The prosecution in the Clydach murder trial will begin its closing speech to the jury, as the case draws to an end.

Patrick Harrington QC will then be followed by the defence barrister, Peter Rouch QC.

Mr Morris denies all the charges

David Morris, 40, of Craig Cefn Parc, near Swansea, denies the brutal murders of Mrs Power, 34, her daughters, Katie, ten, and Emily, 8, and her 80-year-old mother, Doris Dawson.

The four were bludgeoned to death at their home in Kelvin Road in Clydach, near Swansea, three years ago in what the prosecution described as a "massacre".

Mr Morris is accused of the murders in June 1999 after his sexual advances were allegedly spurned by Mrs Power.

He then set fire to the house to conceal his crime, the prosecution claimed.

Earlier in the trial, the jury has heard police found a gold necklace lying in a pool of Mrs Power's blood on the bedroom floor, and the prosecution has alleged that it belonged to Morris.

On Tuesday, the final witness for the Clydach murder trial defence has said she saw a serving police officer - who had been a former suspect in the case - in the street at around the time of the killings.

Defendant David Morris claims Alison Lewis "probably" killed the family

The court heard that Nicola Williams later identified him as Stephen Lewis, the former husband of Alison Lewis - who was the lesbian lover of murder victim Ms Power.

Previously, the jury at Swansea Crown Court had heard that Mr Morris believed the bisexual mother-of-two was "probably" murdered by Mrs Lewis.

The defence claims Stephen Lewis then helped his wife by clearing evidence from the murder scene.

Both were arrested one year after the killings on suspicion of murder and were released without charge after four days of intense police questioning.

The case continues.
