Murder of criminal may trigger a spate of revenge killings
In the past month, five people have died in unlinked gangland feuding. Gilligan was shot 48 hours after Sligo man Hughie McGinley, 26, was gunned down in a van in Sligo. His death is associated with feuding between two local families.
Gilligan, 30, originally from Fortlawn Drive, Clonsilla, had been living with his partner and children at Huntstown Wood, a housing estate near Clonee village on the Dublin/Meath border.
