Gardaí have launched a major excavation at a disused quarry in Castleruddery Upper, Co Wicklow in the search for Josephine “Jo Jo” Dullard and Deirdre Jacob. The search was triggered by a new witness statement described as “very specific” and “credible”, pinpointing an exact burial location within the extensive quarry site. Stephen Breen, Crime Editor with The Irish Sun, joins Emmet Oliver to discuss.
