Hundreds of people gathered tonight at St Mary's Church in Monageer in Co Wexford for a memorial service for Adrian, Ciara, Leanne and Shania Dunne who died at the weekend.
Gardaí have said they will not release details of the post mortems on the four members of the Dunne family until toxicology tests are completed.
The post mortems examinations, carried out by the Assistant State Pathologist Dr Michael Curtis, were completed this morning and the bodies are now being released to the families for burial.
The funeral arrangements are not yet known.
Gardaí say the state pathologists office is not releasing any information pertaining to the post mortem examinations as the results of toxicology tests are not yet back.
It is understood it could be a number of days, possibly weeks, before the outcome of those tests are known.
Meanwhile, Fianna Fáil TD Jim McDaid has said that Ciara O'Briens family had been up and down to Wexford because of concerns for their daughter's welfare and safety.
He said they had been to the gardaí and others in authority on a number of occasions regarding their concerns.
Speaking on Highland Radio this morning, Mr McDaid described headlines in today's papers regarding the deaths of the Dunne family as 'gutter press at its lowest'.
He said the O'Brien family are absolutely gutted at suggestions that their daughter killed her children.
He said Ciara was a very impressionable young woman and he was a very dominant person and they had gone to Wexford a number of times and been fobbed off and told to go home.
Mr McDaid said the newspaper speculation had gutted the family who are trying to bring the bodies of Ciara and her two daughters back to Donegal.
He said speculation in the papers is not taking into consideration her family who refuse to talk until facts are known and who are trying to come to amicable arrangement with Dunne family regarding funeral arrangements.
