The Central Criminal Court has heard that a computer and other electronic devices were seized by gardaí during a search of Patrick Quirke's home in May 2013.
Detective Sergeant John Keane was giving evidence in the trial of Mr Quirke of Breanshamore, Co Tipperary, who is accused of murdering Bobby Ryan, a part-time DJ known as Mr Moonlight.
Mr Quirke has pleaded not guilty to the murder of Mr Ryan at an unknown location on a date between 3 June 2011 and 30 April 2013.
Det Sgt Keane said he and other members of an investigation team called to Mr Quirke's home on 17 May 2013 and searched the home and farm of Mr Quirke for a number of hours.
They also searched an adjoining farm which was being rented.
This was done with Mr Quirke's permission.
He said before beginning the search he cautioned Mr Quirke and gave him the warrant to read, who asked him what they were looking for.
He gave him the warrant to read and Mr Quirke said the media were wrong when they said clothes and a wallet were found in the tank with Mr Ryan's body.
During cross-examination the witness confirmed that Mr Quirke made this comment after reading the warrant which listed the items being searched for as Mr Ryan's clothing, footwear, jewellery, keys and a weapon.
Det Sgt Keane said a computer and other electronic devices along with documents, a pair of overalls and a portfolio were shown to Mr Quirke before they were taken away.
He said the search began at around 9.45 and they left at 16.45.
Earlier, a farmer and agricultural contractor told the court he never used a run-off tank where Mr Ryan's body was found to draw water for spreading slurry.
Patrick O'Donnell said he was often engaged by Mr Quirke to empty slurry tanks and spread it on fields at his home farm and the farm he was leasing at Fawnagowan.
He said he never used the run-off tank to draw water needed to dilute slurry before spreading it.
He said the tank would not contain the volume of water needed as such tanks, which were built in the 1970s, were porous.
He said he would be engaged in much larger jobs and would need to draw water from a larger source such as a river.
He also said farmers spread smaller amounts of slurry themselves throughout the year and would not need his services for smaller jobs.
He said Mr Quirke had asked him in March 2013 if he could borrow his tractor and agitator as he was having a problem with the slurry on the farm at Fawnagowan.
