Convicted criminal Brian Rattigan has been jailed for killing a man outside Abrakebabra in Crumlin.
It’s believed Declan Gavin's death sparked the Crumlin/Drimnagh feud that ended up claiming 16 lives.
The 20-year-old was socialising in 2001 with a group of friends, when a car pulled up.
Brian Rattigan got out of the car high on alcohol and drugs, and began shouting and stabbed Declan twice.
Declan ran into Abrakababra, and Rattigan tried to follow him but the doorman locked the door.
However, one of the stab wounds had penetrated Declan’s heart and he died.
Rattigan was jailed on his second trial for murder but the Supreme Court overturned that and he pleaded guilty to the lesser charge of manslaughter.
As he jailed him for nine years today, the Judge said Rattigan’s apology to the family was "too little too late".
Rattigan has been behind bars since 2003 and in 2013 he was convicted for the sale or supply of drugs within prison.
He has been due for release from that crime this November.
However, this manslaughter sentence means he won't be out until at least 2025.
