The mother of twin boys who were stabbed to death by their older brother, who then took his own life, says she thinks parents should be better informed of their children's medication, regardless of age.

It emerged that 21 year old Jonathan O'Driscoll had been off medication for a number of days before he stabbed nine year old Thomas and Patrick more than 40 times each at their home in Charleville, Co Cork, last September.

Doctors would not have to inform family members of any medication once children reach 18.

Their mother Helen O'Driscoll says she would have kept an eye on Jonathan's medication if she'd known about it.

She told presenter Jonathan Healy on Newstalk Lunchtime today that it was very difficult to go back to the house: "You know exactly where they were now, which way they were lying because I didn't know all that before you see, I would never again go inside the door from now on.

"I've been in there twice since. It's been alright but I've come back out again after a few minutes. My husband goes in and lights the lights every night for the children.

"It'll never be a home."

However, she insisted that what happened hadn't changed the way she felt about her son: "Jonathan was my first son, he'll always be my first son. I loved him so much.

"The way he died, I wouldn't wish it on no mother. At the end of the day, I had him when I didn't have the twins. He was my happiness for years.

"It wasn't Jonathan that done it (sic)."

Helen went on to state that she didn't know how sick Jonathan was, saying that she didn't know how much medication he was on: "No I did not know.

"I would have liked to have known. I think that age barrier of confidentiality from an adult... I think that should stop.

"I think their parents have the right to know if they're suffering with some sort of a problem or if they have whatever kind of sickness that they have... They'll look more clearly.

"They reckon he didn't take any medication for about a week when he died."

She insisted that if she wanted any message to come from this, it was for people who have any mental illness to get help: "Anyone at all, I don't care... Phone an organisation, tell their parents, get help.

"Don't stop there or then after a week or two, keep going because those little things build up. I would never like to see another family go through what I'm going through."
