Peter Clinton, 25, has been found guilty of murder after stabbing his friend 5 times in the chest. He denied killing Scott Cooke in December 2011, claiming that he acted in self-defence.
Damen McDonough, 24, was cleared of murder but found guilty of manslaughter.
Aaron Doran, 25, was cleared of both murder and manslaughter.
The trio stole electrical goods from a friend of Mr Cooke, Mark Williams, hours before the murder, and had all already been found guilty of aggravated burglary.
Doran was sentenced to 12 months in prison. Clinton and McDonough will be sentenced today.
