The husband of a woman whose body was found in 15 different parts in the Wicklow mountains knew she was already dead when he reported her missing to gardaí, the Central Criminal Court has heard.

The trial of Kieran Greene for the murder of Patricia O'Connor has heard that her husband Gus went to gardaí on 1 June 2017 to report her missing.

Mr Greene has denied murdering Mrs O'Connor, who was his girlfriend's mother, on 29 May 2017.

Mrs O'Connor's daughter Louise, granddaughter Stephanie, and her father Keith Johnston have all pleaded not guilty to impeding the apprehension or prosecution of Mr Greene and are on trial with him.

The court has been told that shortly before the trial was due to begin, Gus O'Connor pleaded guilty to impeding the apprehension of an offender by making a false report to gardaí.

Detective Inspector Brian O'Keeffe agreed with defence counsel Conor Devally that in Kieran Greene's first interviews with gardaí in June 2017, he painted himself as being the only participant in the death of Mrs O'Connor, the removal of her body from the scene, and the dismemberment of her remains.

The inspector agreed that nothing in Mr Greene's interviews gave a basis to arrest others. But others, including Gus O'Connor, were arrested on suspicion of murder in early September 2017 after further investigations by gardaí.

The trial has heard that in December that year, Mr Greene - who was in prison awaiting his trial - asked to speak with gardaí, and gave them a different version of what had happened to Mrs O'Connor.

He claimed that Mrs O'Connor had attacked him in the bathroom of the family home with a hurl on the night of 29 May 2017, but that Mr O'Connor had come in to the room and hit her twice with an iron bar or crowbar.

Mr Greene claimed Gus O'Connor told him he was defending him, and that Mr Greene could take the rap for it.

Inspector O'Keeffe agreed that as a result of that interview, an area around the Dodder River was searched and items were recovered, including a hacksaw with hair on it.

He said that if it was not for the new interview with Mr Greene, gardaí would not have searched the area.

A warrant for the re-arrest of Keith Johnston for impeding a prosecution had also been sought as a result of the new interview, he said. He told the court there were no other re-arrests.

Asked if Mr O'Connor had been invited to react to what had been said of him by Mr Greene, the inspector replied that he had been.

Mr O'Connor was charged in October 2018 with reporting Mrs O'Connor missing, knowing she was already dead, and thereby impeding the apprehension of an offender.

The jury was told he pleaded guilty to that offence last month, shortly before this trial began.

The court heard the prosecution’s case has now concluded.

Mr Justice Paul McDermott then heard legal argument and asked the jury to return to court tomorrow afternoon.
