An examination experiment has been carried out to investigate whether fingerprint powder and lifting technique can recover and transfer latent fingerprints from human skin surfaces of dead bodies. For recovery Swedish Black powder and for transfer White Fingerprint Gelatine were used.
Donors placed fingerprints on the human skin surfaces. Finger marks were then in all cases recovered with Swedish Black powder. The procedure was repeated after 2, 3, 4 and 5 hours. Treated finger marks were secured and preserved as latent fingerprint evidence by lifting process. We recovered 8% finger marks suitable for further examination of all deposited samples on the human skin surfaces.
Crime scene investigation is a process that aims at recording the scene as it is first encountered, and recognizing and collecting all physical evidence potentially relevant to the solution of the case. Crime scene investigators who have received comprehensive forensic training usually quickly take over the work at the scene and implement ideas from research institutes in practice. The personnel processing crime scenes should be aware of equipment necessary to process a crime scene and a mechanism to secure and transport the evidence to the laboratory. Physical evidence has the potential to play a critical role in the overall investigation and resolution of a suspected criminal act. We can therefore say that in investigating crimes, we are using traditional investigative approaches with modern methods and "state of the art" tools.
