Fingerprints and footwear impressions are critical pieces of evidence in crime scene investigations. While criminals often wear masks and gloves, they rarely modify their footwear, making it a valuable source of evidence. Properly collected footwear impressions can provide detailed information about suspects and their movements.
Traditional methods like forensic photography and casting have limitations and can be destructive. 3D scanning offers a non-destructive, accurate, and efficient alternative. This technology captures detailed 3D models of footwear impressions, preserving evidence without damage and enabling easy sharing among investigators. Recent studies, including one by Ontario Tech University, have demonstrated the effectiveness of 3D scanning in forensic investigations, showing it as a viable replacement for traditional methods.
