The Garda Commissioner says recovering Kyran Durnin's body is an 'obvious point' for the ongoing investigation into his murder.
The schoolboy is missing presumed dead, with a search underway at a property in county Louth.
A man in his 30s arrested yesterday remains in Garda custody.
Garda Commissioner Drew Harris says they're exhausting all efforts to find out what happened
"But I do not think that he is eight years old. I think Kyrin died at the age of six years old and that's where our investigative effort is focused upon that period in May of 2022, and what happened to Kyrin after that last confirmed sighting and how we can develop that on from there"
