Peter Quinn (52) hit a man over a dozen times in the head with a metal chair while he was on the ground.
He also kicked the victim two or three times in the head and hit him in the abdomen with the man’s own crutch.
Quinn, of no fixed abode, pleaded guilty at Dublin Circuit Criminal Court to assault causing harm and production of an article during a dispute at Carmen's Hall hostel, Francis Street, Dublin City centre, on January 30, 2020.
He has 106 previous convictions, including convictions for assault, robbery, and burglary.
Passing sentence, Judge Melanie Greally said that although the victim had initially approached in a hostile way, Quinn had responded by assaulting him in an “extremely brutal and violent manner”.
“He used a chair to strike the victim repeatedly over the head and upper body, continuing while the victim lay utterly defenceless and barely conscious on the floor,” she said.
The court heard Quinn had spent time in numerous State institutions from the age of five and had suffered significant abuse.
Judge Greally said the injured man had not submitted a Victim Impact Statement, but medical reports showed he had received 25 stitches to his head and five to his eyes, as well as severe bruising to the upper body. The injured party also reported suffering flashbacks to the attack.
She noted a psychiatric report showing that Quinn suffers from schizophrenia exacerbated by substance abuse issues.
She acknowledged that Quinn had had a very difficult early life and had been in and out of care settings and health facilities as a child. She also noted a positive probation report showing Quinn was engaging with support services.
Garda Conor Kelly told Shaun Smyth BL, prosecuting, that both the accused and the victims were guests of Carmen’s Hall Hostel when an argument sprang up between them.
The court heard Quinn got a butter knife from the kitchen and went towards the victim before retreating to the women’s corridor.
CCTV footage was shown to the court showing the injured man appearing to wield his single crutch at the accused man, who grabbed a fire extinguisher and threw it at the victim causing it to go off.
Quinn then proceeded to beat the injured party over the head with a folded-up metal chair and then kick him several times to the head.
He also used the victim’s crutch to beat him in the abdomen.
Gda Kelly agreed with counsel for the defence that Quinn was in a deluded state at the time of the attack and had been diagnosed with multiple and very serious psychological disorders.
Judge Greally deferred sentencing on the second charge of production of an article to June 24.
