Blood and DNA Evidence: Crime-Solving Science Experiments (Forensic Science Projects)

The police are investigating the 1983 murder of Charlotte Stewart. A blood-soaked cloth is found, but they have no leads and no suspects. Soon the case turns colds. Ten years later, DNA evidence links Richard Jackson to the crime; he is arrested and sentenced to life imprisonment. The real-life crime stories in this book are followed by science experiments and project ideas that highlight the forensic technique used to solve the crime. How do you know if a stain is really blood? How can the shape of a blood splatter tell an investigator what happened during the crime? How does DNA evidence rule out suspects? Take careful notes in your case notebook; your observations could crack the case!
