Man quizzed over 'Duck Egg' murder was suspect in 2007 gangland slaying
A 25-year-old who is being questioned in relation to the feud murder of Noel 'Duck Egg' Kirwan, was previously held over a separate gangland murder when he was a juvenile.
On Wednesday night, gardai were granted 72 more hours to question the small-time criminal, who was arrested on Tuesday morning.
Officers have been grilling the suspect over the murder of Kirwan (62), who was shot dead on the evening of December 22, last year.
He was the 11th murder victim in the Kinahan/Hutch feud.
"This guy was centrally involved in the murder of Kirwan, make no mistake about that," a source said.
The Herald can reveal that Kirwan's murder was not the first gangland killing that the Rush-based man was suspected of.
He was previously one of a number of men arrested and questioned about the getaway car used in the murder of 36-year-old Sean McMahon, at his home on Donaghmore Avenue, Tallaght.
Mr McMahon was found dead by his partner on November 14, 2007. He had been shot in his bed.
The Kirwan suspect was aged only 17 at the time he was arrested in connection with that case.
Kirwan was shot as he sat in a car outside his home on St Ronans Drive, Clondalkin.
His partner, who was also in the car, escaped unharmed.
Several shots were fired at the victim, including to his head, before the assailant ran to a waiting van, which had another man in the driver's seat.
A white Peugeot Partner van was found burnt out a short distance away at the Neilstown Shopping Centre.
Gardai have been investigating whether he was shot dead after attempting to mediate in a dispute between the Kinahan cartel and their own gangland banker.
Kirwan attempted to prevent the cartel from carrying out an attack on the banker - who also works for the Hutch mob.
Kirwan was a childhood friend of Gerry 'The Monk' Hutch and was a prominent anti-drugs campaigner in Dublin's north inner city during the 1990s.
'Duck Egg' was also a close friend of James 'Jaws' Byrne (69) - the father of slain Kinahan gangster David Byrne (33).
A source said Kirwan and 'Jaws' would have attended several weddings together and were close friends for several years.
Kirwan had close links to the IRA and was previously charged with firearms offences, but later cleared by the courts.
He was cleared of having a firearm or imitation firearm with intent to intimidate a person at Ballybough Road on September 17, 1996.
He moved out of the Summerhill area of the north inner city to Kilbarrack a number of years ago.
It is understood he had been living with his partner in Ronanstown in the years leading up to his murder.
Speaking on RTE's Crimecall in January, his adult son Kristopher and daughter Donna insisted that their father had done nothing to warrant the attack.
"Why did they take his life?" asked Donna.
"I can't understand it at all. What did they think he was involved in at all?"
