Individualizing characteristics of footprints in Gujjars of North India--forensic aspects.

Careful examination of foot impressions can provide important evidences and clues in a crime scene investigation. The present study is conducted on a cross-sectional sample of 1040 adult male Gujjars inhabiting the sub-Himalayan region of North India. The study describes the utility of individualizing characteristics of footprints in forensic examinations. Various features of the toes, humps in the toe line, phalange marks, flatfoot condition, pits, cracks, corns, etc., were studied. Frequency of some of these characters has also been recorded. The frequency of the tibialis-type foot is the highest, followed by fibularis-type, then intermediate-type and midularis-type is found to be least frequent among the sample. Three humps have been found most often in footprints, followed by two humps, four humps, and then five humps and one hump are found to be least frequent. Flatfoot condition is found to be present in 1.54% of the sample population and the trait also shows bilateral variation. Phalange marks, crease marks, pits, deformity, etc., are also demonstrated with suitable examples in the present population. These characteristic features can provide useful clues to establish personal identity whenever complete or partial footprints are recovered at the crime scene and can help in including or excluding the possible presence of individual at the scene of crime.
