This workshop will introduce participants to the concept of trace evidence. Wherever they step, whatever they touch, whatever they leave, even unconsciously, will serve as a silent witness against them. We will guide you through a mock murder scene (with full PPE if required) describing the evidence that is critical to aid in the investigation through forensic science including Blood spatter, hairs and fibres, fingerprints and footwear and how we can utilise many differing chemicals to develop and preserve the items. Hands on workstations will allow you to develop and preserve fingerprints and footwear. We can show how this can be replicated for your students within the classroom.
