Tribute from Ms Lawless' family
Ms Lawless has been described locally as a "well-liked and independent lady".
She had lived on the Bryndulais estate for many years, and her tragic death is a massive shock to the quiet community in which everybody knows each other.
The family are asking the people of Carmarthenshire, and the community of Llanllwni in particular, to please assist the police in whatever way they can.
Irene leaves behind family members who now have to come to terms with living without her.
Her son Jason said: “She was a loving mother and grandmother, a really peaceful person who loved the garden, animals and her paintings.”
Brother, Phil added: “She was a decent sort, a good sister to have, I wish now to have time alone to grieve.”
If members of the public have information, which could assist the investigation, we would urge them to come forward by calling 101
