Graham Dwyer’s sister has given evidence in her brother’s trial.

The Dublin architect is accused of murdering childcare worker Elaine O’Hara in the Dublin Mountains in August 2012.

Mandy Wroblewski was the third prosecution witness called on Day 20 of her brother’s trial.

She was asked about an 083 number that the jury previously heard was used to text Elaine O’Hara in the lead up to her death.

She said she did not recognise the number and was then asked if it would have been common for her to receive communication by post from him.

She said she would receive birthday cards for herself, her husband and their children.

In her statement to gardaí, she said he would often write down her address as Oak Lawn or just Oak instead of Oak Park.

Day 15 of the trial heard about the purchase of a phone by somebody called Goroon Caisholn who gave an address at: Oak Lawn, Clerihan, Co Tipperary

She finished her evidence by telling the court she did not know anybody by that name.

Separately today the court heard that a document outlining an apparent contract between a BDSM master and slave was found on Elaine O’Hara’s laptop.

The trial has also heard that downloaded images of mutilated bodies were found on her computer after she went missing.

A number of images of Elaine O'Hara herself were also found - some self taken, others by a different person.

Detective Garda Brid Wallace also explained that Ms O'Hara was clothed in some of the images, and in others was either unclothed or partially clothed. 

Graham Dwyer denies murdering the childcare worker to satisfy his own sexual fantasies in the Dublin Mountains in August 2012.
