A house in the village of Convoy in Co Donegal has been sealed off after an elderly couple were discovered to have died inside.
The couple were found earlier today by neighbours who alerted gardaí.
The coroner for Donegal Dr Denis McCauley is on his way to the scene to carry out a further examination of the bodies.
A full garda forensic examination is expected to also take place.
The married couple were very well-known in the area.
A Garda spokesman said: "We simply cannot say at this stage how they died.
"A full examination of the scene will be carried out to determine what direction our investigation will take."
