Post-mortem examinations are due to take place today on the bodies of a couple found dead at their home in Co Cavan.
Rolandas Jarmalvichius and his partner Rita Martinkiene, originally from Lithuania, were found dead at the house they rented at Drumbrawn in Cloverhill at around 8pm on Sunday night.
They had been living in the area for a number of years and worked in Co Fermanagh. However, the couple had not been seen in a number of days.
Their bodies were removed from the house yesterday and taken to Our Lady's Hospital in Navan for post-mortem examinations.
Gardaí say the results, along with toxicology tests, will determine the course of the investigation.
However, it is believed the couple died as a result of accidental poisoning.
