Five people will be sentenced in April in connection with the murder of 61-year-old grandmother, Patricia O'Connor.

Ms O'Connor was killed in May 2017, in the bathroom of her home in Rathfarnham by her daughter's partner, Kieran Greene, who dismembered her and scattered her body around the Wicklow mountains.

Ms O'Connor's husband, daughter, granddaughter and her granddaughter's father have now been convicted of trying to cover up what happened, with the jury bringing in their final verdict today in relation to Keith Johnston.

Johnston, 43, was the former partner of Patricia O'Connor's daughter Louise. He was father to Louise's two eldest children and was described as a "trusted member of the family".

He would often help out with DIY jobs around the house, despite no longer being in a relationship with Louise.

On 9 June 2017, more than a week after Ms O'Connor had been murdered, he went on a "shopping spree" with Kieran Greene to local DIY shops. Greene bought items including, hacksaws, axes and black bags. Gardaí put it to Johnston that Greene bought the "exact tools" needed to chop up a body.

Johnston described the gardaí as lying swines. He said he did not put two and two together and did not know these items would be used in dismembering Ms O'Connor's body.

But the prosecution said this was unbelievable and the jury agreed, unanimously, finding him guilty of impeding Greene's apprehension or prosecution at the end of deliberations lasting more than 12 hours.

Johnston will be sentenced after a hearing on 20 April along with Louise, her daughter Stephanie, and Ms O'Connor's husband Gus who were also convicted of the cover up.

The jury found Louise and Stephanie were involved in a plan to pretend Ms O'Connor had stormed out of the house with a suitcase when they knew she had been murdered.

Gus O'Connor pleaded guilty shortly before the trial began to reporting his estranged wife missing, knowing she was dead and that Greene had killed her.

Greene himself will be given the mandatory sentence of life in prison.

The sentence hearing is likely to hear victim impact evidence from Ms O'Connor's brothers and sisters and her son, Richard.
