The convicted sex killer Graham Dwyer could face further garda probes after he is sentenced tomorrow for the murder of Elaine O'Hara.
Dwyer (42) pleaded not guilty to murdering Ms O'Hara, a childcare worker, but a jury found him guilty last month. The married architect from Bandon, Co Cork, is expected to receive a mandatory life sentence at a hearing before Mr Justice Tony Hunt tomorrow. Victim impact statements are expected to be submitted from members of Ms O'Hara's family.
No evidence has emerged to link Dwyer to any unsolved murder or to any of the missing women whose disappearance is being investigated as part of Operation Trace.
However, Dwyer may still be questioned about other serious crimes, such as rapes, given the evidence of his extreme sexual deviancy.
The prosecution claimed that Dwyer planned to kill Ms O'Hara for his own sexual gratification because he was a "sadistic brutal pervert with nothing on his mind other than murder". His trial heard gruesome evidence of his blood lust, including video evidence of him stabbing women, including Ms O'Hara, during sex.
Dwyer's former girlfriend, Emer McShea, gave evidence that he had a stabbing fetish more than 20 years ago, while the images on his computer showed that he had also harboured long-standing fantasies about raping and attacking women.
In text messages to Elaine O'Hara, Dwyer referred to Raonaid Murray, the 17-year-old schoolgirl from Glenageary in south Dublin who was stabbed to death near her home in 1999. He also referred to Eugenia Bratis who was stabbed to death in the Phoenix Park.
Dwyer has reportedly been on suicide watch in Cloverhill Prison where he was placed while awaiting sentencing. He will have 21 days to appeal from the date of his sentencing. He also initiated legal proceedings against the State on January 19 over the manner in which his mobile phone records were accessed by gardai.
