His trial also heard Mr Dwyer’s car travelled from Galway to Dublin at the same time an unattributed mobile phone, in the case, had been used on the same day on that route.
However, under cross-examination by Remy Farrell, defending, a Garda witness confirmed the times text messages had been sent were not available from the billing information.
At the Central Criminal Court, a female friend said she broke off contact with Ms O’Hara due to constant calls and text messages.
“I found it too much,” Elaine Twomey stated. “I deleted her number from my mobile phone.”
Ms Twomey, who had known Ms O’Hara for 10 years, said the deceased had told her that she would go on to adult websites to meet men for sex. She stated Ms O’Hara had said she enjoyed being tied up and cut by men, and that she enjoyed the release of blood from her body as it would release the tension she was feeling.
The witness also said her friend enjoyed self-harming.
She said that the deceased would have mood swings and become depressed. Ms O’Hara once showed her she had cut her stomach with a knife, but Ms Twomey described the wounds as nicks and not deep.
Ms Twomey said her friend had suicidal tendencies but never said how she would do it.
Ms O’Hara had told her she had been seeing a bisexual man called Adam, who did not cut her or tie her up.
Ms O’Hara also told her she had had a miscarriage at two or three months. The witness said Ms O’Hara was sad and disgusted with herself after losing her child. She said her friend also said Adam was the father, but that she had never told him. She said she had also not told her doctor. “In my opinion, there was no relationship there, just sex,” she stated of Ms O’Hara’s relationship with that man.
Ms Twomey said that she had severed contact with Ms O’Hara in the summer of 2012 after her friend had started to phone and text her constantly.
Mr Dwyer, aged 42, of Kerrymount Close, Foxrock, Dublin, is charged with the murder of Dubliner Ms O’Hara, aged 36, at Killakee, Rathfarnham, on August 22, 2012.
The Cork-born father of three has pleaded not guilty to murdering the childcare worker on that date.
Garda Paul Kane testified he had received phone bills for Mr Dwyer’s work phone as part of the investigation.
He analysed the bills to ascertain if Mr Dwyer had made calls or sent text messages to the number he had for Ms O’Hara.
He found communication to Ms O’Hara from January 15, 2008, to December 4, 2009.
The witness said there were 847 text messages from Mr Dwyer to Ms O’Hara and one voice call directly into her message minder during that time.
He confirmed that neither he nor anybody else was able to document the content of these messages.
He gave evidence of the number of text messages sent to Ms O’Hara on several dates.
These included 14 on the first day of documented contact, 22 on January 17, 2008, and 24 on October 3 that year, as well as 53 on January 13, 2009.
Under cross-examination, Garda Kane said the times the text messages had been sent were not available from the billing information.
