The gunman who shot and killed Daithí Douglas in Dublin's south inner city was captured on CCTV in the seconds before the murder, and the seconds immediately afterwards.

The hooded figure is seen walking along Oliver Bond Street towards the junction with Bridgefoot Street, in the heart of the Liberties.

External and internal CCTV cameras capture the hooded figure as he approaches Shoestown, Mr Douglas’ shop, on Bridgefoot Street.

The imagery speaks for itself. The gunman walks to the murder scene, his gun hidden. While he doesn’t run, he walks quickly.

Behind him, a car reverses in tandem with him. That car is a stolen Mercedes, which is what gardaí would later term the "murder car".

The getaway driver is moving the vehicle closer to the murder scene, ready to speed away once the killing occurs.

The gunman who killed Daithí Douglas in Dublin's south inner city

And it all occurs within a matter of seconds. It is 4.11pm on Friday 1 July 2016. In broad daylight, a man is murdered – shot six times in the upper body.

Daithí Douglas was a man with an interesting past, and, by the time of his murder, a man with a different and equally interesting present.

A former member of the IRA, Mr Douglas was sentenced to 12 years in prison in the early 1980s for a series of armed robberies in Dublin and Limerick.

When he was released from that sentence, he became involved in organised crime, and received a sentence for being in possession of €500,000 worth of cocaine.

But when he was released from that term in prison, he seemed to "go legit".

He had turned a corner in his life: He was married, he had a daughter, and he worked with his wife in their shoe shop close to Thomas Street, the Liberties’ main thoroughfare.

Mr Douglas was originally from Cabra on the north side of the city, but he fitted in well in the Liberties, and was well regarded by other local business people.

He never denied his past, but said that it was the past. To borrow a Dublin phrase, gardaí who investigated Mr Douglas’ murder told me that many local people who knew Daithí Douglas would have described him as essentially a "decent skin".

But Mr Douglas became a target for criminals in the south inner city because of previous links he was said to have had with elements of the Hutch gang in north Dublin.

A totally incorrect rumour linked him with a failed 2015 gun attack on an associate of the Kinahan organised crime group.

The rumour was false. Subsequent garda investigations would show that Mr Douglas was in another part of Dublin when the incident occurred on the Naas Road.

But the rumour was enough to seal Mr Douglas’ fate. He became a target for a criminal cell that included Frederick Thompson, a well-known criminal from the south inner city.

At the very moment Mr Douglas was shot dead, Frederick Thompson was standing on a nearby street.

The CCTV footage, which was shown in court during his trial in 2018, showed Mr Thompson dismantling a mobile phone and handing it to another person. He is also seen manipulating a SIM card in an effort to break it up.

Just moments earlier, Mr Thompson had driven by Mr Douglas’ shop, in what prosecuting counsel Seán Gillane said was a final "recce", or reconnaissance – a last look to see if the intended victim was in his shop.

Mr Gillane said at Mr Thompson’s trial that although there was just one finger on the trigger, "there were many hands on the gun" that shot Mr Douglas.

Frederick Thompson captured on CCTV footage

At the most recent trial, the prosecution had said it believed Lee Canavan was the actual gunman, but the court said that it did not believe there was enough evidence for it to reach this conclusion beyond reasonable doubt.

The court did however find Mr Canavan guilty of murder, and this was based on an analysis of CCTV, forensic evidence and other evidence.

The murder plot that day involved the use of four vehicles – two stolen cars and two legitimately owned cars that were "borrowed" for use that day.

A Mercedes stolen in June 2016 from Dublin’s Navan Road was the "murder car".

It was burnt out close to Francis Street minutes after the murder. A Suzuki Swift, which was stolen in Greystones in Co Wicklow, was the so-called "swap car".

After the murder, after snaking its way along city streets, the swap car was left at a coastal car park near the Martello Tower in Dublin’s Sandymount.

Many of the cars’ movements were caught on camera. Over 1,500 hours of CCTV footage was analysed by gardaí investigating the murder.

Detective Garda Ciarán Byrne gave evidence at the trials at the Special Criminal Court about the gathering of footage throughout south Dublin relating to that day.

Each piece of footage was analysed by detectives frame by frame, and evidence relevant to the movement of the cars was accepted by the court as evidence relating to the murder.

Two other cars were also of importance – a Ford Fiesta and a Mitsubishi Mirage. Both of those cars were moving around the south city at pertinent times.

Shortly before 10am that morning, some six hours before the murder, the Ford Fiesta had escorted the stolen Suzuki from the Dublin 6 area towards the south city.

The Suzuki was parked up close to the Grand Canal, as was the stolen Mercedes.

An important piece of evidence in the case related to something that would have seemed so innocuous to passers-by that day.

The criminal cell responsible for the murder of Mr Douglas had to pay parking meters a number of times during the day.

This was so as not arouse any suspicion about the vehicles, and to ensure that the cars were not clamped before they could be used later that day in the murder plot.

A few minutes before 4pm that afternoon, the two stolen cars were "activated" and began making their way into the south inner city.

The gang must have known that there was a possibility that Mr Douglas’ wife or daughter might also be present in the shop.

On that day, it was his teenage daughter who was with her father. And it was she who raised the alarm just after 4.11pm that day.

The murder necessarily involved careful preparation. But it also required a debrief and cover-up, Chief Superintendent Paul Cleary told Prime Time.

Among the pieces of evidence gathered by investigating gardaí was footage of Mr Thompson and Mr Canavan going out for a meal in Dublin city just three hours after the murder.

Chief Supt Cleary said that gardaí believe that the two murderers would have used this an an opportunity to debrief.

The footage is chilling because it is so ordinary.

Once again, those passing by would have been none the wiser as to who the men were or what they had been involved in earlier that day.

During the trials of Mr Thompson and Mr Canavan, the Special Criminal Court accepted the evidence of gardaí who said they could recognise both men on the CCTV footage acquired as part of the investigation.

Gardaí such as Garda Patrick McAvinue, Detective Garda Séamus O’Donovan and Detective Sergeant Adrian Whitelaw all independently gave "recognition" evidence.

Mr Thompson was known to gardaí for many years. After the murder of Mr Douglas, he had fled abroad.

But in November 2016, five months after the murder, detectives became aware that Mr Thompson was back on the island, having flown in through Belfast.

Chief Supt Cleary said that he had received intelligence that Mr Thompson would be returning briefly for a gangland meeting at a hotel in north Dublin.

The so-called "murder car" had been discovered close to the scene of the crime

Mr Thompson, surprised to see Chief Supt Cleary and his team at the hotel, entered the gent’s toilets in the hotel.

"I followed him and informed him I was arresting him for the murder of David Douglas," Chief Supt Cleary told Prime Time.

Three days after Mr Douglas was shot dead, two of the gang went to Sandymount where the Suzuki had been abandoned after the murder.

It’s possible that, at the "debrief" in the restaurant on the night of the murder, it had been discussed that the swap car should be destroyed.

On the night of Monday 4 July, an attempt was made to set the car alight, but passers-by intervened. The attempt by the gang to destroy the car and any forensic evidence within it was unsuccessful.

A short time later, Mr Canavan, who was travelling in the passenger seat of a car elsewhere in south Dublin, was arrested. There was a smell of petrol in the car.

The discovery of the swap car helped gardaí to work backwards from the murder car, which had been burnt out close to the scene of the crime.

In its judgment last week, the Special Criminal Court noted that, based on garda information, Mr Canavan had been linked to 22 different vehicles, either as a driver or passenger.

The court found him guilty of both the murder of Mr Douglas and of causing criminal damage to the Suzuki Swift swap car.

Investigating gardaí received "very good co-operation" from people in the area

Due to the Covid-19 pandemic and related health concerns for Mr Canavan, he was not physically present in court. He joined the proceedings by video-link from prison.

He will be sentenced next month, when he can expect to receive the mandatory sentence of life imprisonment for murder.

Mr Douglas was murdered at the height of what has been termed the "Hutch-Kinahan feud".

He was a soft target, and his murder left his family bereft, and traumatised many people in the south inner city. The gang responsible not only came from the local area, but used their local know-how of the roads to plot and plan a murder.

That they were caught on camera and brought to justice is significant.

"You’ve got a minority of people involved in serious crime and bring fear into an area in relation to these types of gangland murders," said Detective Superintendent Peter O’Boyle, who spent many years policing the south inner city.

"We’ve found that, in the past, intimidation can be a factor. In this case, we did receive very very good co-operation from the people of the south inner city."
