The purpose of the Detail is to help keep you informed of the current state of affairs in the latent print community, to provide an avenue to circulate original fingerprint-related articles, and to announce important events as they happen in our field.

Last week
Dennis Degler prompted a discussion on the CLPEX message forum regarding John Doe warrants.

This week

the IAI is in full swing in St. Louis, MO. and an excellent program is ahead of those in attendance.

This week, we review an article on:

Process errors leading to missed Identifications

Recognizing the potential for error is the first step in eliminating it. The possible causes of missed-ID's has been studied. A comprehensive list of mistakes should be compiled that includes oversights, errors, omissions etc that could lead to a suspect not being identified in a case where a detectable latent print capable of individualization was present.

Below is a list of all the ones I could think of, grouped by which stage of the process at which they occur.

I'd like people to comment on whether they think the errors are caused by lack of proficiency on the part of the operator, by unsound judgment by the decision-maker or are unavoidable in some or all circumstances. Also, can you think of any errors I have missed?

Evidence recovery

The scene is not examined by a CSI

A surface that bears a detectable latent print is not examined

The surface is not examined using the appropriate method for development of the latent

The latent is not optimally developed

The developed latent is not noticed by the CSI

The developed latent print is not recognized as a friction ridge print

The developed latent print is not recorded or recovered



The latent is incorrectly assessed as containing insufficient detail for individualization

Features of the latent are incorrectly classified as friction ridge features or as distortion artifacts

The latent is orientated incorrectly

The digit/palmar determination and search allowances do not include the correct location for the friction ridge skin



The corresponding exemplar is not compared with the latent

The selected target(s) from the latent is (are) not present in the exemplar

The target group is not recognized when seen in the exemplar

Incomplete comparison of all the features available



Under-evaluation of similarities

Over-evaluation of dissimilarities
