Tragic Jennie Poole's brutal killer attacked a prison officer in Mountjoy Prison, we can reveal.
Evil Gavin Murphy was thrown in an isolated padded cell for three days as punishment after the attempted assault. It is understood the brave warder involved was not seriously hurt.
Murphy, 30, originally from Ballymun in Dublin, has a long history of violence and was previously in trouble while on remand while awaiting trial for Jenny’s murder in Cloverhill Prison.
