Toolmark Examination in Criminalistics

The video tutorial, presented by Lady Patricia Jiko Ubba, covers the role of tool marks in criminal investigations. It explains how forensic scientists use tool marks to identify tools used at crime scenes and link them to suspects. The tutorial details different types of tool marks, including compression, sliding, and cutting marks, and emphasizes the importance of tool mark examination in establishing connections between suspects and crime scenes. It also provides guidelines for collecting tool mark evidence without damaging it, highlighting the need for careful handling to preserve trace evidence.
