Range Of Detective & Forensic Services


1. Questioned Document Examination

"Questioned" document refers to any signature, handwriting, typewriting, or other mark whose source or authenticity is in dispute. Some kind of documents that come under the examiner's purview include wills, contracts, letters, fake certificates, ration card, threatening letters, suicide notes, ransom notes, passports, licenses, photocopies and the like. Forensic Document Examination, is an established field of scientific study primarily meant for identification of forgery as well as to establish the authenticity of documents in dispute.

Questioned Document Examination has played a major role in investigating criminal and non-criminal cases like murder, forgery, corporate crimes, counterfeiting, organized crimes and sex crimes.

Case Study :

A known business personality approached VIS to investigate about fraudulent withdrawal of huge sum from his personal bank account over past few months. He informed us that signature on these cheques are very similar to his but its not him who has signed these cheques. As it was his personal bank account, he suspected someone from family.

After through investigation we zeroed down on few including his own son whose handwriting was matched with that of those cheques. Our client was shocked beyond imagination, he never suspected his son as he was already paying him good amount of pocket money.


2. Fingerprinting Examination

Marks and impressions left at a crime scene vary in there value of individualisation. The types of marks that may be identified at a crime scene will be fingerprints (from the tips of the fingers and thumbs), palm prints and any marks made by skin present on the soles of the feet. Other types of marks or impressions that may also be present at a crime scene are footwear marks, tyre marks and tool marks.

Any mark and impression evidence that appears to be fingerprint, palm or foot related is dealt with by the Fingerprint Bureau. In general each of the Fingerprint Bureau is based at Police Headquarters.

Mark enhancement is the enhancement of latent (undeveloped) marks so they become visible. This is achieved by using different techniques such as lighting conditions, applying powders, applying chemicals or a combination of all of the above. Fingerprint enhancement is dealt with by the Chemical Enhancement team who are generally based within Police Headquarters.

Fingerprint identification is based on the assumption that all fingerprints are individual and immutable (i.e. they never change). Therefore when an identification is made, it is with the assumption that the suspect and no other possesses the fingerprint.

The identification of a fingerprint is basically a comparison and match of two marks.

Traditionally it was the manual comparison between a mark from a crime scene and the fingerprint of a suspect. However since the introduction of the National Automated Fingerprint Identification System (NAFIS) which is now IDENT1 (which was introduced in 2005) computerised comparisons and identifications have now been made. Procedure varies from bureau to bureau although it is still known for suspect comparisons to be made prior to the mark being submitted to NAFIS, if the suspect names are available.

Case Study:

The results of a forensic examination can have very serious implications for the accused in an investigation and forensic scientists must show high levels of competence and integrity.
