The jury has begun its deliberations in the trial of a man accused of murdering a grandmother of seven whose remains were found scattered across the Dublin and Wicklow mountains nearly three years ago.

Kieran Greene, aged 35, has pleaded not guilty to the murder of Patricia O'Connor at her home in Mountainview Park in Rathfarnham on 29 May 2017.

The jury is considering verdicts against a total of four defendants who have been charged in connection with the death of the 61-year-old.

The deceased's 41-year-old daughter Louise O'Connor; her granddaughter Stephanie O'Connor, aged 22, both of Millmount Court, Dundrum Road, in Dublin 14, along with Louise O'Connor's 43-year-old former partner Keith Johnston, of Avonbeg Gardens, in Tallaght, are accused of impeding the apprehension or prosecution of Mr Greene, knowing or believing him to have committed an arrestable offence.

Concluding his charge to the jury, Mr Justice Paul McDermott told the 11 members that they must return unanimous verdicts. One woman was discharged from the panel over the weekend because she could not continue with the case.

The six-week trial heard that the body of Patricia O'Connor's had been dismembered into 15 separate parts.

These were found at nine different locations over a 30km area in the Dublin and Wicklow mountains over several days in June 2017.

Former Deputy State Pathologist, Dr Michael Curtis, gave evidence that the victim's head had been struck at least three times with a solid implement.

He said the cause of death was blunt force trauma to the head.

After deliberating for just under two hours, the 11-member jury in the trial has been sent home for the night.
