The killing of IRA man Séamus Bradley who was shot by a British soldier as he ran across a field in Derry in 1972 was unjustified, a coroner has ruled.
The shooting of Séamus Bradley, who was 19 at the time, has long been a matter of dispute.
He was killed by soldiers from the Royal Scots Regiment during Operation Motorman - a British Army attempt to gain control of republican areas in Belfast and Derry that had previously been considered no-go zones for the security forces.
The Army claimed the teenager was shot while he was in a tree and suffered additional injuries as he fell.
His family alleged he was killed later, claiming he was taken away in an Army Saracen vehicle and alleging he sustained fatal injuries while being subjected to interrogation.
Judge Patrick Kinney rejected both those versions of events as he ruled at Belfast Coroner's Court.
He said he was satisfied Mr Bradley was killed by a soldier who got out of a Saracen vehicle, dropped to one knee and opened fire, adding that he had not been able to confirm the identity of the soldier who fired the shots.
He also said Mr Bradley was not posing a threat.
"He was running across an open area of ground, he had no weapon and he was clearly visible," he said.
The coroner added: "The use of force by the solder was entirely disproportionate to any threat that might have been perceived."
