Jury finds Mountjoy prisoner guilty of murdering fellow inmate
Summary
A jury at the Central Criminal Court found 40‑year‑old David Dunne guilty of murder after he lured fellow inmate Robert O'Connor into his cell, knocked him to the ground and stamped on his head in a "vicious and unprovoked" assault. The verdict, reached in just under three hours, was unanimous. Dunne had pleaded not guilty, claiming he had no intention to kill and that he acted in self‑defence after O'Connor punched him twice. The prosecution presented CCTV footage showing Dunne and three other prisoners entering the cell, with officers later reporting that Dunne stamped on O'Connor's head more than once and kicked him. A pathologist's report confirmed that the blows caused brain rotation and tearing of nerve cells, consistent with stamping, punching or kicking. Dunne will face a mandatory life sentence when he is sentenced on 16 December.
