Lawyers for two of the three men charged in connection with the seizure of €440m worth of cocaine in west Cork last year have asked the jury to find them not guilty because of a lack of evidence.
Counsel for 45-year-old Martin Wanden said gardaí believed he was guilty because he was rescued from the water at Dunlough Bay among the bales of cocaine.
A lawyer for 48-year-old Perry Wharrie told the jury that if they do their job properly, they will acquit him.
Mr Wharrie, 48, from Essex in England, is the only one of the three defendants who has not taken the witness stand in this trial.
This afternoon his counsel, Tim O'Leary, told the jury he had taken that decision because of the lack of evidence against his client.
The trial was told that Mr Wharrie went to Dunlough Bay with him on the morning of 2 July last year after Mr Daly was told his brother Michael was in difficulty in the water there.
However, they left the scene when they saw that the man in trouble was floating among bales of drugs. They were arrested two days later.
In his closing submission today, Mr O'Leary asked the jury to put aside what he described as the 'high production values' of this trial: the scale of the drugs haul and the large cast of characters.
He said the case against Mr Wharrie is very difficult, very subtle and very remote.
Senior Counsel for Mr Wanden, Padraig Dwyer, said the gardaí became fixated with his client. He said because of the position Mr Wanden was found in at Dunlough Bay, they had a vision that he could only be guilty and it was just a matter of getting the evidence against him.
He insisted, however, that there was only conjecture and speculation to suggest that Mr Wanden was involved with these drugs.
Judge Sean O'Donnabhain will charge the jury on the law and how to apply it tomorrow and Friday and the jury of nine men and two women will begin their deliberations on Monday.
