Gardaí are waiting to speak to two people who were injured in a stabbing incident in Bray early yesterday morning that left two 22-year-old men dead.
Detectives believe Shane Clancy stabbed Sebastian Creane to death at the Creane family home in Cuala Grove, Bray in what a Garda source described as a “frenzied” knife attack. He also stabbed Dylan Creane and Jennifer Hennigan before killing himself.
Gardaí are investigating the theory that Mr Creane was attacked because he was romantically involved with Ms Hannigan, who was Mr Clancy’s ex-girlfriend.
Postmortems are being held today on the bodies of the two dead men.
Gardaí investigating the deaths said the two survivors were "very lucky" to be alive.
Dylan Creane was stabbed eight times and suffered a punctured lung. Ms Hennigan (22) from Bray, managed to crawl to a nearby house to raise the alarm despite being stabbed in the back. When Ms Hennigan was admitted to St Vincent's hospital, staff realised the blade of the knife she had been stabbed with had broken from the handle and was embedded in her back.
They underwent surgery yesterday and are expected to survive.
Senior Garda sources said they were satisfied Mr Clancy, a student in Trinity College Dublin from Dalkey, had stabbed the three victims, killing Sebastian Creane and injuring his brother Dylan and Ms Hennigan.
Mr Clancy was found dead in the back garden of the Cuala Grove house yesterday morning. A knife was found with his body. Gardaí are not looking for anybody else in relation to his death.
Sebastian Crean, a student at Dún Laoghaire Institute of Art, Design and Technology, and his attacker were out socialising with a group of friends late on Saturday night into yesterday morning. They were then driven to the Creane family home, where they were later joined by Ms Hennigan.
At some point just after 4.30am, Mr Clancy fatally attacked Sebastian Creane with a knife. He then attacked Ms Hennigan.
Dylan Creane (28) was in bed at the time and ran downstairs when he heard the attack. He was stabbed eight times by Mr Clancy when he intervened.
Ms Hennigan managed to crawl over a wall into a neighbour’s house and raised the alarm just before 5am.
A second woman who was upstairs in the house when the stabbings took place was uninjured.
The Creanes’ parents were away on holiday and returned to Ireland yesterday. They were met off their British flight by a team of gardaí.
