After comparing the unknown mark and known print the fingerprint expert will make their evaluation. They will weigh up all of the information available as a result of the comparison process and determine whether there is unique agreement between the two to confirm identity beyond all reasonable doubt.
The most crucial aspect of the identification process is the verification element.
This is an independent and complete analysis, comparison and evaluation of both prints which is carried out by a minimum of a further two fingerprint experts. The verification process is the key to the reliability of fingerprint evidence.
It demonstrates that the original conclusions are valid through consistent results from the different experts who have analysed, compared and evaluated the information available in both impressions.
