S2E35: A Lesson in DNA

The forensic scientist who tested the evidence which is crucial to the prosecution’s case today took the stand. Anna-Marie Ashley from Path West, detailed in painfully intricate detail of how she extracted the DNA from the Karrakatta rape victim’s intimate swabs, which revealed DNA which we now know is Bradley Edwards’ - for the first time. She also tested Ciara Glennon’s fingernail samples - the crucial piece of evidence which the prosecution say links the Karrakatta rape, which Bradley Edwards has pleaded guilty to, with the murder of Ciara Glennon. It was an extremely scientific, and detail driven day in court, luckily, forensic DNA expert Brendan Chapman joined Natalie and Tim in the studio to help us try to understand the process of DNA extraction. Brendan’s informative introduction into DNA is a must-listen for those of us following the trial, because we’ve been warned - it’s only going to get more complicated, especially when the defence take their turn cross examining the evidence.
