Detectives have issued a description of a man and woman they want to interview in connection with the murder of Raonaid Murray who was stabbed to death in Dublin in 1999.
Ms Murray was 17 when she was attacked just yards from her home in Glenageary, Co Dublin.
Her body was discovered at Silchester Crescent, Glenageary, in the early hours of September 4th, 1999. The last definite sighting of the teenager was of her leaving Scotts pub in Dún Laoghaire at 11.20pm on September 3rd.
This morning gardaí held a press briefing to announce the details of these previously unknown individuals they are interested in speaking to in relation to the murder.
Det Supt John Mulligan, senior investigating officer, Dún Laoghaire, today said that it was known that at 12.07am on Saturday morning, September 4th, 1999, a young man crossed over Silchester Road just after the walk-way known as "The Cut" and walked down towards Adelaide Road.
Gardaí are also appealing to a female who was in the vicinity of Silchester Park between 12.20am and 12.30am on Saturday morning to come forward.
The man in his 20s is said to be 5'10" tall and was wearing dark clothes. He was seen on Silchester Road around the time the student was stabbed. The woman was seen in the area 15 minutes later and is described as being aged between 16 and 23, 5' 6" in height, with dark shoulder-length hair.
Gardaí did not rule out the possibility that the man and woman may have been together.
More than 8,000 people have been interviewed in the Garda investigation into her death and almost 3,000 statements taken. There were 12 arrests but no-one has been charged.
Gardaí are appealing to anyone with information to now come forward and contact the Incident Room in Dún Laoghaire on 01-6665032, the Garda Confidential Line 1800-666-111 or any Garda Station.
People can also provide information through Crimestoppers on a free phone line 1800-250025 anonymously and confidentially. There may be a reward.
Last week Ms Murray’s parents, Jim and Deirdre, launched a new website to commemorate the 10th anniversary of her death.
The website, www.raonaid.com, also represents an appeal for further details surrounding her death. Anyone with information can contact 087 0635 462.
