A MAN in his 50s has been released from Garda custody after being questioned about the murder of the west Dublin woman, Ms Geraldine Diver.
Gardai questioned the man throughout yesterday at Lucan Garda station.
A file on the week long investigation is being completed and will be sent to the Director of Public Prosecutions, who will decide whether or not the man is to be charged with the murder.
The man was arrested at 10.05 a.m. yesterday at a house in west Dublin. He was held for questioning under Section 4 of the Criminal Justice Act, which allows a person to be detained for questioning for 12 hours, after which he must be released or charged.
Mrs Diver was strangled while sitting in her car outside Buckley's builders' providers on Robinhood Road in west Dublin on Monday evening. She was not sexually assaulted and her purse was not taken.
It is understood Mrs Diver was on her way to see a friend, a Crumlin man in his mid 20s, who identified himself to gardai the next day and was eliminated as a suspect.
It is believed the man who strangled her was in the front passenger seat of the Renault car and was known to her.
Mrs Diver, the mother of a 13 year old girl and nine year old boy, had left work in the Coombe Hospital around 9 p.m. on Monday to return to her home in Kilnamanagh Road, Walkinstown.
Her body was found by a security man at Buckley's shortly before 11 p.m. She had been strangled with a neck tie and the tie then attached to the head rest of the driver side front seat in the car.
Her killer was pictured on video footage taken from a security camera mounted on the front gate of Buckley's.
A team of detectives was involved in yesterday's questioning under the direction of the head of the Central Detective Unit, Chief Supt Sean Camon.
