A crime scene has been discovered by Year 6 pupils at Wylde Green Primary School in the West Midlands.
Scenes of Crime Officer Robin Slater invites the children to become crime scene investigators, gathering and examining evidence from the scene.
The pupils interview and take fingerprints from suspects, use microscopes to examine fibres and assess chromatography in an attempt to unravel the mystery.
The evidence links all five suspects to the crime, but only DNA fingerprinting will reveal the real culprit.
