A jury has heard Elaine O'Hara was in extremely good form and looking forward to volunteering at the Tall Ships festival on the day of her death.
Her father Frank O'Hara has been giving evidence at the trial of father-of-two Graham Dwyer, who is charged with the murder of the 36-year-old Dublin childcare worker at Killakee, Rathfarnham on the August 22, 2012.
The jury has heard O'Hara was discharged from St Edmondsbury psychiatric unit on the day she died.
Her father Frank has said she called to his house in Killiney, they had lunch and then went to put flowers on her mother's grave at Shanganagh cemetery.
He said she was in extremely good form - as they parted company at about 4pm she told him she had to be up early the next morning because she was volunteering at the Tall ships festival.
He became concerned over the next two days when he could not contact her and said he even sent a sarcastic text message reading “are you alive?” the following night.
When he discovered that she had not turned up to work at the Tall Ships festival and had not been in contact with St Edmondsbury Hospital he became extremely worried and contacted gardaí.
