Ardee Man Jailed After Supplying Guns to Crime Gangs
A man from Ardee has been sentenced to ten years in prison after admitting his role in importing military-grade firearms from the United States and supplying them to organised criminal gangs across Ireland.
Conor O’Brien (29), of Kilpatrick, Ardee, pleaded guilty to six charges including participating in a criminal organisation and possessing firearms and ammunition in suspicious circumstances.
The offences occurred between February 10, 2023 and July 19, 2024, during which time O’Brien played a key role in sourcing weapons in the United States and arranging their transport to Ireland.
The case was heard before the Special Criminal Court, where judges were told the weapons were ultimately intended for use by serious organised crime groups.
Weapons purchased in the United States
The court heard that O’Brien, who has dual Irish and US citizenship and holds a degree in electrical engineering, used his American status to legally purchase firearms in the state of Nevada.
Once purchased, the guns were dismantled and smuggled into Ireland in separate components by individuals travelling from the United States. The parts were later reassembled and prepared for sale.
Gardaí discovered the weapons during a raid on a shed in Blackstick, Ardee, which O’Brien had rented under the pretext of operating an LED lighting business.
Inside the lock-up, officers found a large cache of firearms, components and ammunition including AR-15 rifle parts, Glock pistols and high-capacity drum magazines capable of holding 60 rounds.
Garda investigation uncovered extensive operation
Detective Inspector Shane McCartan told the court that O’Brien was a critical figure in the gun-running network.
“Without Conor O’Brien, there would be no criminal organisation, such was his importance,” he said.
Evidence presented in court showed that O’Brien worked alongside Mark McCourt, who had previously been sentenced to 12 years in prison for his role in directing the operation.
The organisation was distributing firearms and ammunition to criminal groups operating in Derry, Armagh, Dublin and Limerick, investigators said.
Text messages revealed criminal activity
Forensic analysis of two mobile phones belonging to O’Brien uncovered extensive communications with associates and potential buyers.
In one message to a contact known as “Eugene”, he referred to a “suitcase full of Glocks” and commented that “.22 is for babies”, referring to smaller calibre ammunition.
Other messages showed him discussing collecting “500 rounds of 9mm” ammunition and explaining that he planned “to stick them all together”, meaning the reassembly of firearm parts.
In another exchange with a man known as “Joe”, O’Brien joked that he was selling weapons to “Ireland’s top criminals LOL.”
Investigators also uncovered messages referencing pipe bombs, with O’Brien allegedly sourcing customers while explosives were to be manufactured by McCourt.
Arrest and seizure of weapons In Ardee
Gardaí carried out a raid on the rented shed in Blackstick, Ardee on July 19, 2024, discovering a suitcase containing fully assembled firearms, ammunition and weapon components.
When questioned by officers, O’Brien initially attempted to minimise his role but later acknowledged his knowledge of firearms, telling investigators: “I know guns.”
He also claimed he had been under pressure and feared being assaulted if he refused to travel to the United States to obtain the weapons.
Judge describes offences as extremely serious
During sentencing, Karen O’Connor described O’Brien’s crimes as extremely serious and said they enabled violent criminal activity.
She said firearms are used by criminal gangs to intimidate, maim and kill, adding that the quantity of weapons and ammunition seized in the case was “breathtaking.”
Judge O’Connor also criticised the defendant’s casual tone in messages about selling weapons to criminals, saying it demonstrated a “cavalier and relaxed attitude” towards the harm such weapons could cause.
The court initially set a headline sentence of 15 years, the maximum available for the offences. Taking into account O’Brien’s guilty plea and lack of previous convictions, the sentence was reduced to 11 years with the final year suspended, resulting in 10 years in custody.
The court also ordered that all firearms and ammunition seized during the investigation be forfeited and destroyed, while further submissions are expected regarding cash seized during the Garda investigation.
