The sister of an evil killer who murdered three generations of the same family in cold blood has spoken out after he died in jail.
David Morris killed Mandy Power, 34, her 80-year-old mum Doris and her two daughters, Katie, 10 and Emily, eight, in 1999.
Morris bludgeoned the family to death with a metal pole and left them to burn in a fire at their home in Clydach, Wales, in a crime that shocked the nation.
Two serving South Wales Police officers were originally suspected of the murders but were never charged, and Morris, a local labourer was arrested, charged and handed four life sentences.
He was convicted of the killings twice – initially at Swansea Crown Court in 2002, a verdict which was overturned on appeal, and then subsequently following a retrial at Newport Crown Court in 2006, WalesOnline reports.
Morris told investigators he was having an affair with Mandy Power behind the back of his girlfriend and Mandy’s best friend, Mandy Jewell, at the time of the killings.
His alibi on the night of the killings from late on June, 26, to the early hours of June, 27, 1999, has always been unclear. He told police he went for a walk to calm down after a row with Mandy Jewell in a village pub before returning to the flat he shared with her n the early hours.
He said she let him in at around 3am, although she originally told police he had arrived home between 10.30 and 11pm only to then tell the jury during his trial that she did not know what time he arrived home.
Morris died in prison earlier this year. His family have always maintained his innocence.
Speaking for the first time since his death, Morris’ sister Debra Thomas insists the family were not simply blinded by loyalty.
Debra – who led a campaign called Free Dai Morris – told WalesOnline: “A lot of people have a past but that does not make them a murderer. David was a good son to our parents. He absolutely adored our mother.
“When he got in trouble my mother would cry and our father would shout. But he never cheated them. He was up their house every day. Whatever needed doing in the house he would do it for them – decorating and the like.
“Growing up in the 60s and 70s we didn’t have computers and televisions everywhere so we looked out for each other and that brought us together.
“He was a brilliant father. He was always there for his daughters and they loved him. I’m convinced the stress of it all contributed to our mother dying young – she was 67 when she passed away. I had to watch her go through all that and it has been torture.
“She went to see him when she was able to and we would take her before she got too ill.”
Debra said had the family ever believed Morris was responsible for the June 1999 quadruple slaughter they would have severed ties with him immediately.
“Lots of people have only read what is in the paper and they then convict him,” she said.
“We haven’t been campaigning for him through blind faith. What happened was absolutely horrendous – you can’t begin to understand the [Power] family’s pain and suffering. But I know David was not guilty. If there was any evidence that showed he was we would have cut him off in an instant.
“You need to cut out the emotion and look at the facts. That is why we have such massive support for our campaign. We had been fighting for so long and then suddenly the campaign really took off. We have never had any trouble from people over it.
“The dream was one day he would be freed – but now that will never happen.”
Debra said her brother had been “fine” prior to his death, but did have some ongoing medical issues. A post-mortem examination into his death proved inconclusive, an inquest opening heard.
The hearing was told that Morris “came out of his cell and collapsed early in the morning and, despite attempts at resuscitation, he was confirmed dead at 8.43am on his wing block.”
Debra said: “We don’t know yet the cause of his death but he had heart problems and was insulin-dependent. Everything points to his heart but we have to wait for toxicology.
“He had been fine recently. He had to have hope and he knew we were fighting for him and we would never give up. And we will go on. We are going to fight 100% to clear his name. There are still questions to be answered.”
Morris’ daughter Janiene was just 21 when her father was arrested. In February this year, she said: “I just think, taking the emotion out of this, there are so many unanswered questions in this case – more than enough for anyone to think that something isn’t quite right here.
“I never believed for one minute that my dad was capable of such violence – it simply wasn’t the man he was. There was just no way that it was ever possible that he would have been able to commit those murders.”
