Further tests are to be carried out today on the bodies of a Dublin couple found at their home yesterday.
The alarm was raised at about 5 o'clock yesterday afternoon when a relative called to the house in Landscape Park in Churchtown.
The remains of the couple in their 80's were found inside.
Gardai say the deaths are not being treated as suspicious, and it's reported there were no signs of a break-in.
Gas Networks Ireland has said there was no gas leak at the scene.
