On Day 64 of the Claremont Serial Killings trial, two forensic police officers detailed how they painstakingly sifted through Jane Rimmer’s hair mass 13 years after her post-mortem.

It was a sensitive operation for two reasons.

After being in frozen storage for more than a decade, Jane’s hair mass was extremely brittle, and still had icicles on it.

But these officers were very aware they were sifting through the hair of a murdered woman.

As forensic expert Brendan Chapman explains in this epsidode, while collecting and retaining a hair mass during a post-mortem is common, actually testing a hair mass isn’t - because mostly, it’s taken as a, what he called the “one per center” a “last resort” exhibit to examine.

Through his experience, cases tend to get solved before sifting through a hair mass is needed.

But this was a “one per center” case, and the prosecution would say that one per cent chance of testing paid off.

The prosecution say 22 fibres, 20 of which the prosecution say matched a white commodore station wagon Bradley Edwards had access to at the time, and 2 which they say match specially-made Telstra pants worn by the accused in the 90s were found in Jane Rimmer’s hair.
