The sudden death of west Belfast mother Eimear Clarke is no longer being treated as suspicious, say police.
The 30-year-old's body was discovered at her house in the Derryveagh Close area of Lenadoon early on the morning of Easter Sunday.
Police officers were called to the house shortly before 6.30am and arrested a 36-year-old man.
He was released unconditionally on Monday night.
A post-mortem examination was completed on Monday but police said they were awaiting the results of more tests.
Ms Clarke had a young family and had lived in the Lenadoon area her whole life, attending nearby St Genevieve's High School.
Neighbours, who were shocked at her death, described her as fun-loving and kind.
"She loved kids and was very generous," one said.
