How do forensic investigators decipher the scene of a violent car crash? Why is the filament in a brake light so important? And what evidence can lead investigators down the wrong path? Dr Raphael Grzebieta is an expert in car crash analysis, and has worked for decades in the field. His goal is to bring road safety to the fore of transport conversations, and refuses to acknowledge car crashes as accidents, claiming there is always a reason.  Join host Kathryn Fox as she unpacks the work of Raphael, and uncovers just how he and other investigators come to their forensic conclusions.  If this content raised issues for you, the number for Life Line is 13 11 14.
