Det Gda Thomas Kilcoyne joined An Garda Síochána in September 1983. He was stationed at Lifford, Co Donegal, when White was moved there in 1995. He was appointed a detective in 1997.
According to his own evidence, Kilcoyne was "totally inexperienced" and White taught him how to conduct an investigation.
He was with White when he planted a sawn-off shotgun at a Traveller encampment at Burnfoot, Co Donegal, in May 1998.
Following pangs of conscience and rumours in the force about what went on at Burnfoot, Kilcoyne gave a statement in 2001 saying that the gun was planted and admitting his part in it.
The tribunal found Kilcoyne stood as "a good example of an officer who, had he not come under the bad influence of Det Sgt White, might well have served within An Garda Síochána without serious blemish".
The fact that he told the truth, very much against his best interests, shows that decency is, and always was, the foundation of his character.
WHAT THE TRIBUNAL SAID: "It is shocking that a man like that can be inveigled into a criminal conspiracy."
