He was a volunteer in the Loyalist Volunteer Force (LVF), the paramilitary organisation founded in 1996 by Billy Wright and later commanded by his brother Mark "Swinger" Fulton until the latter's death in 2002. He was convicted in 2006 of LVF-related crimes; these included having ordered the murder of a local Portadown woman and seven attempted murders. Fulton was sentenced to life in prison. His trial was the longest in the legal history of Northern Ireland.
