A member of the Fianna, the junior wing of the IRA, he was found lying in his house in the New Lodge area of north Belfast with a bullet wound to the head. He was discovered by a neighbour who had gone to the Allsopp home to visit the boy's mother. On receiving no reply to her knock at the door, the woman entered the house and saw the teenager lying on the ground, his head inside the kitchen, his feet stretched out into the yard. There was no movement and he did not respond to the woman when she spoke to him. An ambulance was called and the boy was taken to hospital where he died.
Detectives who went ot investugate his death were attacked by a crowd, returning later with an army escort. The youth had apparently been shot in the head at close range, police indicating they believed his killing may have been accidental. The gun had been removed from the scene. The teenager's mother told the inquest that she had gone to work that evening leaving him some money to go to a local disco. She was later told that he had been involved in an accident. The police said no weapon was recovered at the house and their appeals for a 13-year-old girl who was seen there around the time of the shooting to come forward went unanswered.
His badly burned body was found in a warehouse on the Antrim Road, next to the home of the SDLP leader, Gerry Fitt. It was reported that he was attempting to burn down the home of the MP, which was attacked on numerous occasions, during rioting which followed the death on hunger strike of Frank Stagg. A detective told and inquest that petrol had been scattered around the warehouse before it was set on fire. He was identified by dental records and two medallions round his neck. According to death notices he was a Fianna staff officer. 'Parlo', as he was known, was from Duncairn Parade, and he is listed in the republican roll of honour as a member of Fianna Eireann. His uncle, Michael Kane, also an IRA member, was killed in a premature explosion in 1970.
