The man who died in a gun attack at Bray Boxing Club on Tuesday morning has been named as 50-year-old Bobby Messitt from Kilmacanogue.
A 30-year-old man was killed and gardai say his body remains at the scene pending the arrival of the State Pathologist.
Bray Boxing Club was set up by Pete Taylor in February 2014 and his Olympic, European and World champion daughter Katie has previously trained there.
The incident took place at about 6:55 am this morning and the three men are believed to be seriously injured.
Mr Taylor is thought to be in a serious but not life threatening condition.
He then turned and shot Mr Taylor and the other injured man.
She went on to win gold at the London 2012 Olympics and she is unified lightweight world champion.
Irish police said that the suspected attacker left the scene of the shooting silver-coloured Volkswagen van with Northern Ireland registration plates.
There is still a heavy police presence at the club while forensic officers carry out their investigation.
Gardaí are appealing for witnesses or anyone with information to contact Bray Garda Station on 01 666 5300.
Fellow councillor Michael O'Connor added: "Pete Taylor was shot".
Ireland's Health Minister Simon Harris called the news "shocking" but said he had "no doubt that the Gardai are doing all they can to apprehend those responsible".
"Another dark day for Bray".
