That crucial Telstra Blue fibre was again under the spotlight on day 70 of the Claremont Serial Killings trial, this time by the defence.

Joined by prominent Perth criminal defence lawyer Tom Percy QC, the podcast team discuss what the defence will try to argue to place enough reasonable doubt in the fibre evidence.

The argument - that the ‘Telstra Blue’ colour wasn’t always exclusive to Telstra, the colour was supplied to other, smaller businesses throughout the 90s.

But the prosecution say that it’s the combination of the fibre material - the unique mixture of cotton and viscose - and the Telstra blue colour that makes it exclusive to Telstra workers’ uniforms.

Hear the opinion of one fo Perth’s top criminal defence lawyers about how he thinks the trial is going, and whether he thinks - if convicted - the location of Sarah Spiers could be revealed.

Join Natalie Bonjolo, Tim Clarke and Tom Percy QC as they discuss day 70 of WA's trial of the century.

The trial will take a break over Easter, returning on Tuesday April 14.
