The savage attack on three generations of the same family is the most horrific case in recent Welsh history and one that made headlines across the UK.

For three years, the family of the victims - Mandy Power, her elderly mother Doris and her two daughters - have waited for justice.

On the day that 40-year-old David Morris is sentenced to four life terms for their murders, the programme talks exclusively to Mandy Power's brother and sisters, and others close to the family.

The programme is broadcast on BBC1 Wales at 2055 BST on Friday and can be watched live online.
