A murder trial jury has been shown a video of a crime scene where four members of one family were found dead.
The house where Mandy Power, her daughters and mother died
The Newport Crown Court jury viewed images of the bodies of Mandy Power, 34, daughters Katie, 10, Emily, eight, and her mother, Doris Dawson, 80.
They were found in their burnt-out home in Clydach, near Swansea, in June 1999.
David Morris, 44, from Craig-cefn-parc, Swansea Valley, whose earlier convictions were quashed on appeal, denies murder.
At the opening of the retrial, the prosecution said there had been a "massacre" when the family had been bludgeoned to death with a long pole.
The court was told on Friday that four firemen battled through smoke in a bid to rescue the occupants, but found that they had already been murdered.
The bodies of Ms Power and her children were laid out on the landing of the house, and Mrs Dawson was later discovered in her bed.

As the firemen carried Ms Power and the children from the house their facial and head injuries became apparent, the court was told.
The court was told neighbours had alerted the emergency services after fires set by the killer started to spread through the house.
The video showed the bodies of Mrs Power, her children and Mrs Dawson.
The devastation caused by the fires and the damage which resulted in firefighters' efforts to extinguish the blaze was also filmed.
The jury looked on as reminders of ordinary family life, such as the washing hanging on the line in the back garden and wedding photographs in the bedrooms, were shown on screen.
Blood spatters and other evidence of the extreme violence of the attacks were also evident.
Patrick Harrington QC, prosecuting, has claimed that Mr Morris, of Craig-cefn-parc, had committed the "horrific murders" probably after she spurned his sexual advances.

Mr Harrington said Mr Morris had been living with a woman called Mandy Jewell who had been a close friend of Ms Power, but that the defendant had never approved of the relationship.
He told the court the women had had "a big fall-out" a few weeks before the murders, and Mr Morris "nursed a particularly strong antipathy towards Mandy Power".
He has claimed that Mr Morris went to Ms Power's house where something happened that triggered "an explosion of violence".
This was likely to have been a spurned sexual advance, he said.
The case continues.
