In July, the court heard that the family computer was used to search for ``gay anal sex in Taiwan'' Web sites in April, 2003 - a time when Robert Kissel was the only member of the family in Hong Kong, and a few days before he took a trip to Taiwan.

Benedict Pasco, the computer expert for Nancy Kissel's defense team, submitted a report and testified as to how he used Netanalysis and EnCase software to search the hard drives of the computers and recreate the Web sites that had been visited.

Pasco distinguished between the terms which were typed in himself in order to search the hard drive of the computer, and the words typed by the users of the computer using the Google search engine.

On April 4, 2003, it was the user of the computer who typed in ``MPEG sex'' and ``wife is a bitch'' into the Google search engine.

In some instances, the user seems to have gone through several pages of results offered by Google, said Pasco.

But he added there were terms such as ``Gay Ultra'' printed in his report, which showed what he himself was looking for in the hard drive of the computer, not what the user had searched for on the Internet.

Nancy Kissel, 41, is accused of serving her husband a pink milkshake laced with sedatives which left him unconscious at the foot of the bed as she bludgeoned him to death with a heavy metal ornament on November 2, 2003, in their luxury Parkview apartment.

She has testified there was a furious fight that night in which she feared for her life as her husband bore down on her swinging a baseball bat, repeatedly saying: ``I'm going to kill you, you bitch.'' She has accepted that she killed her husband, but claims she cannot recall how she came to inflict five fatal wounds to the side of his head.

She denies the charge of murder and is out on bail.

The decomposing body of Robert Kissel, a high-flying Merrill Lynch banker, was found wrapped in a rug and locked in a storeroom in the Parkview residential complex in the early hours of November 7.

The accused has testified that her husband routinely sodomized her and that, given the suggestion he surfed the Internet for homosexual porn sites, it now made sense to her that ``he had a fascination'' for anal sex.

She also said her children once drew her attention to pornographic images which had popped up while they were using the family computer.

Friday, her defense counsel, Alexander King SC, asked Pasco whether pop-up images would return on a computer that had been used to visit certain Internet sites.

Pasco replied that in 2002 and 2003, spam and anti-virus software ``were not as sophisticated as present'' - meaning that Web sites, once visited, would be able to scan a computer.

During cross-examination by Senior Assistant Director of Public Prosecutions Peter Chapman, Pasco said that he was instructed by the defense solicitors primarily to look for homosexual material.

Chapman suggested that Pasco's report on Internet activity of those computers was ``incomplete.''

Pasco said some of the Internet history files were originally deleted and that it was not possible to recover the date those Web sites were visited.

The defense said it should complete submitting its evidence next week.

The trial continues Monday before Justice Michael Lunn.
