Forensic Use of Gel Lifters

In this video, Mike McCutcheon demonstrates the use of black gel lifters in forensic investigations. He explains how to lift fingerprints and foot impressions from various surfaces, both with and without the use of fingerprint powder. The video covers the versatility of gel lifters, including their ability to be cut to size and their effectiveness on textured surfaces. McCutcheon also discusses the importance of proper lighting techniques and provides tips for transporting and storing lifted impressions. The video concludes with a demonstration of using gel lifters for indented writing analysis.
