Man accused of stabbings 'had amnesia'

An orthopaedic consultant has revealed a psychiatric nurse accused of stabbing six people experienced amnesia and problems forming words after the alleged incident.

Kieran O'Shea, giving defence evidence based on medical notes, said Brian Quinn (46) showed "signs of acute confusion" while being treated at St James's Hospital for possible head injuries after a baseball bat beating.

Quinn's amnesia and dysarthria, a motor speech disorder, resolved over time.

The accused, previously of Deer Park Avenue, Kiltipper in Tallaght, now living in Balbriggan, has pleaded not guilty at Dublin Circuit Criminal Court to intentionally or recklessly causing serious harm to James Toner Snr, Stephen Keogh and Lee Harte on October 9, 2011 at Deer Park Avenue.

He pleaded not guilty to assault causing harm to Kurtis Lennon, James Toner Jnr and Robert Ryan, and pleaded not guilty to production of a knife.


Mr O'Shea told Giollaiosa O'Lideadha SC, defending, that Quinn had bruises and bumps on his head but no loss of consciousness or skull fractures.

He agreed with Paul Carroll BL, prosecuting, that "presumably" the accused had some recollection of events after the 20-minute period of amnesia.

Quinn told gardai during interview he grabbed a "pen or corkscrew" from his pocket and fought his way out of his house to come to his partner's aid during the alleged incident.

Garda Adrian O'Sullivan said the accused described how he'd tried to pull his partner away after Mr Toner Snr allegedly punched her outside the home while she smoked a cigarette.

Quinn said he was struck on the head with a baseball bat and pulled through his hallway by about eight or nine people. He said he then saw two kicking and standing on his partner.

Gda O'Sullivan said the accused said he was "not sure what happened next" after he grabbed the "pen or corkscrew".

He said the accused claimed he chased the young men down the road when he saw one trying to grab his partner again.

The trial continues before Judge Carmel Stewart and a jury of nine men and three women.
