A man is due to go on trial tomorrow morning, charged with murdering a 61-year-old grandmother, whose remains were found scattered across the Wicklow mountains.

34-year-old Kieran Greene of Mountainview Park, Rathfarnham in Dublin has pleaded not guilty to murdering Patricia O'Connor at the same address on 29 May, 2017.

Mrs O'Connor's daughter, 41-year-old Louise O'Connor of Millmount Court, Dundrum Road in Dublin, her granddaughter, 22-year-old Stephanie O'Connor of the same address and 43-year-old Keith Johnston of Avonbeg Gardens in Tallaght are all charged with impeding the apprehension or prosecution of Mr Greene, knowing or believing him to have murdered Mrs O'Connor.

Louise O'Connor pleaded not guilty to agreeing to or acquiescing in her daughter, Stephanie, disguising herself as Patricia O'Connor at the house in Mountainview Park on 29 May, 2017 in order to conceal the fact that Mrs O'Connor was dead.

Stephanie O'Connor denied disguising herself as her grandmother. 

Mr Johnston pleaded not guilty to assisting Mr Greene in purchasing various implements at Woodies, Mr Price, B&Q and Shoe Zone in Tallaght on 9 June, 2017, to be used in concealing Mrs O'Connor's remains. 

He also denied refurbishing a bathroom at the house at Mountainview Park between 31 May, 2017 and 9 June, 2017 in order to destroy or conceal any evidence relating to the murder of Mrs O'Connor. 

A number of Mrs O'Connor's body parts were discovered dispersed in a 30km area across the Wicklow mountains in June 2017, after she was reported missing.

Mr Justice Michael White told the jury panel that there would be evidence given and references made to the "disinterment and dismemberment of the body parts" of the deceased and warned them that if this presented a difficulty to any one in being a juror to let him know.

Six men and six women were sworn in to hear the trial which will get under way in the morning, before Mr Justice Paul McDermott.

It is due to last between five and seven weeks.
