Abstract

Personal identification is the primary aim of anyforensic investigations. Foot impressions, either 2D or 3Dare used for person identification. Foot impression found on soft surfaces is three dimension in nature (3D),also namedfoot outline which shows the boundaries of the foot left by the offenders on soft surfaces. It is afact that 3D impressions can also be used to determine stature, body weight and gender. In the developingcountries, people are still walking barefooted. Earlier foot impression studies were conducted on mixedpopulation and currently researchers are insisting the importance of ethnicity consideration.MalaysianIndians are an important ethnic group living in Malaysia, with minor sub-ethnicgroups such as Malayali,Telugu, Sikh, Tamil, and others. Hence this study intends to examine the relationship between stature and 3Dfoot lengths among Malaysian Telugus, mostly living in peninsular Malaysia. The stature and foot outlines(3D) were collected from consented Telugu 140 subjects, comprising 73 males and 67 females, age rangingfrom 18 to 60 years old. The data obtained were analysed statistically using SPSS software version 21.0.There exists a strong positive correlation between stature and 3D foot impression lengths and the correlationcoefficient (R) values are found to be higher in unknown gender/pooled samplefollowed by males andfemales. This study developed regression formulae to determine stature from foot outline (3D) lengthsamong Malaysian Telugus for crime scene investigation. The equations are population specific and shouldnot be used for any other populations.

Abstract

Footprint is a physical evidence, often found at the crime scenes. Due to its ability to provide moreinformation than fingerprint, it has been considered as a valuable clue. Sometimes, partial footprints or toeprints are found in crime scenes. Hence the present study used toe prints among Kagay-Anons of Philippinespopulation for gender determination. A total of 4000 toe prints were collected and analyzed by “Acreemethod”, using 5mm x 5mm square area transparent film. The number of ridges within the square wascalculated as ridge density. The finding has shown that females havecomparatively higher ridge density thanmalesin all five toes. The present study shows that partial foot print found at the crime scene can be stillcollected and analyzed for identification

Abstract

Hand morphology and fingerprint patterns form a valuable tool for person identification. Sex identificationis a vital role in forensic and medico legal investigations. Determination of sex or gender of an individual isimportant because it can help in the forensic investigators to identify the suspect if male or female based onthe ridge density of handprint or palm print. The present study used fingerprints collected fromKagay-anonpopulation for determination of gender through ridge density. A total of 4000fingerprints (200 males and200 females) were collected and analyzed using the “Acree” method of ridge density counting within 5mmx 5mm square area calculated the ridge density. The mean ridge density iscomparatively higher in females(12.39-14.14) than males (11.06-11.87) in the fingerprints of the study population. The results are presentedin the form of tables and graphs.
