Sentencing Dunne, Judge Martin Rudland said of Duncan Keating’s death: “Grave consideration has been given between this event, and that tragic death, and the consultant pathologist has concluded his death was due to matters unrelated to the assault.”
Sending him down, the judge told Dunne: “We see from the glaring CCTV footage of the event that you picked on him and you bullied him and you wouldn’t let up.
“You began by using a parasol, then we watch you punch him while he’s lying backwards in a wooden chair in the garden, and you then pursue him round the garden, shouting at him, berating him.
“He is doing nothing but backing away from you at all times, but you goad him, you harass him, you follow him, you try and out-step him and out-manoeuvre him, and when you get close to him you punch him, not once, not twice but three times.
“It was an unpleasant, brazen, bullying event. There is no way you would have behaved as you did to someone who was of your size and strength, and that’s quite apparent from the way in which you teased and goaded him.”
