Although the forensic sector has not been well developed in India, it has had a vast effect in other countries that have helped them in a lot of solving cases and discovering innovations. New researches, discoveries, and innovations always happen there that can set a new path for us too.
Recently, the researchers at United Kingdom’s Loughborough University have developed an interesting and new discovery that can give a boost to solving crimes where defendants do not know a sheet of paper.
Huh, not understood? Ok, no worries, let’s read the article further to know about that sheet. Fingerprints play a crucial role, not only in differentiating a person but how would it be when a case is solely relying on just a pattern of someone’s finger?
There arises many cases where the innocent does not know some documents or papers but the case takes a 90° shift against them because of their fingerprint imprinted on that paper. The newly discovered innovation would help to identify whether the text was printed before or after the fingerprint was imprinted on the sheet of paper which can help defendants easily get out of stupid cases.
The technique has been developed by professor Paul Kelly with his former Ph.D. student, Roberto King. He told that normal techniques or devices normally tell about the presence of a fingerprint but his newly developed technique would be confirmed if the text was printed before or after the fingerprint was imprinted.
Developed at Foster + Freeman’s labs at Loughborough’s world-class science and enterprise park, LUSEP, the professor used gelatin pads in his technology.
The process involves placing a thin layer of gelatin pads over any fingerprint imprinted on a sheet of paper along with the text. The layer is gently removed and placed in a vacuum chamber and filled with sulfur dinitride vapor, which reacts with the sample.
The results come up with two options; either as a masked fingerprint, indicating the text was printed before the imprinting of the fingerprint, or completely masked, indicating that the text was printed after the fingerprint was imprinted.
The benefit of using this method is that the text and/or the fingerprint will not be lost, that is, the content of the document will not be damaged and therefore it can be used for further forensic testing if needed. In conclusion, the method can be used in future fraudulent cases.
