A post-mortem has established that Alex Coughlan, who died after being severely injured in an assault in Blanchardstown last month, suffered "traumatic" head and neck injuries, a court has heard.
Mr Coughlan, who was 37, was found unconscious on 17 May on the Mill Road.
He was brought to the hospital in a critical condition, where he was pronounced dead three days later.
Shortly after he passed away, gardaí charged two boys in connection with the incident.
The boys, aged 16 and 17, are accused of causing serious harm to Mr Coughlan at Mill Road, under section 4 of the Non-Fatal Offences Against the Person Act.
They were also charged with robbing him of his bank cards and a €300 gold ring.
The boys, who cannot be named because they are minors, had been refused bail in the District Court on 20 May, but the younger defendant made a fresh application before Mr Justice Sean Gillane in the High Court in Cloverhill yesterday, which was also denied.
Garda Sergeant Emma Ryan alleged the man was assaulted and robbed of his gold ring, wallet and bank cards at Mill Road, Blanchardstown.
Objecting to bail, Sergeant Ryan said a post-mortem has since been carried out, and the cause of death has been recorded as traumatic head injuries.
Citing the seriousness of the case, she told the court that Mr Coughlan had injuries to his neck area, scrapes to his knees and elbows, which corroborated that he was on his knees pleading with his attacker, and he had "no defensive injuries".
The court heard he suffered severe bruising, and there was evidence of suffocation and choking.
Sergeant Ryan agreed with Keith Branagan BL, for the State, that it was a sustained assault, and footage was available.
The court heard it was an arranged meeting but set up under false pretences for the purpose of committing robbery and extortion offences, and no other motive.
She said Mr Coughlan was walking down the road before the pair blocked him.
A witness reported that Mr Coughlan was on his knees "crying and pleading to the two males".
His AIB and Revolut cards were used in local shops minutes later, and a gold ring given to Mr Coughlan by his father was taken.
She said a file is being prepared for the Director of Public Prosecutions in relation to bringing a more serious charge.
The sergeant agreed with defence counsel Ronan Prendergast BL, instructed by solicitor Brian Keenan, that there were no messages exchanged between his client and the deceased man.
Mr Prendergast submitted that his client, who had been in school, was accompanied to court by his father, who had €1,000 available for a surety.
Counsel said the boy would abide by conditions and engage with a bail supervision scheme linked to the juvenile justice system.
However, Mr Justice Gillane noted the objections and refused bail; he said the boy had to be aware that Mr Coughlan was left "prone, injured and bloodied".
