FILES on Elaine O’Hara’s computer contained information on different ways of killing people, including use of weapons and methods of “picking a target,” the Central Criminal Court has heard.
The documents were retrieved from the hard drive of Ms O’Hara’s laptop by gardai investigating her disappearance and death.
The jury in the trial of Graham Dwyer was told of their discovery by Detective Garda Brid Wallace from the computer crime unit.
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 that day.
Her remains were found by a dog walker in undergrowth in the Dublin mountains on September 13, 2013.
The prosecution maintains Mr Dwyer killed her for his own sexual gratification.
Resuming evidence from yesterday, Det Gda Wallace told Sean Guerin SC, prosecuting, that one of the files found on the computer was an image file put together for her counsellor, called “Pictures For Stuart.”
This contained pictures of Ms O’Hara and members of her family, was created in July 2010 and last modified in January 2011.
Another file called “Help Me Learn” was a jpeg, or image file and Det Gda Wallace said she was aware that this was the profile name Ms O’Hara had used on the Alt.com adult website.
The image was of a “long-haired and bearded male.”
The date of the file was September 1, 2010 and it was last accessed on August 18, 2012.
Det Gda Wallace agreed that this was the date a lot of the files were last accessed.
In the Downloads folder, in a subfolder entitled “Read This,” three PDF-type documents were found.
The first was “21 techniques.pdf”.
“It appears to be a publication or book called 21 Techniques for silent killing,” Mr Guerin said, adding that it was by a Master Hei Long and published in Colorado.
It had four chapters titled “Manual Weapons”, “Spike”, “Knife” and “Nunchaku”.
There was another document in the same folder called “Hidden Weapons.pdf”.
This was a 35-page document or booklet with accounts of various weapons listed in the contents.
Another document was called “Murder Inc the book.pdf” by “Jack the Rippa”. This had 62 pages and the table of contents included “Chapter1: The Mark”, “Chapter 2: Unarmed kills”, “Chapter 3: Edged and piercing kills”, and another chapter entitled “Gun kills.”
Mr Guerin said this went on to identify “a number of different ways of killing people and identifies methods for picking a target and various ways to kill people.”
Det Gda Wallace agreed.
The last access to this document was August 18, 2012.
Det Sgt Wallace agreed that a file on the desktop called “SpecialEd2” had been created and in it was a file called dyslexiaandreading.doc, which contained a four-page essay or assignment on reading and dyslexia with children who have difficulty reading skills.
The court heard the file was created and modified on November 29, 2011, and the name of the author in the last modified record was “AD Wejchert”.
“That would be the profile name of the person who was logged on to the computer,” she told the court.
The detective also examined communication sent to and from Ms O’Hara through Yahoo messenger, which she said allows real-time chat between users who had downloaded the software and created a profile.
Ms O’Hara’s profile name was “Bound” and her email was firstname.lastname@example.org, which she used when in contact with three other profile users between September 15 and November 4, 2010.
The court heard Ms O’Hara was first in contact with a man named Deepak, and they had two chat sessions on the evenings of September 15 and 18, 2010.
Det Sgt Wallace agreed with Mr Guerin that the man had indicated he had uploaded a picture of himself to Alt.com, but a face was not in it
Ms O’Hara indicated she had been on that side and there was also a discussion about another adult site, collarme.com.
“I didn’t find any indication to say Ms O’Hara had logged on to that,” Det Sgt Wallace said.
The pair discussed sexual and bondage activity in the chat messages, personal information about work, and how Ms O’Hara was looking for a mask.
Mr Guerin said the second profile Ms O’Hara was in touch with was Kurt Ronnhuist, who he said had already given evidence in court.
They chatted on the night of September 21, 2010 and discussed meeting up and discussed using a sleeping bag or duvet as a form of punishment, Mr Guerin said.
They chatted again two nights later and discussed BDSM activity and meeting neat Grafton Street the following Saturday afternoon.
A third communication, on September 25, was “mostly about the question of interior decoration of Ms O’Hara’s apartment” and did not include sexual or BDSM contact, he said.
The court heard the third set of chat messages were from a man who said he was a solicitor and used the email Roleplay@hotmail.com, and the profile name MasterWilliam.
In the first message, on October 4, 2010, he sent an image and “indicated what he expects from a slave”, including a list of things he’d like her to do if they met, Mr Guerin said.
“There was a discussion about meeting in Dundrum the following week but that conversation ends without arrangement to meet,” he added.
In their online chat, Ms O’Hara asked “MasterWilliam” what he did for a living and he replied that he was a solicitor. It appeared from the conversation that she had sent him an image of herself.
There was then a discussion about meeting in Dundrum the following week but arrangements were not made and they agreed to talk about it again.
There were also text messages or excerpts of text messages with a person called William in late June, 2011.
This indicated that the other person had been away and there was a discussion about whether he had been back or not.
There was a discussion about “meeting again” which suggested that they had met previously. There was another discussion about meeting later in July but it was not clear whether they actually did or not.
There was subsequent communication with someone called William but on this occasion, a different phone number was used.
There was a discussion in late October 2011 about the weather and Dundrum Shopping Centre having suffered badly because of it.
The conversation was general but there was a reference in a message apparently sent by Ms O’Hara to “her master.”
Det Gda Wallace said she filtered internet activity related to Alt.com and found evidence that Ms O'Hara had been a member of the site with the profile HelpMeLearn. The profile picture was one that had previously been shown to the court, Det Gda Wallace said.
She looked at web page preview images and some of those related to online searches using search engines like Google.
Keyword searches were found for the adult site fetlife.com dating from November 17, 2010, but none for the collarme.com site.
She found traces of chats between Ms O’Hara and profiles on Alt.com. One was “Kinkyswitch38@yahoo.co.uk.”
Ms O’Hara appeared to be addressing the other person as “sir.”
There were trace messages that appeared to show she was trying to send a document to the other person. Trace chats were found with two other names as well, Det Gda Wallace agreed
She then examined email communications related to Ms O’Hara’s email@example.com address.
Mails were found from a website extremerestraints.com which were responses to password requests by Ms O’Hara, as well as confirmation of orders.
“They appeared to be sexually-related paraphernalia she had placed orders for,” Det Gda Wallace told Mr Guerin.
The address was Ardmeen Lodge in Blackrock, one of Ms O’Hara’s previous addresses.
There was also a series of emails to and from the Tall Ships Festival including an update for volunteers.
Det Gda Wallace also examined a blue Compaq computer and was able to identify that Ms O’Hara had visited the Alt.com site using it. She examined web pages visited and the profile name DublinMaster featured as one she had viewed on that computer.
The trial continues before Mr Justice Tony Hunt and a jury of seven men and five women.
