DNA Fingerprints Facial Prints and Other Digital Forensics as Evidence in Criminal Investigation and Court Proceedings

Abstract

The purpose of this paper is to focus on the legitimacy and importance of digital evidence such as
fingerprints, DNA, polygraph, auto-radiography, and facial-prints and their admissibility in
investigations and court proceedings. The extracts from criminal databases are also relevant in this
context. The modus operandi of criminals, particularly in case of repetition of similar type of
offence is also of immense significance. Normally, the criminals operate adopting a specific
manner or method. The killers have their own way or mode of committing the offence. The modus
operandi changes from person to person or groups to groups in committing the offences. It may
determine that the offence is committed by a group or an individual. In view of its impotence, the
modus operandi must be included in criminal databases as a separate column. The criminal images
sketched by artists on the bases of description of witnesses present on scene of offence have
relevance and must be included in the criminal databases for future reference and use.
