A daughter of a woman who was murdered at her home in Dundalk, Co Louth almost 15 years ago has urged people with information about the main suspect for the crime to contact gardaí.

Jennifer McBride made the appeal after a second man was jailed for life earlier this week for the murder of 43-year-old Irene White in April 2005.

Niall Power, 47, with an address at Gyles Quay, Riverstown, Dundalk, admitted the charge.

Last year, 35-year-old Anthony Lambe, from Annadruman, Castleblayney, Co Monaghan, was given a life sentence after also pleading guilty to the murder.

Power was described in court by his barrister as "the middle man" in arranging the mother-of-three's killing.

He told gardaí he was repeatedly pressurised by another man, who was not before the court, to "sort her out".

In an interview on RTÉ's Prime Time, Ms McBride said: "There was a sense of relief (this week) for the reason that we were told to expect three to four weeks of a trial and there was a lot of anxiety … and what we were going to have to face and listen to and everything like that.

"So it was, like, at least we know it is going to be a positive outcome in the right direction. It is going to be the way we want it to go.

"So there was a sense of relief, but at the same time, pain, anger, hurt. All different emotions. But I was happy to know it was a guilty plea."

Ms McBride said she was making the appeal for information on behalf of herself, her younger brother Damhan and younger sister Dairine.

She said: "People are calling it the 'mastermind' and he's the man behind the whole lot. And the ultimate goal would be to have him before the courts and charged. That would be the ultimate goal, yeah.

"Only then will I feel like I have got true justice for my mam. That she deserves."

Irene White

Ms McBride, who was 17 at the time of the murder, said her mother was "everything" to her, her brother and sister.

"It is just heartbreaking to think in this day and age that people can go around and think that they can pay people to kill a human being. It is horrible," she said.
