Naas Gardai last night released the 47 year old man whom they were questioning in relation to the discovery of the body of a woman in Lacken View last Sunday morning, August 19.
He was not charged and a file will be sent to the DPP.
Liz Duff, nee Dempsey, also 47, was found dead at the bottom of the stairs in her home. Her body was wrapped in a blanket. It is thought she may have been there for some hours.
On Tuesday, August 21, a man was arrested and questioned by Gardai in relation to the discovery. The man is known to Gardai.
State Pathologist, Dr. Marie Cassidy conducted a full post-mortem examination on Monday, and in a statement issued on Tuesday evening, Gardai said they would not disclose the findings of the report for operational reasons.
However the Leinster Leader understands that the report concluded that the victim died as a result of injuries sustained while falling down the stairs and Gardai are keeping an open mind on whether her death was suspicious or not.
The 47 year old man, who was known to the victim, was arrested on Tuesday and initially held for 24 hours. Gardai applied on Tuesday night to extend his period of detention for a further 24 hours.
Elizabeth Duff was the mother of four children, a son and three daughters. She is originally from a well known and respected Kilcullen family.
Neither her family nor her neighbours in the tight community of Lacken View would speak to reporters when approached.
