There were a total of four fatal shootings this year including two people shot dead in a murder-suicide by a man who then took his own life.
Morris ‘Mossie’ O’Sullivan shot his wife Eileen, 56, and son Jamie, 24, at their home in Lixnaw, Co Kerry in September before taking his own life in September.
Patrick Caslin, 26, died in hospital in November days after being found on the ground in Finglas with a gunshot wound to the head but Gardaí suspect he may have shot himself accidentally.
Patrick ‘Pappy’ Lyons, 44, who was shot dead by a local gang in Ballymun in February and Conor O’Brien who was shot dead in Meath in August.
Lyons was shot dead was shot dead in Belclare Terrace in Poppintree in a targeted killing on February 11.
The 44-year-old father-of-two was a drug user with minor convictions but was not considered a major criminal.
Gardai initially were baffled as to why he was targeted but the Garda Síochána Ombudsman Commission subsequently launched probe into whether some gardaí were aware of threats to Lyons' life before the shooting but didn’t disclose this to other gardai until days after the killing.
The probe which remains ongoing was examining claims that officers received information about a threat to Lyons' life 24 hours before his murder but did not tell Lyons and did not tell the investigation team for four days about the threat.
All three gardai had been part of the investigation into Lyons' murder and attended case conferences over the murder but were taken off the case when the claims emerged; however, they were not suspended from duty.
A local gang from the Ballymun area are suspected of carrying out the killing but no one has been charged in connection with the case.
While fatal shootings were low this year, there were also several non-fatal shootings where the targets survived.
Two weeks after Lyons was shot dead, a 17-year-old boy was lucky to escape with his life after being shot twice on Eugene Street in Dublin 8.

When Goulding appeared in court charged in relation to the shooting, Detective Sergeant Michael Redmond said gardai were alerted at 7.04pm on May 25 about gunshots in the vicinity of Whitechapel Grove.
He said the two detectives, who the court ordered cannot currently be named, arrived at the scene and “almost immediately came under fire” from a man in an upstairs bedroom of Mr Goulding’s home.

The detectives were shot in their left legs and one of them was struck in his left hand.

Drug dealer Gary ‘the Canary’ Carey cheated death when a gunman shot him in Ballyfermot, south Dublin, on November 17.
Carey, 40, from Islandbridge Court in Dublin, was sitting in a car outside a house on Ballyfermot Crescent when a gunman fired up to 10 shots at him hitting him twice.
Carey survived a previous attempt on his life last March when a gunman opened fire on him in Ballyfermot but he did not report the attack to gardai. A young criminal from Ballyfermot was the suspect in the March attack and gardai are probing whether the two shootings are linked.
Carey is considered a significant player in the drugs trade in Dublin and has been the target of numerous garda operations.

He was struck in the neck and chest after being attacked in his rented garage.

The hitmen involved in the attack set accidentally set themselves on fire twice while burning out getaway cars.
