Inspector Drake inspected a hijacked delivery truck abandoned in a desert. The driver claimed he was ambushed by bandits who forced him out at gunpoint and drove off with the vehicle. Drake noticed the driver's heavy boots were completely caked in thick, wet river clay, while the desert sand for miles around was dry and powdery. Drake arrested the driver. Why?
The driver's boots had river clay, not desert sand
If the driver had been walking around in the dry desert after being forced out of the truck, his boots would be covered in dry sand, not wet river clay. The clay proved he had recently been near a riverbank, disproving his desert ambush story.
