woman had been living in the back shed on the property for some time.

The man has spent the night in police custody and is due to face Blacktown Local Court on Wednesday.
