Barry McGrory, 28, was found guilty on Wednesday of stabbing Scots Guardsman Paul McGee to death last October. Anne McGee, 54, yesterday described her son as a "true hero" and said justice had been done following the conviction.
Guardsman McGee, who was decorated for bravery in Iraq, was killed after a night out with his mother, his girlfriend and her mother on 25 October.
He was attacked outside the McGee family home in Lochwinnoch, Renfrewshire, after going to the aid of a taxi driver who was subjected to a road rage assault by co-accused Ian Wallace.
Mrs McGee said: "Paul was a true hero in every sense. He served his country in Iraq and Northern Ireland, only to be murdered back home by pure evil."
