It is believed nine-year-old Lauren O'Neill was killed by her mother Madeline, who then killed herself at their home in Carryduff in July 2005.

The Eastern and Western Health Boards received the findings of the report into the tragedy last May and say they are taking action on its findings.

Mrs O'Neill was separated from her husband John at the time of the tragedy.

He said he is "devastated by what happened and will be haunted forever by the thought that Lauren would still be alive today had those involved simply followed basic procedures and done their job properly".

The death of the little girl and her mother shocked the entire community.

The report into the deaths of the woman and her child will be made public later today.

Mr O'Neill has called for a public investigation by the coroner into the deaths of his wife and child and called for "robust action" on the findings of the report.

He's also called on Health Minister Michael McGimpsey to act "urgently" so that "no other families will ever again have to endure such pain".

He said he believed "those who bear responsibility for these untimely deaths should be held fully accountable for their shameful neglect of care".

The inquiry has been examining mental health care received by Mrs O'Neill as well as child protection issues raised by the case.

Mrs O'Neill was originally from Derry, and received her last medical care in the city's Gransha Hospital.

She was also in the care of Knockbracken Health Care Park in south Belfast close to where she lived, when she and Lauren died.
