A man has been arrested in connection with the death of Miriam Burns in Kerry last August.
She was found dead in her home in Ardshanavooley in Killarney.
A man in his 50s was arrested this morning and is being questioned at a Garda Station in Cork City.
Miriam was described as a very stylish and very warm woman after her death.
Locals said she was very well known around Killarney and very well liked.
"She would always stop for a chat and she'd have something cheerful always to say to liven up your day."
