Dwyer tried to have all social media images taken offline
Killer Graham Dwyer pleaded with friends to remove all photos and references to him from their social media pages, local websites and club profiles before his murder trial.
It has emerged that Elaine O'Hara's murderer was so determined to limit details about his personal life that he even pleaded with one Cork friend, whose wedding he had attended overseas, to ensure that any photos on Facebook and other sites did not include him.
The friend, who asked to remain anonymous, told the Herald that all such photos were removed from social media sites as a result before the trial proceeded.
Despite this, pictures of the twisted killer with his beloved model planes and attending a scout reunion in his native Bandon still emerged during his high-profile trial.
Dwyer was so paranoid about the possible media coverage of his private life that he spent hours trawling through social media to check what references were still listed about him and contacting friends if there were images that he wanted removed.
So effective was his campaign to erase all traces of his personal life in Bandon and Dublin that even his old school removed his class photo from the wall amid fears that it could be secretly copied. There was no public access to photos of Dwyer at old scout events in Bandon.
While Dwyer spent most of his adult life in Dublin, his close connection with Bandon was underlined by the fact that he chose to celebrate his 40th birthday party in the west Cork town in 2012.
He also travelled back to Bandon for a Munster Arms Hotel reunion dinner for the local scout troop in October 2013.
Days later, Dwyer was arrested on suspicion of the murder of Elaine O'Hara.
To his annoyance, a photo taken of him at the scout reunion appeared in the media.
Since the shocking revelations at the murder trial, many of Dwyer's friends have severed all contact with him.
Dwyer had contacted all his supporters to reassure them of his innocence, and to vow that he will overturn his murder conviction at a Court of Appeal hearing which is likely early this year.
His Cork-based family remain steadfastly loyal and have been visiting him in prison.
Dwyer, of Kerrymount Close, Foxrock, Dublin, was convicted of murdering Ms O'Hara (36) on August 22, 2012.
The skeletal remains of the childcare worker were found on Killakee Mountain, Rathfarnham, Dublin, on September 13, 2013.
After a marathon hearing, the Central Criminal Court jury convicted Dwyer of stabbing Ms O'Hara to death for his own sexual gratification.
He was handed a mandatory life sentence.
His appeal will centre on a number of forensic, evidential and technical issues.
These include how gardai obtained evidence from a bin outside his home, the admission of critical telecommunications data, allowing a key witness to give evidence via video-link, the admissibility of key material obtained from Ms O'Hara's IT devices and the impact of allowing video recordings, some involving violent sexual activity, to be viewed by the jury.
A week after being sentenced, he told prison officers that he would win his appeal and have his name cleared.
