Mr Carey, who had been using the hotel gym at the time of the attack, died the following August.
At least two men chased Mr Carey through the car park before shooting him six times in the chest and arm.
He was brought to nearby St James’s Hospital for treatment. He had lost a large amount of blood but was conscious following the attack.
Although initially expected to recover from his injuries, Mr Carey developed an infection and he died in hospital.
It was the third time he had been targeted in a shooting attack in a two-year period and he had spent time outside the country due to fears for his safety.
