Summary of Follow-up Soil Evidence Analysis
Follow-up investigation of the soil components yielded several pieces of information. The soil samples taken from the crime scene were comprised of two distinct layers. The layer furthest away from the shoe sole (the newest layer) yielded no discriminating characteristics. However, layer closest to the sole (oldest layer) contained several components which were analyzed by several scientists.
Pollen
Dr. Melvin McCoy, a palynologist at the Univeristy of Mississippi, found three distinct types of pollen found in the oldest soil sample:

Feathers & Animal Hairs
Dr. John Trott, an ornithologist at the University of Mississippi in Oxford, identified the feathers as belonging to Anhinga anhinga or "snakebird," which is commonly found near freshwater ponds and swamps in the south, especially in areas containing cypress trees. Dr. Linda Wayne, a microscopist in the biology department at the University of Southern Mississippi, identified three major animal hairs present in the soil samples:

Conclusion:
Dr. Avril Warner, a wetlands ecologist at Tulane University, reviewed the above findings and concluded that the oldest soil sample likely originated in a swampy, wetland area in the south, possibly southern Alabama, Louisiana, or Mississippi. Dr. Warner further noted that all three animals are common game for hunters.
