Jennie Poole's evil killer Gavin Murphy continues to mount attacks behind bars

The Sunday World can reveal how after being placed on remand in Cloverhill following his arrest for Jennie's murder, Murphy was repeatedly disciplined for physically abusing other inmates, smashing up prison property and threatening prison officers.

Our probe has confirmed that in May of last year, Murphy - who murdered health care worker Jennie by stabbing her seven times - was formally disciplined for smashing up a television in his prison cell.

A month later, he was again subjected to a P19 disciplinary hearing, but this time for a physical bust-up with other inmates in his cell.

And, in February of this year, Murphy was P19'ed for a third time when he was disciplined for engaging in threatening behaviour towards prison officers in the same prison.

Last week, Murphy (30) of Coultry Drive, Ballymun, Dublin, was given a mandatory life sentence, having pleaded guilty to murdering Jennifer in her apartment in Melville Drive, Finglas, last year by stabbing her seven times.

He has since been moved to Mountjoy.

A source told the Sunday World: "Murphy made a big deal ahead of writing a letter saying how sorry he was for what he had done.

"But if he is sorry, he hasn't changed his ways.

"He remains a physically violent and abusive character and that poor woman's death had done nothing to change that. Leopards don't change their spots and neither has he."

Last week, the Sunday World revealed how calculating liar Murphy hid his past as a violent abuser of women from loving mum-of-two Jennie when he met her - by covering up a previous stint in jail by claiming he had been living abroad.

Instead of confessing he had been imprisoned in Mountjoy for attacking a previous partner and her mother with a knife, Murphy told carer Jennifer that he had been working away in Spain.

In a heart-breaking interview with the Sunday World, Jennifer's brother Jason called on Justice Minister Helen McEntee to meet with his family to discuss the creation of a 'domestic abusers register' that "could have saved my sister's life".

A spokesperson for Ms McEntee has since confirmed she would be happy to meet with the family to discuss the matter with them.

Jason revealed to us how in the 12 months prior to Jennifer's death, evil Murphy's abuse had altered his sister from an outgoing, happy and confident mother building a future in caring for the elderly, into a woman who lived in fear and made up stories in advance to explain her bruises.

"They were only a year together," Jason said. "They met during lockdown.

"She had met him through a neighbour, who was a cousin of his.

"And, as far as we know, Jennifer was told Gavin had been in Spain.

"But by listening to the evidence that came out in the court, it now appears he was actually in prison and had just gotten out.

"And that is an angry part of this for us.

"Because there were people who knew Gavin and knew what he had done to a previous partner and her mother, and no-one warned Jennifer.

"Never once did someone say to her: 'This is the kind of person he is, you have two young children, be careful.'

"And that's why I think it is so important moving forward that there is a register created to record the names of people convicted of domestic violence, like there is for sex offenders.

"We know that Jennifer was injured and hurt by Gavin Murphy in the past.

"But she didn't know what his past was when she met him, or while this was happening to her.

"And I would love to meet with Helen McEntee about that.

"I would love for her to sit down with us and hear what we have to say.

"There is an elephant in the room in this country and it is domestic violence."
