Gardaí have released a man arrested in connection with the 1995 disappearance of Jo Jo Dullard, who vanished while hitchhiking home to Kilkenny. The investigation, now a murder inquiry, has prompted ongoing searches in Co Wicklow. Authorities are specifically looking for human remains and personal belongings linked to Dullard, last seen in Moone. Despite speculation of a serial killer in similar cases, police do not believe this applies here. The public is urged to assist with any information that may help solve this longstanding mystery.
