  1. Forensic Palynology Study of pollen, spores, and other microscopic plant parts

  2. Pollen and Spores Natures Fingerprints of Plants

  3. Dinoflagellate Algae Fungal spores

  4. Pollen Background • Pollen is the male cell of flowering/cone bearing plants • Microscopic • Found on nearly everything (unknowingly )—Locard’s Principle • Comes in a vast array of shapes, sizes, aperture openings, & surface textures

  5. Pollen Background • Usually pollen types of different species within a single genus look similar Different species of daisies

  6. Pollen Diversity Willow Tree Hay Fever Pollen Forget-Me-Not Pine Tree Persian Silk Tree

  7. Kansas Prairie Pollen Prints • Each location produces a unique “pollen print” that is often so specific that it can be used to identify that precise location Texas Louisiana Georgia

  8. Uses in forensics… • Identify the pollen/minerals and determine where they came from and when they occur • Determine if a body was in a particular place at a certain time • Season in which crime was committed

  9. Pollen Tells a Story • For instance, a dead body may be found in the woods, and the clothes may contain pollen that are found in a place other than where the body was found. That indicates that the body was moved.

  10. How to Analyze Pollen • Using a microscope • Look for characteristics such as shape, size, surface texture, & aperture • Compare specimens (from crime scene to suspect, from victim to suspect etc.)

  11. Provides a piece to the Puzzle • Will probably not be the sole piece of evidence used to convict a person of a crime • Simply provides a “link”
