Fingerprint Examination Department

Fingerprint Identification Unit

In this Unit, experts aim at determination whether finger marks secured at crime scenes match the fingerprints (reference material) collected from suspects.

The following properties of friction ridge characteristics are used in identification process:
  • uniqueness (unique arrangement for each individual),
  • immutability (arrangement of features remains unchanged during lifetime),
  • irremovability.
Fundamental tasks of Fingerprint Identification Unit include determination of:
  • person, who left fingerprints at a scene of crime
  • person, who left lip print at a scene of crime
  • person who left ear print at a scene of crime
  • how a glove impression was generated.
Lip print and earprint examinations are performed solely in the CFLP Fingerprint Department. In order to confirm their competence, experts of this Unit regularly participate in proficiency testing in the area of fingerprint identification, organized by external institutions.
Fingerprint experts supervise the recruitment process for experts-to-be. To facilitate the whole process, guidelines for the conduct of testing in fingerprint identification were developed, consultations are provided, in addition to trainings and in-house apprenticeship for candidates on the way to a final exam.
Every year, proficiency testing is performed for regional police fingerprint units according to the “Conduct of proficiency testing through interlaboratory comparisons in the area of fingerprint identification” procedure. This is done with a view to ensure high level of forensic casework. Fingerprint identification experts take part in interlaboratory cooperation programmes, organised within ENFSI (European Network of Forensic Science Institutes) Fingerprint Working Group.
