A man with a history of “incredibly sadistic and violent behaviour” has been jailed after gardaí caught him attacking his own mother as she was trying to escort him home.
Blaine O’Mahoney (aged 26) was jailed in December 2005 after he set fire to a homeless man after pouring paint, white spirits and other flammable liquids over him.
Judge Frank O’Donnell sentenced O’Mahoney to 11 years with the final year suspended and commented at the time that without a drastic and radical change O’Mahoney would continue to be a “serious threat to society”.
The 2005 hearing heard that O’Mahoney had pleaded guilty to assault causing serious harm to Mr Richard Hand at a flat on Lower Rathmines Road on August 1, 2003 and assault causing harm to Mr Damian Murphy at Leinster Cricket Club, Rathmines on June 19, 2003.
O’Mahoney also pleaded guilty to robbery of Mr Anthony Hicks at Camden Place, Dublin 2 on August 1, 2004.
Mr Hand suffered severe burns to both legs and had undergone nine operations. Bones on his legs were exposed.
Mr Hicks was admitted to intensive care and spent three weeks in St James’ Hospital following the “very vicious assault” in which he was punched and kicked unconscious.
Today Judge Martin Nolan sentenced O’Mahoney to five years for producing a knife during the incident with his mother and threatening gardaí with a broken bottle in a second incident.
O’Mahoney of Swan Grove, Ranelagh pleaded guilty at Dublin Circuit Criminal Court to production of a knife at Oakcourt Lawns, Palmerstown, on September 26, 2010 and production of a glass bottle on February 2, 2011.
He was on bail for the first offence when he committed the second. He has 20 previous convictions including the three attacks.
“It seems to me I have a duty to protect society from him. He has a history of incredibly sadistic and violent behaviour,” Judge Nolan commented.
He suspended the final 18 months of the consecutive term having taken into account that O’Mahoney pleaded guilty to the offence and has recently been diagnosed with schizophrenia.
Judge Nolan noted that psychiatric reports before the court concluded that O’Mahoney’s mental illness “was not the driving force behind his criminality” and an alcohol dependant syndrome was the cause of his offending behaviour.
“His excessive drinking brings out character traits that make him violent,” Judge Nolan said before he directed that O’Mahoney be of good behaviour for two years upon his release from prison and remain under the supervision of the Probation Service for that time.
Both gardaí in the case agreed with Seoirse Ó Dúnlaing BL, defending, that O’Mahoney was intoxicated at the time of his arrest and has since been diagnosed with schizophrenia.
O’Mahoney’s mother Sharon told the court that although she had taken her son to many doctors seeking medical advice, he was not diagnosed until his remand in the Central Mental Hospital.
She said she had given up her job to become his full-time carer and will continue to support him upon his release from prison.
Mr Ó Dúnlaing asked Judge Nolan to accept that since his client’s remand in custody, he has been making efforts to get help and is making progress. He said he is taking his medication and his urine tests have been clear of illicit substances.
