Police have yet to find the gun used to kill Greymouth mum Hayley Williams at her home on Sunday afternoon.
A 45-year-old man appeared in the Greymouth District Court yesterday charged with her murder.
He was granted interim name suppression and remanded in custody until November 10 when he will appear in the High Court in Greymouth via audio visual link from the Christchurch High Court.
West Coast police area commander Inspector Mel Aitken said today few details of the state of the inquiry could be released yet.
Williams' Marsden Rd home remains cordoned off while police continue a forensic examination.
