Gardaí were yesterday searching through the missing persons database to try to identify a body that was found in south Dublin.
The remains were found by a member of the public at around 7am yesterday and gardaí were immediately notified.
It meant disruption for commuters as some early-morning Dart services were temporarily suspended.
The scene at Blackrock Park in Booterstown was sealed-off as a probe was launched to find out what had happened.
The State Pathologist was notified and gardaí believe the body was there for several weeks before being found in undergrowth.Difficult
Preliminary examinations at the scene did not find any clear signs of injury to the body.
Investigators were last night awaiting the results of a post-mortem examination to determine how they would handle the case.
Gardaí believe the remains are those of a male but were awaiting the post-mortem results to learn of the age, sex and identity of the body.
"This unfortunate person's remains appear to have been in this area for some time before being discovered, which has made identification more difficult," a source said.
"As part of their inquiries gardaí will also be using DNA samples to help identify this person."
This involves the DNA database being used to compare samples from missing persons.
Last year alone DNA profiling was used in solving eight missing-person cases in collaboration with the Garda Missing Person Unit.
The scene of yesterday's find at Blackrock Park runs adjacent to the Dart line between the Seapoint and Booterstown stops.
After gardaí arrived on the scene, early-morning rail services in the area were temporarily suspended but these were back running after 9am, although with delays.
A Garda spokesman said officers are "investigating the discovery of a body on land in Blackrock Park, Blackrock, Co Dublin, on the morning of Thursday, September 17.
"The body appears to have been in situ for a period of time before being discovered.Post-mortem
"The scene is currently preserved for technical examination.
"The body has been removed for post-mortem, the results of which will determine the course of this investigation."
