One of the four men on trial for their part in the fatal shooting of a Limerick nightclub doorman told gardaí he had never seen a gun in his life.
Det Garda Darragh O'Sullivan told Denis Vaughan Buckley SC, prosecuting, that accused man Gary Campion told him the chief prosecution witness had "killed four or five people in England. He came over to Ireland and was doing hits."
Mr Campion told gardaí that James Martin Cahill, who is serving a life sentence for shooting dead Brian Fitzgerald in November 2002, was a mad man.
"He's a serial killer. He should be signed away. He's involved in about five killings."
Det Garda O'Sullivan said Mr Campion denied any involvement in the murder and said he owned a slightly different bike to the one found burned out in a laneway beside a garage on the night of the murder.
Mr Campion (24), Pineview Gardens, Moyross, Limerick; John (27) and Desmond (23) Dundon, both Ballinacurra Weston, Co Limerick; and Anthony Kelly (50), with an address at Kilrush, Co Clare, all plead not guilty to murdering Mr Fitzgerald in the early hours of November 29th, 2002, at Brookhaven Walk, Mill Road, Corbally, Limerick.
Det Garda Éamon O'Neill told Mr Buckley that Mr Kelly said he had been meeting his accountant on November 28th in Limerick but had cancelled after forgetting some papers.
Mr Kelly had said he returned home to Clare and went to bed early. He had a gym in his house and worked out at about 7pm and was in bed by 9.30 or 10pm.
He said he did not leave again until he went to his furniture shop the following morning to receive a delivery.
The trial continues at the Central Criminal Court sitting at Cloverhill today when the prosecution case is expected to conclude.
