A Dublin murder trial has heard that dental records were used to identify the remains of 61-year-old grandmother Patricia O’Connor.

Her body parts were found scattered across the Dublin and Wicklow Mountains over a four-day period in June 2017.

Kieran Greene denies murdering Patricia O’Connor at her home at Mountainview Park in Rathfarnham, Dublin in May 2017.

In her opening address yesterday, prosecuting barrister Róisín Lacey told the jury it will be alleged that Ms O’Connor suffered fatal head injuries during a violent altercation with Mr Green.

The 34-year-old lived at the house with his girlfriend Louise O'Connor – who is Patricia’s daughter.

Louise O’Connor is also on trial, accused of impeding Mr Greene’s apprehension or prosecution – a charge also faced by her ex-partner Keith Johnston and their daughter Stephanie.

Ms Lacey told the jury they will hear evidence of Mr Greene telling Gardaí he buried the 61-year-old in a shallow grave before dismembering her and scattering her body parts across the Dublin and Wicklow Mountains.

She told the court he later changed his story and blamed two others for killing and dismembering her.

A young woman gave evidence today of stumbling upon a body part while picnicking near the Sally Gap with her family on June 10th, 2017.

Christine Murphy said she thought it was “a piece of a pig.” Her brother Jonathan described it as an upper torso.

Another member of the public gave evidence of finding a body part on a rock near a stream while he and his partner were out for a walk in the area.

A total of 15 body parts were found over a four-day period and the jury heard today that they were identified as belonging to the 61-year-old grandmother through the use of her dental records.
