The report on the Monageer tragedy has found that Adrian Dunne frequently misinformed service providers by furnishing misleading information.
Read the Monageer Inquiry report
The 29-year-old took his own life after killing his wife and two children during the weekend of 20-23 April 2007.
He also tended to fabricate stories about family trips abroad and the deaths of an entire family in a car accident, which the inquiry team found to be untrue.
Ciara Dunne, Adrian's wife, was found to have colluded with him on occasions with such stories.
The purpose of the inquiry, which was closed to the public, was to establish the circumstances surrounding the deaths, and the dealings of State services with the family and each other.
It was chaired by barrister Kate Brosnan and its members included retired assistant Garda Commissioner Jim McHugh and Leonie Lunny, Chief Executive of the Citizens Information Board.
Its final report was to be completed and forwarded to Minister for Children and the Minister for Justice a year ago.
However, delays occurred because of the large volume of people who were interviewed as part of the inquiry, and the complexity of their evidence.
The current Minister for Children, Barry Andrews, received the report last October, although extracts of it have been circulated to relevant bodies and family members over recent months for legal reasons.
Adrian Dunne was 'driving force'
Adrian Dunne's wife Ciara, 24, died from strangulation and their two daughters, Leanne, 5, and Shania, 3, were smothered.
The inquiry team found that Adrian Dunne was the driving force behind what they describe as the planning and execution of the deaths of the three.
It also did not discover any single definitive motive behind the deaths.
The time of death could not be established with certainty but the inquiry team believe the two children, and Ciara Dunne, probably died on the Saturday morning, 21 April, shortly before a 'suicide' text message was sent from Adrian's phone at 10.17am.
They believe Adrian Dunne died shortly after that.
The inquiry also found that if gardaí or social services had called to the Dunne family home during the course of the weekend, it is likely the tragedy would not have been averted.
The report says gardaí should have considered contacting Adrian Dunne's family to advise them of his visit to an undertaker on the Friday before the deaths.
In another finding, the inquiry team says that a fundamental problem has been the State's failure to provide 'out of hours' social work service to ensure a response to all serious child protection and welfare concerns.
The solicitor representing the Dunne family said in his opinion and in the opinion of the family the report is a 'whitewash'.
John Murphy said the report was 'useless' in that it did not get to the heart of the gaps in services, which existed at the time.
The report makes a number of recommendations pertaining to both the HSE and gardaí.
A total of 26 recommendations are contained in the report. However, seven of the recommendations have been blacked out.
Minister says 'no question of cover up'
Minister Andrews said that providing a national out-of-hours service, as recommended by the report, was not an option because of the current economic situation.
He said number of aspects of the report had been censored due to legal advice but denied there was any question of a cover-up.
Mr Murphy said the report should have been published in full with the censored sections also published.
Reacting to criticism of the report by the Dunne family, Mr Andrews said the inquiry team had been a sensitive as possible to the family and had liaised with them throughout the process.
He said the report had been given to them as soon as possible.
Minister Andrews said the report's key finding was that the death of the family could not have been prevented.
Garda Commissioner Fachtna Murphy said he accepted the findings of the report and 'is committed to ensuring that the safety and protection of children is a key priority for An Garda Síochána'.
Speaking before publication of the report, Des Kavanagh, general secretary of the Psychiatric Nurses' Association, said there had been a 'number of positives and negatives' since the tragedy.
He told RTÉ's Morning Ireland that the Wexford mental health services have responded by putting in place mental health liaison nurses into the A&E services in Wexford General Hospital.
‘They have also put in place a suicide-screening nurse who is available to work with GPs, and that is covering one half of the county and is intended to be extended to the full county.’
In national terms, he said the provision of a mental health specialist'who is supposed to be available 24 hours a day' was 'hugely important'.
'We believe it ought to be done on a guaranteed service basis, but unfortunately the particular resources available mean it is available only on a voluntary basis,' Mr Kavanagh said, adding this situation was 'a bit chaotic' and 'unacceptable'.
