As gardaí continue to search the site in Donabate for a missing child, many have questioned the role of Tusla in the boy's life.
Last night, RTÉ reported that the child was fostered for 18 months, and the child returned to the biological family.
This morning, Taoiseach Micheál Martin said it was important that the circumstances of the case were investigated and examined.
"It is a complex situation and there sometimes tends to be a premature reaction to 'blame Tusla for everything,'" he said.
Answers to what happened will not be firmed up until gardaí and the National Review Panel investigate the matter in full.
In the meantime, there is understandable public disquiet and confusion over the decision to return a child to his biological family after being in foster care, however, this is not unusual.
Some foster carers take children into their love and care with an intention to adopt.
Others are happy to offer foster places with the knowledge that family reunion is highly likely.
Family reunion is a key goal of the Child and Family Agency, apart from where there are cases of child sexual abuse or physical abuse in the home for example.
Indeed, relative foster carers (grandparents, aunts, uncles and cousins) have become an increasingly common method of keeping children in their family units.
Tusla would be of the view, according to one source, that while foster parents may give ten out of ten love and care, eight out of ten from biological parents or wider family members is better.
'Difficult news' for foster carer community
That fact that gardaí have stated that the missing child in north county Dublin is likely to be dead, will be difficult news for the foster carer community.
Minister Foley today said Tusla had agreed to conduct well-being checks on cases closed during the Covid-19 pandemic amid the search.
Ms Foley described the case as "hugely disturbing".
Tánaiste Simon Harris said the case of the missing child in Donabate had "shocked the nation" and that it was "deeply disturbing".
In the context of the unanswered questions surrounding the disappearance of Kyran Durnin it is understandable why the public may feel perturbed.
