Forensic Science

Today, two  detectives came in to talk about Forensic Science. Gavin Cross worked in fingerprints and footprints. They talked about how they analyze a crime scene and how they figure out who the culprit was. They took us through step by step via a picture slideshow.  One really cool thing that we learnt about was Luminol. This is a substance that they spray on the floor to detect any blood traces that we can;t see. They then put UV light over it. It was really informative and I learnt loads of new things!
