Fake gun found as dad and son quizzed over body-in-case murder
Gardai have found an imitation firearm and a fake hand grenade during a search of a house as they continue to question a father and son about the gruesome murder of Kenneth O'Brien.
Members of the garda technical bureau searched the house in Finglas in north Dublin all day yesterday, following on from the arrest of the men on Saturday morning.
The duo - who were not previously known to gardai for involvement in serious crime - are being held at Leixlip and Naas garda stations.
Sources said that an imitation firearm and fake grenade were found during the search and gardai have been investigating the men's links to dissident republicanism.
The army bomb disposal unit was called to the property, but the grenade was quickly declared safe.
It is understood that the younger of the arrested men gave gardai a detailed statement, but sources said detectives were now checking out the details he gave to officers.
A number of garda vehicles were parked outside the Finglas house as the searches were going on yesterday.
It has been established that the father and son knew Mr O'Brien and they became "persons of interest" in the case over a week ago. They had been under surveillance before their arrests.
The young man was arrested in Finglas at around 4am on Saturday. His father was picked up a few hours later.
Mr O'Brien (33) - originally from Ballyfermot in Dublin - was fatally shot once in the head and his body dismembered. His torso was placed in a suitcase and dumped in the Grand Canal at Ardclough in Co Kildare.
Additional body parts were later found in the canal near Sallins, Co Kildare.
The 33-year-old lived in Clondalkin, west Dublin, with his partner and young child.
Gardai believe that the 33-year-old was murdered within hours of leaving his Clondalkin home on January 15.
It is understood that the victim had been either laundering cash for a crime gang or providing them with money when a dispute led to his death.
After being shot in the head, Mr O'Brien's killers cut up his body using a chainsaw and scattered it in different locations in the Grand Canal.
Mr O'Brien's funeral heard about the terrible loss that his family had suffered.
"The sudden loss of Kenneth and the circumstances surrounding his death are more than any parents, partner, son, family, friends or anyone should ever have to endure," a letter from his father Gerry stated.
"We are so grateful to be in a position to be able to put our son to rest peacefully."
