Clydach murders: Killer David Morris dies in prison

David Morris killed three generations of the same family

The man convicted of the Clydach murders has died in prison, it has been confirmed.

David Morris, 59, killed three generations of the same family in the Swansea Valley village in 1999.

He spent 22 years in jail for killing Mandy Power, 34, her daughters Katie, 10, and Emily, aged eight, and her 80-year-old mother Doris Dawson.

"HMP Long Lartin prisoner David Morris died on August 20," a Prison Service spokesman said.

"The Prisons and Probation Ombudsman has been informed."

Morris, who always maintained his innocence, was jailed for a minimum of 32 years.

He was convicted for the murders a second time in 2006 after an earlier conviction was quashed by the Court of Appeal.

• Morris guilty of Clydach murders

• Fresh doubts over Clydach murders conviction

• 'Nothing to undermine' Clydach murders conviction

Mandy Power and her daughters, Emily and Katie, were murdered in their home in 1999

A bid to again take his case to the Court of Appeal was rejected in 2018 by the Criminal Cases Review Commission.

A BBC Wales Investigates programme in 2020 spoke to two potential new witnesses and South Wales Police announced a review of elements of the case in January 2021.

Doris Dawson was found murdered in her bed

In July the Crown Prosecution Service said no information had been provided by the potential new witnesses to undermine the conviction.

The review, which was being overseen by Devon and Cornwall Police, was then expected to move on to look at forensic issues also challenged in the documentary.

What were the Clydach murders?

A number of fires were lit in the home after the murders

Morris's trial in 2006 heard he had a sexual relationship with Ms Power and was fuelled by drink and drugs when he went on a killing spree in June 1999.

Mrs Dawson was killed as she lay in her bed, and the killer lay waiting for the others to return home.

Ms Power and her daughters were battered with a fibreglass pole, which the children used to play with, and Ms Power's body was sexually assaulted.

Although Emily and Katie Power were murdered, an expert previously said their mother was the main target

The killer lit fires around the house in an attempt to hide the crimes.

Firefighters found the bodies of Ms Power and the girls laid out on the landing when they came to tackle the blaze.

The inquiry was the largest and most complex murder investigation ever undertaken by a Welsh police force.
