Blood found at the crime scene is the only piece of evidence yet to be investigated in the Year 6 CSI Science project.
Teachers use secondary science equipment to enable the children to undertake their own DNA testing. Will the resulting DNA fingerprints help solve the school burglary?
Included in the programme is an interview with Professor Sir Alec Jefferys, the man who discovered DNA fingerprinting in 1984. He discusses the social impact of his discovery, and how it has changed forensic police work forever.
