Our fingerprint experts can evaluate any form of fingerprint evidence and advise whether procedures have been followed in a correct manner, whether identifications are correct and that the latter are case relevant.
We are often asked to assess the nature and orientation of fingerprints on, for example, packaging items containing drugs or examine the interiors of motor vehicles.
Alongside this, is access to laboratory facilities that enable the development of fingerprints on numerable items that may have been touched by an individual. This service is particularly useful in cases where, for example, the Crown may not have undertaken any of their own tests.

At the outset such evidence was used just for the confirmation of identity but it was soon realised that persons left their fingerprints at crime scenes, whether it be in the latent form or within a contaminant and that these to could be matched.
Over the ensuing century methods have changed, as technology has changed and the police now have a computer system which generally allows them to compare fingerprints from anywhere within the nation, and obviously much more quickly than the previous manual method.
During the same period, techniques for finding fingerprints have also expanded with the finding of a range of techniques where the powder and brush will not give a good result. There are now available physical and chemical techniques including lasers and light sources which can be used when the surface is “difficult” and whilst there are surfaces where fingerprints cannot be found the application of the correct treatment to the surface will assist.
