A man and two women questioned after the murder of a grandmother whose dismembered body was found dispersed across the Wicklow Mountains have been released without charge.
Patricia O'Connor (61) and from Rathfarnham, died in May at Mountain View Park in Churchtown in south Dublin.
Files will be prepared for prosecutors after the questioning of a man aged 73 and women aged 19 and 38, gardaí said.
Another man has already been charged.
Ms O'Connor's body was dismembered and dispersed across parts of rural Co Wicklow.
Her remains were recovered over several days along a 20km to 30km stretch of the Old Military Road, with the first gruesome discovery made by a group of people near Glencree Peace and Reconciliation Centre.
Limbs and other parts of the torso were found in other locations, including at Glenmacnass waterfall and at Lough Brea Lower on Military Road, south of Glencree.
Ms O'Connor's head and hands were found in a plastic bag.
