A MOTHER-of-three was beaten to death with a hatchet in her bedroom.
Susan Dunne (53) was attacked in her home and left with "catastrophic" injuries.
A 19-year-old suspect was later arrested and remains in garda custody today.
Ms Dunne's body was found by neighbours in a bedroom of the cottage she shared with her son in Ballinageragh, Lixnaw, Co Kerry at around 9.30am yesterday.
Gardai are expected to upgrade the investigation to a murder probe following the completion of a post-mortem examination of Ms Dunne's remains today.
