Gardaí have confirmed a legally held firearm was held in the family home of three people who died violently.
Listowel gardaí have begun a criminal investigation into the suspected double murder and suicide, near Lixnaw.
56-year-old Eileen O'Sullivan and her 24-year-old son Jamie were shot dead in their home in Kilfeighney last night.
The body of Eileen's partner, 63-year-old Mossie, was found in a nearby field alongside a shotgun shortly afterwards.
All three had gunshot wounds and a firearm was recovered near Mossie O'Sullivan's body.
Superintendent Paul Kennedy of Listowel Garda Station confirmed a legally held firearm was held in the home:
Locum Assistant State Pathologist Dr Margot Bolster and the Garda Technical Bureau have commenced an examination of the scene; this examination is ongoing.
All three bodies have been removed to University Hospital Kerry, where post mortems will take place.
