Friends and neighbours of murdered mother-of-three Nicola Collins were deeply worried about her welfare over recent weeks.
One Cork neighbour described Ms Collins (39) as "a bit vulnerable" - and said people living near her on Clashduv Road, Togher, Cork, were very concerned if they didn't see her for several days at her flat.
"You would be worried for her. People knew she had her own problems. I suppose you could say that she might have been a bit vulnerable," he said.
"Neighbours would tend to keep an eye out for her to make sure everything was OK," he added.
Clashduv neighbours were also aware that Ms Collins was spending a lot of time recently in local area Farranree as part of her social life.
The revelation came as a 42-year-old man arrested for questioning over Ms Collins's death was released without charge.
The man, who was known to the Kerry-born woman, was arrested at Popham's Road, Farranree, where Ms Collins's badly beaten body was found.
He was arrested under Section 4 of the Criminal Justice Act, which allowed him to be detained for 24 hours.
The man, who is originally from Charleville but resident in Cork city over recent years, was released without charge from Mayfield garda station yesterday.
Supt Michael Comyn said a file will be prepared for the Director of Public Prosecutions.
