Summary
This study introduces a semi-automatic system for footwear impression comparison, aiding criminal investigations. The system efficiently links crime scenes by matching shoeprints in a database.
Area of Science:
- Forensic Science
- Computer Science
- Criminal Justice
Background:
- Footwear impressions are crucial evidence in criminal investigations, linking suspects to scenes.
- They also provide forensic intelligence, connecting crime scenes when suspects are unknown.
Purpose of the Study:
- To develop a computer database and semi-automatic system for footwear impression comparison.
- To enhance the efficiency and effectiveness of forensic intelligence gathering.
Main Methods:
- A structured manual coding system for footwear impression elements by Crime Scene Investigators (CSIs).
- A computer algorithm for comparing query impressions against the database based on pattern similarity and geographic proximity.
Main Results:
- A database of 284 real crime scene footwear impressions was utilized.
- The system achieved a 30% match rate for the same shoe model.
- Matches were frequently found within the top five results.
Conclusions:
- The semi-automatic footwear comparison system is simple, cost-effective, and efficient.
- It demonstrates significant potential for linking disparate crime scenes through footwear evidence.
