Mr. Smith (81) died from natural causes.
An elderly man who was found dead at his Tipperary home died from natural causes.
However, his wife's cause of death remains unclear.
Earlier this week, Nicholas and Hillary Smith were found dead in their Tipperary home.
According to
The Independent, their bodies were found in separate rooms in their bungalow.
Post-mortem results found that the man, aged 81, died naturally.
Gardaí have now ruled out a possible murder-suicide theory.
Mrs. Smith's post-mortem results were inconclusive.
Post-mortems took place at University Hospital Waterford on Tuesday, June 21st.
Gardaí believe the couple went undiscovered for 18 months.
Locals believed they had moved away from Cloneen during the Covid-19 pandemic.
The private couple kept to themselves, but locals grew concerned for them and alerted Gardaí.
Gardaí have been searching for the couple's next of kin, but have not found any relatives yet.
They're currently looking for relatives in Australia.
Gardaí searched the property after a man spotted the couple's car at the back of the property.
However, nobody had seen the couple since 2020.
Following the tragic discovery, Taoiseach Micheál Martin said it is a "terrible situation".
He also urged the public to keep an eye on one another, especially their older neighbours.
"Obviously I think communities across the country generally do keep an eye out for their neighbours and there are many different organisations and networks that do that.
“And of course, we have to continue to do that and be vigilant in terms of looking after neighbours, particularly the elderly and vulnerable neighbours who may need help and support."
