THE CONNECTION BETWEEN THE TYPES OF PAPILLARY PATTERNS OF FINGERS AND TOES IN THE ASPECT OF THE POSSIBILITY OF ESTABLISHING THE BELONGING OF LIMBS TO ONE CORPSE IN THE FORENSIC EXAMINATION OF FRAGMENTED CORPSES
The article is devoted to solving the urgent problem of forensic medicine - the search for diagnostic markers of common origin of biological objects, which is important in the practice of forensic examination of fragmented corpses in the explosion. The study is based on dermatoglyphic research method, which studied the connection of papillary patterns of fingers and toes. The material of the study was the fingerprints of hands and toes of 169 people (20 prints for each subject, a total of 3380 prints). Persons of both gender, aged 16 to 83 years, of European race, without externally noticeable congenital diseases and markers of pathological dermatoglyphics were examined. The fingerprints of hands and feet recognized arc, loop, curl and transitional types of papillary patterns. Methods of variation statistics and correlation analysis were used to process the data. It is established that informative combinations of pattern types are rare and are mainly observed on the thumbs. For practical purposes, the most significant combination of types of papillary patterns of the thumbs of the right hand and right foot, as well as the difference between the values of the Delta index of papillary patterns of the fingers of one (any) hand and one (any) foot. The developed system of features and criteria for their evaluation allow to exclude the origin of limbs (hands and feet) from one person in about 20% of observations in almost reliable form. Confirmation of the unity of origin of hands and feet is possible three times more often, but at a low level of probability, insufficient for the needs of expert practice.
