Perth barrister Lloyd Rayney is calling for new investigation into his wife’s murder, claiming a different police team is needed to find his wife’s real killer.

The father-of-two once named as the “prime and only” suspect in the investigation into Corryn Rayney’s murder ­– and who was later acquitted of the crime in the WA Supreme Court – told Channel 9’s 60 Minutes he was “fighting for the truth” and questioned WA Police’s handing of evidence and leads in the case.

The show also aired claims a seed pod found in Mrs Rayney’s body bag had been planted by police.

Mrs Rayney went missing after a boot-scooting class in Bentley on August 7, 2007, her body later discovered buried in King’s Park.
