Planted at the Scene of the Crime: The Science of Forensic Botany

This talk will examine the use of plants and other organisms such as algae and fungi traditionally grouped with plants as evidence in criminal investigations. Starting with the wood grain of the ladder left at the Lindbergh residence and continuing into modern genetic techniques, we will review how plant evidence has in the past and can be expected in the future to help  solve crimes, prosecute the guilty, and free the innocent.
