A 17-year-old boy has been sentenced to seven-and-a-half years' detention for the manslaughter of another teenager in a park in south Dublin last year.
Azzam Raguragui was stabbed to death in Finsbury Park in Dundrum following a "melee" between two groups of youths over a stolen bicycle.
In a victim impact statement, Azzam's father said he will never forget the way his "innocent young boy was tortured, hunted and murdered" before being "left bleeding to death".
Abdul Raguragui was speaking during the sentencing hearing in the Central Criminal Court for the 17-year-old boy who was found guilty of manslaughter.
Azzam's mother Hajiba described the killing as "evil".
Mr Justice Paul McDermott said the 17-year-old boy brought a knife to the scene and used "wholly excessive force". He said the boy produced a knife and stabbed Azzam repeatedly.
The judge said he was not satisfied the boy gave "a full account" of what happened in his prepared statement to gardaí.
He said the boy attacked Azzam "in a most cowardly fashion" as he lay on the ground "in a foetal position".
He made no attempt to get help showing a "callous disregard" for Azzam, the judge said, he attempted to dispose of evidence and told a friend afterwards that he had stabbed the teenager.
However, the judge also said he co-operated with the investigation, helped retrieve the knife, he admitted the stabbing and he was 16 at the time.
The boy he said had expressed regret, but it is difficult to know if he understands the "appalling nature of what he has done" and the devastation he has caused.
He said it was not a case where a non-custodial or limited sentence is open to the court.
Azzam was stabbed five times by the 17-year-old who pleaded "excessive self-defence" and was found not guilty of murder but guilty of manslaughter.
His father told the court that the killing was "committed by a person with no regard for human life".
He said in his victim impact statement that Azzam was "tortured, hunted and murdered" and "left bleeding to death" in the park.
His last words to his son that day he said were "take care of yourself" after they had hugged and kissed.
Mr Raguragui said that the "brightness" had now gone out of their lives.
He added: "His family can visit their son. I take my family to an empty graveyard. I cannot imagine how scared he must have been during that horrifying nightmare."
In her victim impact statement, Azzam's mother described how the family followed the ambulance and when she was allowed in to see her son in the hospital he was "full of blood, from head to toe".
"There was blood everywhere. I never thought I would see him like that," she said. "Who can do that? It's not human, it's evil."
She also asked "why" this had happened. "It's not fair," she said.
"Why? Over a bike? A bike? Something cheap? Seriously?"
This morning, senior counsel Michael Bowman read a statement from the defendant's family in which his mother said her thoughts and prayers were with Azzam's family.
"I know I'll have him back one day," she said of her son.
"I'm sorry they won't get that chance. I pray for them every day. It's a truly heartbreaking situation."
They also said the boy was sorry for what he had done and defence counsel pointed out the boy had told gardaí that he was "so sorry" for what had happened and for Azzam's family".
The court heard the boy was 16 at the time of the killing, that his parents had separated, that they had become homeless and were living in emergency hotel accommodation at the time.
Prosecuting counsel James Dwyer told the court that the boy had been the subject of three juvenile cautions from gardaí, two informal and one formal, which meant he was subject to supervision for 12 months.
The first two were for slapping two boys in a row over an all-weather pitch at a football club in June 2018, while the formal caution was for following and attacking another teenager who was with his girlfriend in Stillorgan in October 2018.
He was under the supervision terms of that formal caution at the time he killed Azzam.
