A witness in a murder trial told the court yesterday the accused was a "psycho" and had murdered the dead man.
Mr Christopher Curry, Bally ogan Drive, Leopardstown, Co Dublin, told the Central Criminal Court Mr Joseph Delaney murdered Mr Mark Dwyer (23) in 1996.
"Joe murdered Mark and at the end of the day will have to answer to somebody for it," he said.
Mr Delaney (54), formerly of La Rochelle, Naas, Co Kildare, has pleaded not guilty to the murder of Mr Dwyer on or about December 14th, 1996.
Mr Delaney also pleaded not guilty to falsely imprisoning Mr Dwyer and detaining him against his will at Foster Terrace, Ballybough, Dublin, on the same date.
Mr Delaney allegedly had drugs with an estimated street value of between £300,000 and £400,000 stolen from him during a prearranged drop at a pub in Dublin and he suspected the deceased of taking the drugs.
Mr Curry told gardai in a statement: "I want to see Joe hung. He's a psycho and I'm prepared to wear a [surveillance] wire.
"He did kill Mark. It was a case of Joe still at large, that was it," he said. "I know him. They don't know him. I know Joe longer than you do," he told defence counsel Mr Blaise O'Carroll SC.
Describing Mr Curry's evidence as "saturated with prejudice of anyone who would set anyone up", Mr O'Carroll put it to Mr Curry that "the gist of it is that this is another piece of fabrication".
Mr Curry responded by saying "Joe was about the way you are. He analysed everything to the point where everyone was a suspect.
"Every week he had a different plan, a different theory" about who was responsible for stealing 30-40,000 ecstasy tablets from him during the prearranged drop at a Dublin pub.
The jury was told the accused's son, Scott Delaney, is serving a life sentence for Mr Dwyer's murder and will be giving prosecution evidence against his father.
Prosecution counsel previously said the State pathologist would give evidence that Mr Dwyer died from a laceration of the brain due to a single gunshot wound to the back of the head, fired at "virtual contact range".
The case before Mr Justice Quirke and a jury continues today.
