Brutal murderer who killed three generations of the same family dies in prison

The man accused of the brutal Clydach murders has died in prison, The Mirror can reveal.

David Morris, 57, was behind bars for the killing of mum Mandy Power, 34, her 80-year-old mum Doris and Mandy’s two little girls Katie, 10, and Emily, eight, in 1999.

It was a crime which shocked the nation when it happened in a quiet suburban street in Clydach, south Wales.

At first thought to be a tragic house fire investigators soon realised the full horror of the scene before them.

It was revealed the family had been bludgeoned to death with a metal pole and left to burn in a fire set to seemingly cover up the heinous crime.

One former and two serving South Wales police officers were initially suspected in a sensational love triangle plot but were never charged and local labourer David Morris was later arrested.

Last night it was revealed Mr Morris died suddenly at Long Lartin prison in Worcestershire of a suspected heart attack.

But his family have long since protested his innocence and a campaign was slowly growing to have his convictions overturned.

Earlier this year South Wales police launch an independent review into the case.
