Former forensic police officer Robert Hemelaar gave his evidence for the whole of day 21 of the Claremont Serial Killings Trial.

He narrated an hour-long video from Ciara Glennon’s burial site, revealing graphic details and forensic clues as to how police collected and stored DNA samples found on the 27-year-old’s body.

Joined in the studio by forensic expert Brendan Chapman, Natalie Bonjolo, Tim Clarke and Emily Moulton take you through exactly how forensic officers collect samples, and most importantly, how they avoid contamination.

A key piece of evidence was also hinted at during the trial - the fact that some of Ciara Glennon’s fingernails were broken, coupled with the defensive wounds on her arms, the prosecution said that Ciara fought for her life the night she died.

But under those broken fingernails, the prosecution says was Bradley Edwards’ DNA.
