Post mortem examinations have been carried out on the three men found dead at the scene of a housefire in Roscommon town yesterday morning.
The bodies of the men, aged in their twenties and thirties, were found at a vacant house at St Kieran's Park after gardaí responded to reports of smoke.
Gardaí are now awaiting the results of toxicology reports as part of their investigation.
One of the men is understood to be originally from England, while the other two were Dubliners who moved to the area a number of years ago.
