Forensic disciplines combine to develop new fingerprinting technique that could help spot document fraud.

New forensic approach utilises existing tools to determine when a fingerprint was deposited on a questioned document.

As one of the foremost innovators within the fields of fingerprint evidence and forensic document examination, researchers at foster+freeman have plenty of combined experience when it comes to developing new technologies for the investigation of crime. However, while it is not un-common for existing methods and techniques to be re-purposed or enhanced to improve results, it is rare that two independent forensic disciplines combine so well as is the case with the company’s latest invention – a unique gelatin fuming technique for examining fingerprints on documents.

Combining a common fingerprinting practice (known as gelatin (gel) lifting) with a novel fuming technique (previously used to reveal fingermarks on fired ammunition) the new technique can be utilised by investigators to determine the sequence in which print details and fingermarks were added to a document.
