Cameron Blair's 'boyish smile and joy of life' recalled by friends in moving tributes

Update 2pm: Cameron Blair was recalled by those in Bandon and beyond as someone whose sporting prowess was matched by his "boyish smile and joy of life", taken in what was described by a Bishop as "every parent's worst nightmare".

The 20-year-old from Ballinascarty was remembered by his former schools and sports clubs, as many struggled to comprehend the brutal circumstances of his death on Thursday night in Cork City.

The second-year CIT student had attended two secondary schools in Bandon and had also represented the town's rugby and athletic club with distinction.

From an area close to Pedlar's Cross and Ballinascarty, he attended Bandon Grammar School for four years before completing the Leaving Certificate cycle at Hamilton High School, also in Bandon. His younger brother, Alan, is currently in 5th year in Bandon Grammar.

School Principal Ian Coombes paid tribute to Cameron, who he said had been a brilliant sportsman and also an "extremely bright young man".

"He represented the school in athletics and rugby with great distinction," Mr Coombes said. This included at Munster and all Ireland level, including playing on the Mungret Shield-winning junior rugby team.

"A huge number of our past pupils were very close with him and are very upset, as are our staff members and coaches." He said all the school could do was try and help comfort the family and explain to students how vulnerable they can all be. Mr Coombes said one 5th year had commented today:

"We thought this sort of thing only happened in Dublin."

'They are all horrified and shocked by this," he added. The school cancelled all after school activities in light of Cameron's death.

Bandon Rugby Club Chairman Dan Murphy also paid tribute to Cameron, while the club's Facebook page posted pictures of him in club kit.

"It is with great sadness that we at Bandon Rugby Club learn this morning of the untimely passing of one of our members Cameron Blair," Mr Murphy said. "Such a tragedy will be felt far and wide but will be felt really deeply within our Club where Cameron was a very popular member and current player. Indeed he was scheduled to play with our second team tonight in a league match.

"Cameron’s boyish smile and joy of life left a real indelible mark on anyone he met or any team he played on. He played as he spoke, full of confidence and was a delight to see running a full tilt with a rugby ball.

"Our thoughts, prayers and deepest sympathies are with the Blair and Donnelly families and Cameron’s close friends at this extremely difficult time."

Bandon Athletic Club, where Cameron had been a member, said: "Bandon Athletic Club would like to extend its deepest Sympathies to the Blair family on the passing of Cameron after a tragic incident last night.

"Cameron was a member of the club for a number of years competing at local and national level winning medals at West Cork, County, Munster and National. In 2017 he helped the men's team to a 2nd place finish at the National league promoting them to Premier.

"He will be sorely missed by all who knew him."
