The Graham Dwyer trial has heard that gardaí showed his adult son CCTV stills from Elaine O’Hara’s apartment block to see whether he could identify anyone in the footage.
The stills showed a man that the prosecution had already identified as the architect accused of Ms O’Hara’s murder.
The Central Criminal Court was hearing from the garda concerned today on the 10th day of the 42-year-old’s trial.
Mr Dwyer is charged with Ms O’Hara’s murder in the Dublin Mountains at Killakee, Rathfarnham on August 22nd, 2012, hours after she was discharged from a mental health hospital.
The Cork-born father of three of Kerrymount Close, Foxrock, Dublin has pleaded not guilty to murdering the 36-year-old childcare worker on that date.
Footage from her apartment block at Belarmine Plaza, Stepaside was shown to the jury yesterday. In it, a garda identified nine occasions when Mr Dwyer was present, including once with Ms O’Hara.
A still from the footage, apparently showing him carrying a backpack, was shown alongside a photograph of a bag recovered from a Wicklow lake as part of the investigation into her death.
Detective Garda Paul Corcoran testified this morning that on October 18, 2013, he showed stills from the footage to Sennan McShea.
“We were aware that Sennan McShea was the son of Mr Dwyer and the purpose was to see if he could identify anybody in the footage,” he explained.
The detective identified three stills signed by Mr McShea, who was over 18 at the time.
“He would have seen all the stills in the booklet and would have selected the ones he was confident with,” he said.
The jury also heard from Garda Keith Gantly this morning. He said he had conducted inquiries about CCTV in the Shangannah area in the aftermath of Ms O’Hara’s disappearance.
The court had already heard that she was last seen there on the evening of August 22, 2012 and that her car was later found there.
He said that there was only one camera working in the immediate area at the time and that it was pointing in the wrong direction. He said that there was also no footage of assistance in nearby Shankill Village.
The trial has heard that Ms O’Hara’s skeletal remains were discovered at Killakee on Friday, September 13, 2013. A cause of death could not be determined.
The jury heard that glasses found in a Vartry Reservoir a few weeks later matched her prescription and frames, and that keys to her home and car were also found in the lake.
The trial continues before Mr Justice Tony Hunt and a jury of five women and seven men.
