Résumé
Background: Positive identification of living/ deceased using distinct traits is a cornerstone of forensic science. According to Locard’s principle “When two objects come into contact, there is always transfer of material from one to another”. The finger prints, lip prints and blood remains are the evidence for forensic identification. Aim: To study the frequency, distribution and association of ABO blood groups, finger print pattern, lip print pattern among gender and also the inherent nature of patterns among family members. Materials and Methods: A total of 200 Subjects (100 males, 100 females) within the age range of 17- 30 years and 20 families were randomly selected and aggregated as groups. Lip prints and finger prints were collected using dusting technique with fine carbon powder. ABO blood group was determined by slide agglutination method. Results: Ulnar loop - Males - Vertical, Radial loop - Males - Branching, Whorl - Females - Branching, Arch - Males - Intersecting; Females - Vertical. O positive, B positive - Loop - Branching, A positive - Loop - Vertical and Intersecting, AB positive - Whorl - Branching and Intersecting. Among 20 families, 14 families showed 100 percent pattern resemblance. High percentage of similar pattern was observed between father to daughter (70%) in finger prints and mother to son in lip prints (71%). Conclusion: Correlating the uniqueness of these physical evidence helps in personal identification as it can narrow the search & to substantiate the facts where there is little evidence
