Forensic Palynology

Study of pollen, spores, and other microscopic plant parts

pollen and spores
Pollen and Spores

Natures Fingerprints of Plants

pollen background
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

Pollen Background
  • Usually pollen types of different species within a single genus look similar

Different species of daisies

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

uses in forensics
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
pollen tells a story
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.
how to analyze pollen
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.)
provides a piece to the puzzle
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”
