Identification of methods for evidence collection bite site of the victims' bodies

The biggest problem in evidence collection of crime scenes is not only the quality and quantity of the available equipment, but also the lack of training, not using new techniques and methods of evidence collection due to the importance and effective role of material reasons in the crime scene. It is offered for those who deal with crime scene investigation and gathering evidence and reasons in some way, to gain the necessary training and experience in this field, so the purpose of this study is to scientific promote the crime scene investigation experts and laboratories by studying libraries to identify evidence collection methods were determined from the bite site of the victims. The effects of biting are among the unique material reasons resulting from the surface pressure on the other surface, which are observed in two-dimensional and three-dimensional designs and by using powder spraying methods as well as molding, which is unique to three-dimensional designs of biting effects. Among the proposed methods, which itself has a high technical diversity, is the method of shooting with a camera and special filters that cause the least damage to the work itself and allow experts to evidence collection several times. Photography using ultraviolet light, which accurately shows details, and infrared light, which can illuminate the basic features of works, can provide accurate and usable works for experts to document.
