TEACHING THE SPECIFICS TO STUDY TRACES OF HANDS, SMELL AND DNA TRACES OF A PERSON ON FIREARMS TO CADETS OF EDUCATIONAL INSTITUTIONS OF THE MINISTRY OF INTERNAL AFFAIRS

Abstract

The article deals with the order and features of the study of traces of hands, smell and DNA traces of a person on a firearm. The authors come to the conclusion that in a comprehensive study of firearms, it is necessary to collect human odor traces as they remain on the metal surfaces of firearms for a short time. Besides, at detection on a surface of firearms of traces of hands suitable for identification of the person, preference is given to withdrawal of these traces as washing off (scraping) from a surface of object of traces of a sweat-relating substance does not guarantee a chance to identify DNA in it. The authors conclude that in the forensic classes to cadets it is important to convey the idea that the detection of traces of hands, smell and DNA traces of a person should be carried out strictly in accordance with the available methodical recommendations of the Expert-Criminal Center of the Russian Interior Ministry. This will improve the use of firearms and the identification of those involved in the commission of the crimes.
