THE search for Corryn Rayney’s killer has come up empty, despite an exhaustive year-long investigation.

On Thursday Police Commissioner Karl O’Callaghan detailed the lengths ‘Operation Delve’ went to in order to find a resolution in the case of Ms Rayney, whose body was found in Kings Park in August 2007.

Her husband, barrister Lloyd Rayney, was acquitted of her murder in 2012.

Mr O’Callaghan said he was confident Operation Delve had “undertaken all actions which are currently available to police”.

“All identified lines of inquiry have been rigorously pursued and exhausted,” he said.

During the investigation, which involved detectives from interstate and UK firm Cellmark Forensic Services to analyse DNA, police investigated 92 people over Ms Rayney’s death.

They examined six primary and 61 secondary forensic scenes, thousands of electronic files, some 4000 exhibits and obtained DNA and/or fingerprints from an additional 300 people.

“At this point there is currently insufficient evidence to charge any person with an offence in relation to Corryn Rayney’s murder. The matter remains an unsolved homicide,” Mr O’Callaghan said,

“As such it will be transferred to the Special Crimes Squad from where any new leads or avenues of inquiry that emerge will be further actioned.

“It’s an unfortunate reality of many cold case inquiries that the passage of time has taken its toll.

“In this case some aspects of the original murder investigation could not be revisited, recovered or resolved by the new team.”

A report has been prepared for the Coroner, who will conduct an assessment before deciding whether to launch a coronial inquiry.
