Summary

In this episode, we explore botanical forensics through the compelling concept of the “Guilty Tree,” where plant growth rings and microscopic pollen grains serve as silent witnesses in long-cold criminal cases. Dendrochronology and palynology allow investigators to pinpoint burial sites and timelines with remarkable precision, even decades after a crime. The discussion highlights how these natural records provide objective, tamper-resistant evidence that has solved cases where traditional forensic methods failed.
