The man who killed 59 year-old Pauline Kilkenny has said she "was like a mother to him", a court has heard.
Pauline Kilkenny was stabbed 28 times in the face, neck and chest in her home in Belcoo in 2018. She was also beaten with kitchen pans.
Her body was found by her sister after she failed to turn up for work.
Pauline Kilkenny opened her home to Joseph Dolan in kindness.
A week after the killing Dolan, who is originally from Co Cavan in the Republic of Ireland, told a mental health team at Maghaberry that Pauline Kilkenny was like a mother to him.
He described having flash backs and seeing her face when he woke up in the morning and went to bed at night.
The court was told the 29 year-old has a personality disorder and had taken prescription drugs before the attack.
He also has a history of violence and is a high risk to the public.
Dolan had 27 previous convictions in the Republic of Ireland, including violent disorder.
His defense described the County Fermanagh woman as very good person who was kind and generous, who offered his client a roof over his head when he had very few options.
The defense went on to describe her killing as a dreadful tragedy, and testified that Dolan was shocked and distressed when he realised what he had done.
An impact statement from one of Pauline Kilkenny's nieces was read out in court. She described her aunt as "the epitome of light".
Dolan will be sentenced in two weeks' time.
