Noon: Elaine O'Hara (36) is released from St Edmundsbury Hospital in Lucan, a psychiatric unit where she has been a voluntary patient since July 14th. Graham Dwyer is in contact with her via texts, and instructs her to meet him that evening for "punishment" at a place he has selected in the Dublin mountains.

She visits her father Frank O’Hara and her niece in Killiney and they visit her mother’s grave at Shanganagh Cemetery.

5.05pm: O'Hara is captured on CCTV driving out of Belarmine.

5.45pm: O'Hara is last seen by a jogger, Conor Guilfoyle, crossing the railway bridge at Shanganagh Park, close to the cemetery.

6pm to 9.15pm: Dwyer's work phone is switched off. He has taken O'Hara to Killakee mountain and murdered her, disposing of her belongings at the Vartry reservoir then or some time later.
