That life form can be anything: bacteria, pollen, diatoms, a birch seed or a cat’s hair. They are all green, silent witnesses. Forensic investigator Irene Kuiper shows that even a teaspoon of soil can make the difference between a conviction or acquittal. German entomologist (insect expert) Mark Benecke examines insects found at a crime scene.
The animals that Benecke finds tell him how long a corpse has been lying somewhere and whether the body has been moved. Next to the Amsterdam UMC is a field where bodies are buried for science. Forensic biophysicist Maurice Aalders is investigating how vegetation can reveal the location of a grave.
