Questions over murder details leak

WA Police conducted internal investigations to try and ascertain how members of the media were learning details of the police investigation into Corryn Rayney's death, Lloyd Rayney's Supreme Court murder trial has been told.

Appearing as a witness today, Senior Sergeant Jack Lee was asked questions about the search of the Rayneys' Como home on September 20, 2007, at which a significant media contingent was present.

Asked under cross-examination if he had leaked details of the search to the media, Sen. Sgt Lee said no.

He said the media was present at a number of searches conducted by police, adding that he had "no idea" how that came about.

"We ran a number of internal investigations trying to determine who was talking to the media," Sen. Sgt Lee said.

Sen. Sgt Lee was the officer who controversially labelled Mr Rayney as the "prime" and "only" suspect in his wife's murder.

Sen. Sgt Lee's comments were made on the same day as the search of the Rayneys' home.

Mr Rayney's lawyer, David Edwardson, asked Sen. Sgt Lee about a conversation he allegedly had with Mr Rayney on the day of the search in relation to the media's presence.

"I'm suggesting to you that you told Mr Rayney, 'We are disappointed the police gave this information to the media'," Mr Edwardson said.

Mr Edwardson said Mr Rayney replied with words to the effect of "you're disappointed, I'm f…ing furious".

Sen. Sgt Lee denied the conversation took place.

Mr Edwardson also suggested Mr Rayney complained to Sen. Sgt Lee that he was learning key facts about the police investigation through the media instead of being kept up to date by police.
