Guilty plea in Perth body-in-boot murder

One of five people charged with the murder of a man whose body was found in the boot of a burnt-out car has pleaded guilty at the start of a lengthy trial in Perth.

The remains of Travis Bennjamin Mills, 30, were found on Good Friday last year in Hilbert.

Justine Claire Campbell entered the guilty plea in the Supreme Court of Western Australia before the 45-day trial gets under way.

The other accused are her husband Darren Greame Kenneth Campbell, Darryl Raymond Newton, Seleena Monique Ruthsalz and her mother Joanne Christine Ruthsalz.

The trial is due to start on Monday.
