• What does the process of collecting, analyzing, reporting and interpreting fingermark evidence in the criminal justice system look like internationally?

• What can we learn from each other?

Methods

Interviews, questionnaire, 3D-experiments

Would you like to participate in this study? Please leave your name, email address and organization & function title.

Curious about the 3d-experiment?

Try it yourself!

Provide an overview of

- current situation of the collection, analyses and interpretation of fingermarks in the Netherlands - the needs and opportunities in fingermark practice - the possibilities for the implementation of new fingermark

opportunities

- an international comparison of fingermark use

Several methods will be used:

Ø Literature review Ø Observations Ø Interviews Ø Questionnaires

Ø Analyzing files of criminal investigations Ø Analyzing court files

Ø 3D-experiment Ø Vignette study

PhD study: Full use of latent prints – Beyond the lines

Objectives

Method

Currently, focus in latent fingerprints is only on the friction ridge patterns.

However, research has shown there is more information in latent prints:

New information from fingermark prints:

Ø Chemical analyses of fats and acids left in a fingermark print - information about e.g. DNA, diet, drug use, medicine use Ø The position of fingermarks - information on activity level Two PhD students study the chemical information and activity level of fingermarks.

This study creates an overview of the current situation and future possibilities of fingermark evidence.

Background

VISUALIZING THE FINGERMARK

• When is a fingermark suitable for evidence?

• What other information can be found in fingermarks?

• How can information on activity level be used in the interpretation of fingermarks?

Methods

Interviews, observations, questionnaires, analyzing criminal investigation files, literature review

SEARCH WITH AFIS (HAVANK)

• How is the current identification process?

• What is the influence of new techniques on this process?

• Fingerprint experts as advisors at the crime scene?

Methods

Interviews, literature review

EVIDENTIAL VALUE WEIGHED BY THE JUDGE

• What is the ultimate value of fingermark evidence in criminal cases?

• How does a judge weigh fingermark evidence?

• Knowledge of judge on fingermark evidence?

• How is new information from fingermark evidence assessed by the judge?

Methods Interviews, vignette

JUDGING ALL EVIDENCE IN A CRIMINAL CASE

• How do police detectives and public prosecutors value fingermark evidence?

• How do police detectives and public prosecutors value new information from fingermark evidence?

• Role fingermark evidence in criminal cases, and compared to other types of evidence?

Methods

Interviews, vignette, 3D-eperiment

FORENSIC REPORTS ON FINGERMARK EVIDENCE

• Current state of fingermark evidence reports?

• Interpretation of these reports by police, public prosecutors and judges?

• How to report new information from fingermarks?

Methods

Interviews, literature review, vignette SEARCH FOR LATENT PRINTS AT THE CRIME SCENE

• What leads a crime scene investigator (CSI)?

• Focus of CSI’s on fingermarks?

• Focus of CSI’s on fingermarks with less identification value?

Methods

Interviews, observations, 3D-experiment, literature review
