MURDERED grandmother Patricia O'Connor's daughter has been found guilty of impeding her killer Kieran Greene's prosecution.
Louise O'Connor (41) agreed to her own daughter Stephanie disguising herself as Patricia in a "ruse" to cover up the fact that Greene, Louise's then-partner, had murdered her.
She did not react as the jury delivered its unanimous verdict at the Central Criminal Court this afternoon.
Deliberations will continue tomorrow in the case of Louise's ex-partner Keith Johnston (43), who is accused of impeding Greene's prosecution by helping him after the killing to buy tools "to deploy in the concealment" of Patricia's remains.
Greene (35) beat the grandmother-of-seven to death in a row at the family home at Mountainview Park, Rathfarnham on May 29, 2017.
He buried her body in a shallow grave, then dug it up 10 days later, dismembered it with a hacksaw and scattered the remains in the Wicklow mountains.
On Tuesday, the jury found Greene guilty of murder. Yesterday, Louise and Mr Johnston's daughter Stephanie O'Connor (22) was convicted of impeding Greene's prosecution by dressing up as her dead grandmother on the night of the murder.
The jury had heard this was so she would be captured on a neighbour's CCTV, to create the illusion that Patricia (61) was still alive and bolster any claims that she was missing.
They all pleaded not guilty.
This afternoon, after 11 hours and 17 minutes of deliberations so far, the jury returned and was asked if a verdict had been reached in Mr Johnston's case.
The forewoman replied "no" and Mr Justice Paul McDermott told them to suspend deliberations and return to court in the morning.
Earlier the court registrar asked the forewoman if the jury had reached a verdict in Louise O'Connor's case. She replied that they had and confirmed the verdict was guilty.
Louise O'Connor, wearing a large black coat with a fur lined hood and a pink and grey-patterned scarf sat with her head down as the jury filed in, but looked up at them as they took their seats.
She glanced from the jury towards the judge and back as the verdict was read out, but showed no reaction.
Mr Johnston has already been acquitted by direction of the judge of a second count alleging that he refurbished the bathroom where Patricia was killed to conceal evidence.
Before the trial started, Patricia's husband Gus O'Connor pleaded guilty to impeding Greene's prosecution by falsely reporting Patricia missing on June 1, when he knew she was dead.
