The details of just how widespread contamination was in DNA testing for the Claremont Serial Killer case was detailed on day 54.

At least seven exhibits were found to have been contaminated, six with the DNA of the very scientists analysing them, and one with the DNA of a victim of a completely unrelated crime.

The details of how the contamination occurred were laid out by PathWest scientist Scott Egan, who himself is one of the contributors of the contamination.

It’s, as Tim Clarke says in this episode, an embarrassing day for the prosecution.

Joined by criminal defence lawyer Damien Cripps, Natalie and Tim discuss what this bombshell evidence means for the prosecution’s case, and what they would have to do next to gain back legal ground.

The question remains however, so what? These exhibits aren’t the crucial samples the the prosecution say contained Bradley Edwards’ DNA, why is this important?

The podcast team discuss this question, and answer some of your listener questions too.
