Local people have expressed shock following the discovery of the bodies of two people in a house in Cloneen near Mullinahone.
Some members of the local community had understood that the couple had left the area as they had shared plans to sell the house and relocate.
Garda visited the home to carry out a welfare check based on concerns raised by a community member regarding the lack of maintenance of the lawns.
It is understood that one body was found in a bedroom and the other in the living room.
Chief State Pathologist Dr Linda Mulligan is due to carry out post-mortems today which will determine the course of Garda investigations.
To date no evidence of forced entry at the house was found.
It is understood that the couple were in receipt of pensions paid directly into a bank account and utility bills continued to be paid from the account by standing order.
Gardaí have begun door to door inquiries in the general area to try and establish when anyone may have last seen the couple alive, but it is understood that they were very private and did not mix locally.
Gardai are also trying to establish the location of any relatives of the couple in the UK – the couple are not thought to have any relations in the local area.
Anyone who can assist the investigation is asked to contact Clonmel Garda station on (052) 6177640 or any Garda station
