Retired detective says Graham Dwyer would have murdered again after Elaine O'Hara
Graham Dwyer, an architect from Foxrock, south Dublin, was convicted of murdering Elaine O'Hara, a woman aged 36, after stabbing her to death at Killakee Wood in south Dublin in August 2012. Dwyer, whose age is reported as 42 or 53, had a prior BDSM relationship with O'Hara that he rekindled in 2011 before luring her to a meeting near her mother's grave at Shanganagh. He was arrested at his Foxrock home on 17 October 2013, tried at the Central Criminal Court in 2015, and given a mandatory life sentence on 20 April 2015. Dwyer has challenged his conviction up to the Supreme Court without success. In April 2025, retired Detective Sergeant Peter Woods said he believes Dwyer filmed the murder and that Dwyer would have killed again had he not been caught.
