Just after midnight on September 4, 1999, Raonaid Murray was murdered savagely with a knife only 500 yards from her home in the south Dublin suburb of Glenageary.
Thursday marked the ninth anniversary of the killing, and this week a Dublin county coroner adjourned an inquest into her death until July of next year while a Garda investigation continues. The murder may remain unsolved, but the case continues to have a firm grip on the public imagination.
Her parents may not wish it, but the 17-year-old has virtually achieved iconic status. Her image still gazes out from the front pages of newspapers.
So why is Raonaid remembered, while many other victims have been forgotten? Perhaps it is because most Irish parents and their teenage children could identify so readily with the killing. Like most suburbs and neighbourhoods in Ireland, Glenageary -- the area next to Dun Laoghaire and Dalkey -- was considered a safe place to walk at any time of the night or day.
The apparently random killing of an innocent teenager on the way back from a pub was all the more shocking because it was so rare -- not just in affluent suburbs of south Dublin, but in the country at large.
Michael Berry, visiting professor of forensic psychology at Dublin Business school, says murders such as that of Raonaid stand out in Ireland because they are uncommon.
"Ireland actually has one of lowest homicide rates of any country in the Western world,'' says Berry.
The numbers may be small, but Raonaid is now part of a distressing litany of high-profile unsolved cases stretching back over two decades. They include: Philip Cairns, the Rathfarnham schoolboy who disappeared without trace in 1986; Annie McCarrick, an American 26-year-old who was last seen boarding a bus to Enniskerry, Co Wicklow in 1993; Jo Jo Dullard, who disappeared while hitch-hiking back to her home in Callan, Co Kilkenny in 1995; and Fiona Sinnott, the 19-year-old mother who went missing in Wexford in February, 1998.
Forensic psychologist Berry says these unsolved cases are particularly difficult to investigate, because most of the crimes were probably committed by strangers.
Typically, according to Berry, the murderer who evades capture is a man over 30. If the killing is planned, he has developed the skills to avoid detection.
The psychologist believes the profile of Raonaid's killer is likely to be somewhat different to this, however.
"I believe it is most likely that Raonaid's killer was aged between 17 and 25. He may have known or thought he knew Raonaid. He may have seen her somewhere and felt that he knew her.''
Raonaid was on her way home after leaving Scotts pub in Dun Laoghaire, when she was attacked and stabbed in the side, chest and shoulder.
While a prime suspect has never been officially identified in the case, Berry's profile of a killer fits in more or less with forensic profiling by detectives.
In the aftermath of her death, the picture painted of Raonaid, who had attended St Joseph of Cluny secondary school, was of a normal teenager who loved George Michael, kept her favourite teddy bear on her bed and dreamt of seeing the world.
To Colin Hill, an assistant manager of Scotts pub, where she visited before her death, she was a friendly, good-looking girl who stood out from the crowd.
Some critics of media coverage of the murder believe that Raonaid's case has been given undue attention, while other killings, particularly those of men in working-class areas of Dublin, stay well below the radar.
