Final answer:
Three new types of evidence used in determining who committed crimes that were not available at the time of Poe's story include forensic anthropology, chemical analysis, and fingerprint analysis.
Step-by-step explanation:
Three new types of evidence used in determining who committed crimes that were not available at the time of Poe's story include:
- Forensic anthropology: This field uses the analysis of human remains to reconstruct crime scenes and determine cause of death. For example, examining cut marks on a skull can provide evidence of intentional chopping with a sharp blade, as seen in the case of the Jamestown colony.
- Chemical analysis: Chemists can collect evidence from crime scenes by analyzing substances such as blood, hair, or soil. The properties observed through chemical analysis can provide valuable clues about the crime and help identify the perpetrator.
- Fingerprint analysis: Advances in technology have made it possible to analyze fingerprints in more detail and with better accuracy. By comparing fingerprints found at a crime scene with a database of known fingerprints, investigators can determine if a suspect was present at the scene.
