'Your daughter is a waste of space w****': Sickening text killer, 31, sent to his girlfriend's mother after he stabbed her to death is revealed as judges kick out his appeal against life sentence
The mother of woman murdered by her abusive ex has revealed the terrible text he sent her before the killing.
Jason Cooper stabbed his ex-girlfriend Laura Stuart to death in Denbigh, Wales last summer after she ended their abusive relationship.
He was jailed for life in March but today brought his case back to court pleading for a shorter minimum term.
Ahead of the hearing, Ms Stuart's mother Elizabeth Griffiths revealed the abusive text he sent her days before the stabbing.
It read: 'Your daughter is a fat disgrace she is and has been f***ing [person's name]. I f***ed her that Wednesday she came my house for help! She is a waste of space w***e.'
Mrs Griffiths was left relieved however when judges kicked out Cooper's claims, insisting he deserved a long sentence because he appeared 'proud of what he had done'.
Cooper attacked mother-of-two Miss Stuart in August last year and stabbed her friend David Roberts who tried to intervene.
Her mother said: 'He's not even a person any more. I can't hate him because he's non-existent.. I will never forgive him.
'He was given 25 years for killing Laura and six years for what he did to Dave. They can only reduce his sentence to 25 years on appeal but it would make a mockery of what Dave went through.
Mrs Griffiths, 55, said Cooper sent her daughter 421 texts in just one day as part of his campaign of abuse before the killing.
She added: 'Police need to recognise these situations. Surely there is something you can put in place on someone that is harassing someone.
'He didn't just do it to Laura. He did it to me and to her daughter. He said the most awful things on the phone to her. She was just 14.'
After the murder, Cooper told a witness: 'I said I was going to do it - and I did'.
He denied murder, but was convicted at Mold Crown Court in March and was jailed for life, with 31 years to serve before seeking parole.
His lawyers today asked appeal judges to the minimum term to allow Cooper to apply for parole sooner.
But three of the country's top judges sitting at the Court of Appeal in London rejected the claims.
Dismissing the appeal, Lady Justice Hallett, sitting with Mr Justice Stuart Smith and Mrs Justice May, said 31 years was appropriate for the terrible murder.
Lady Justice Hallett said: 'He caused huge distress and grief to many people, including two children who must grow up without their mother.
'Far from showing remorse, he appeared to be proud of what he had done.'
An Independent Office of Police Conduct (IOPC) investigation is still ongoing into 18 reports made to the force involving Laura or Cooper prior to her death.
Dismissing Cooper's pleas for a shorter sentence today, Lady Justice Hallett said of the killer: 'He armed himself with a knife and took it to the scene specifically to use it to kill Miss Stuart.
'He planned to kill because, if he could not have her, no one else could.
'He made sure Miss Stuart knew of his intention and succeeded by stabbing her several times and kicking her in the head as she was defenceless and bleeding.
'Furthermore, there was a background of coercive behaviour.
'The mitigation was limited - he had no previous convictions.
'But, far from showing remorse, he appeared to be proud of what he had done.
'We have considered with care the judge's very full sentencing remarks. He sets out precisely why he took such a serious view of Cooper's conduct and culpability.
'Jason Cooper killed one young mother and nearly killed a friend with no justification or provocation whatsoever.'
