Identification on the Cause of Skin Damage through the Application of 1,2-Indanedione reagent as Developing Agent of Latent Fingerprints

초록

This is the case of assault lethality that the suspect obstinately denied committing fatal violence. The wound was defined as an extension injury according to the size and the from of unusual laceration and the shape of wound margin on the 56-year-old female victim’s knee. As a report of The National Forensic Service (NFS) for testing the clothing in order to find the mechanism of the wound, there was no unusual impact mark found around the stretch laceration on the knee, but was an impact mark, which is similar to a shoe shape, reacting to 1,2-indanedione at the thigh near the stretch laceration. As a result, considering the feature of the clothing with a little elasticity, it was estimated that the kneeling position could make the clothing tightly stuck to the skin and pulled, and this could cause the extension injury by the extension force caused on the skin. This would be a ideal case that 1,2-indanedione used in the development of the latent fingerprint was applied to analysis of the body injury, traces of the clothing and then crime scene reconstruction.
