THE jury in the trial of Graham Dwyer has been shown CCTV footage which the prosecuation claims shows the architect calling to Elaine O'Hara's apartment complex nine times - including one visit which happened a week before she disappeared.
Among the footage played back to the Central Criminal Court was a brief clip of Mr Dwyer and Ms O'Hara arriving together in the lobby of the building before taking the lift.
Mr Dwyer (42), of Kerrymount Close, Foxrock, is pleading not guilty to the murder of Ms O'Hara (36) at Killakee, Rathfarnham on August 22, 2012.
Ms O'Hara, a childcare assistant from Killiney, was last seen alive near Shanganagh Cemetery in Shankill.
Her remains were found by a dog walker in undergrowth in the Dublin mountains on September 13, 2013.
The footage from Belarmine Plaza, Stepaside was dated between January and August 2012 and was shown to the jury by Det Sgt Kevin Duggan.
It showed Mr Dwyer entering the lobby, taking either the lift or stairway up, and leaving after times ranging from a minute to just under an hour and 15 minutes.
Mr Dwyer, in a dark suit, white shirt, red tie and wearing glasses, watched the video from a monitor in front of him while it was also played back on larger screens, visible to all in the court including Ms O'Hara's father who sat in the public gallery.
The first clip was dated January 21, 2012 when Ms O'Hara was seen leaving the apartment at 9.19am that morning. Mr Dwyer was seen arriving at 2.17pm and leaving ten minutes later. She returned at 4.57pm.

Det Sgt Duggan told prosecution counsel Sean Guerin SC that in that clip, Mr Dwyer appeared to have a phone in his hand before putting it away and taking a second phone out of his pocket, then getting in the lift.
On August 13, 2012, Ms O'Hara was seen entering at 8.43am, then letting in a tradesman at 10.15am. The tradesman left at 11.11am and she left carrying bags at 12.38pm, with Mr Dwyer arriving at 8.02pm and leaving ten minutes later with a red and black rucksack on his back.
The final clip of Mr Dwyer at Belarmine Plaza was taken on August 15, when he entered at 7pm carrying the backpack. Ms O'Hara returned home at 7.36pm and he left at 8.02pm carrying the bag.
The jury was shown a close-up of the backpack, as well as a photograph of a muddy black and red backpack which had been retrieved from Vartry reservoir in Co Wicklow.
