In a statement, the family of Chris McManus described the overwhelming feelings of trauma and pain when they were told of his death.
"We accept that the decisions reached and taken by the authorities were the only ones possible based on the information available.
"Two years ago we lost our beloved Chris, the trauma, pain, horror and distress have been overwhelming and intense. We are living our way through the grief with the tireless support and love of our family and friends. Our thanks and love goes out to each and every one of them.
"Chris cannot be hurt any more; we and all those who loved him will always remember the way he lived and not the way he died."
The pathologist who carried out the post-mortem found that in addition to head wounds, Christopher McManus also suffered injuries to the left leg, the left arm and torso. One section of the report read:
Death would have followed rapidly if not immediately... There would have been nothing a medical responder, however promptly they had been on the scene, could have done to save his life.
