The BBC's Hefina Rendle reports on the family's anguish

Sandie Bowen was killed at the home she shared with husband Mike in Monmouthshire just hours after he had learned she was having an affair.

The body of 54-year-old Mrs Bowen has never been found, despite an extensive search by police.

Forestry worker Mike Bowen was convicted of her killing last year and is serving a life sentence.

The Bowens lived at Llandogo

Gwent detectives have taken the unusual step of travelling to Folkestone for the thanksgiving service.

They believe Bowen has buried his wife's body in the forests where he used to work.

A note written at the time of her disappearance in August 1997 suggested she was planning to leave her husband, who she had been married to for four years.

Bowen later unsuccessfully appealed against his conviction.

Thanksgiving

Mrs Bowen's daughter, Anita Spencer, says she has waited two years for this day and she wants the service in memory of her mother's life.

Mrs Bowen had lived in Kent before she moved to Wales to marry.

In the family church in Kent, there will be a service of thanksgiving for Sandie Bowen's life.
