Gunman had been on bail after he was charged with membership of the IRA
The man suspected of shooting dead a garda before turning the gun on a woman and then taking his own life was last night named as Adrian Crevan Mackin.
The 24-year-old gunman had been on bail awaiting trial for IRA membership at the Special Criminal Court in Dublin after being arrested following a joint Garda-PSNI operation to target dissident republicans.
Mackin, with an address at Mullach Alainn, Omeath, Co Louth, was charged with membership of a group styling itself the IRA. He was charged under Section 21 of the Offences against the State Act 1939 on January 18 last. Mackin - who is originally from Newry - was remanded in custody but later released on bail.
He was due back before the three-judge non-jury court on October 27 when his case was listed for mention.
Gardaí were alarmed at reports their colleague had been sent unarmed to a potentially dangerous domestic violence situation..
There was no official confirmation last night but it is a general rule in the Garda that uniformed officers are unarmed. Sources said that if it had been known in advance that Mackin had been charged with IRA membership it would merit an armed response by gardaí.
It is not known if this was available in the area at the time. Garda expressed similar sentiments at the time Detective Garda Adrian Donohoe was shot in Dundalk in January 2013 when he and his colleagues, armed only with standard-issue handguns, were surprised by a gang armed with a shotgun.
In 2012 Mackin was charged with having photographs of women having sex with animals.
He was accused of possessing 23 "extreme pornographic images" stored on his computer.
