Mandy Power's gay lover and the woman initially arrested on suspicion of her murder, has spoken of her relief that David Morris is again found guilty.
Alison Lewis, 39, has now been cleared of any involvement in the murders of her ex-lover, Ms Power's two daughters and their grandmother in June 1999.
But the former police officer said there was still suspicion about her and people had lied about her.
"It is innuendo, suggestion and lies," she told the BBC.
She said she was relieved because Morris would spend the rest of his life being punished and that justice had been done.
Ms Lewis, who has two children, was arrested on suspicion of the murders around 12 months after the bodies of Mandy Power, her children Katie and Emily and their grandmother Doris Dawson were found in their home in Kelvin Road, Clydach, south Wales.
"He will spend the rest of his life being punished for what he did," she said. "There has been justice for Mandy, Katie, Emily and Doris."
Ms Lewis was bailed along with her then husband Stephen Lewis and her brother-in-law Stuart Lewis - both men were serving police officers.
And despite not being charged, Ms Lewis said there was still suspicion about which affected every aspect of her life.
Throughout the retrial David Morris' defence team said Ms Lewis could have been responsible for the murders - an accusation she strongly denies.
"How can anybody think that I would be capable of doing that to Mandy, Doris and the children?" she said.
"I would have given my life to protect them."
However, Ms Lewis admits she can understand why some people might have thought she was guilty and says part of the reason was because the case was "handled badly".
"I think it is because I was arrested," she said. "I went from being Mandy Power's gay lover, to being a suspect, to being arrested and being interviewed to being put on bail for six months.
"I can understand people, because of the way it has been handled, perhaps having doubt over certain aspects of the case. But then I think that is just because the case has been handled badly.
"There is no evidence to say I had any involvement in this murder.
"Anyone who knows me knows that I am innocent and knows that I would never ever hurt anybody, especially not two defenceless children, a lady who was laying in bed and Mandy."
In a press conference following the verdicts, police detective Chris Coutts said the arrest of Alison, Stephen and Stuart Lewis had been a "false trail".
"In any investigation you get false trails," he said.
In the retrial, Morris' defence team portrayed Ms Lewis as an 'obsessively jealous' woman which she also denies.
"I am jealous but I would not say I am obsessively jealous," she said.
"If Mandy Power had been seeing someone else we would have finished. It is a whole different thing to go over and slay three generations over something that would have just ended."
Ms Lewis, who was admitted by her then husband to a psychiatric hospital after a suicide attempt hours after the bodies were discovered, also denied Morris' defence team's claim that she was in a fragile mental state.
Her attempt to leap out of her bedroom window had been an "acute grief reaction", she said.
She also denied claims her ex-husband Stephen Lewis had a motive for murder when he found out about her affair with Mandy Power.
"Stephen never said anything to me that he knew anything about the relationship or that he knew that I was gay," she said.
"The night before Mandy was killed she came to our house and she sat and shared a bottle of wine with Stephen.
"There is no way on heaven and earth that he would have sat there and shared this wine with her if he had known there was a relationship going on between us.
"The first he heard of the affair was when I told him on the Sunday morning after I had heard about the murders."
While relieved that Morris had been found guilty for the second time, Ms Lewis said she would never come to terms with the way the family died.
She also spoke of the value of the retrial because more had come out about David Morris' character.
"David Morris is a violent thug," she said.
"I hate him with every bone in my body. I despise him for what he did that night and for what he has put everyone through."
