A 16-year-old boy who was involved in a row outside a house in Cork during which a student was stabbed to death last year has been sentenced to two years' detention with a further two years' supervision.

The boy, who was 14 at the time, is one of three teenagers who have been convicted in connection with the death of Cameron Blair at a house party in Cork on 16 January 2020.

He pleaded guilty to violent disorder.

Mr Justice David Keane said today the killing of Cameron was "an indescribable tragedy" exacerbated by "senselessness of the violence".

Cameron was a sportsman, a rugby player, a second-year student and a black belt in Karate.

The 20-year-old went to a student party at a house on the Bandon Road in Cork on 16 January last year and agreed to watch the door.

The 14-year-old boy arrived with two older teenagers and a drunk homeless man and although the others in the house did not want to admit them, Cameron said they were "sound" and let them in.

The homeless man fell asleep outside in a doorway but Cameron became concerned and brought him in also.

The three teenagers drank inside with the students but a row broke out outside later after they had been asked to leave.

The teenagers tried to get back in and the 14-year-old boy, who was the youngest of the three, had armed himself with a butter knife and punched a girl in the eye.

Cameron was at the door at the time when he was attacked and stabbed in the neck by a 17-year-old boy.

He has already been sentenced to detention for life with a direction that he must serve a minimum of 13 years with a review in November 2032.

Another teenager has been jailed for two years for violent disorder and production of a knife.

Two other men have been jailed for contempt of court for not turning up to give evidence.

The 14-year-old boy said he had drank vodka from a bowl that night because there were no glasses or cups left and claimed his memory of the events that night are "a bit hazy" although he does get "flashbacks".

But Mr Justice Keane said that he did not accept his lapses of memory and it was clear that the boy still does not accept the gravity of the offence and the impact it has had on others.

The judge said the boy does not even know how his behaviour could have "fuelled" the subsequent consequences for Cameron Blair.

Having witnessed the attack, the judge said, the boy left, returned and fled again, he did not offer any assistance or remain. His threats were part of "calculated and deliberate" actions.

The students including Cameron, he said, had showed the three "kindness and indulgence" at the time.

He sentenced the boy to two years' detention and two further years' supervision by the probation service.

The judge also expressed his sympathies to Cameron's family on the "irreplaceable loss of an exemplary young man".

Cameron's loss left an emptiness 'that cannot be filled'

Cameron's family has said the violence associated with knife crime has to stop.

Speaking outside the Central Criminal Court following today's sentencing hearing, Cameron's uncle, Aidan Donnelly, said that every time the family hears about another innocent victim being attacked or murdered with a knife "it affects us immensely."

"What family will be next to get the dreaded phone call?" he asked, "this has to stop."

As a parent, he said, you pray each night that no harm will come to your children and that they will not cross paths with people who are armed with knives and are violent.

He said Cameron always had a positive attitude and always urged people to, in his words, "keep driving it on."

He said the loss of Cameron has left an emptiness in their world that cannot be filled but, the family will try to honour his memory by living the best life that they can.
