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.

Updated the RSW-Plus Training Page with new dates.

Updated the Fingerprint Interest Group web page with FIG # 11.


Last week

We introduced Charlie Parker's Fingerprint Interest Group (FIG) distortion examples.  There will be a new example posted each week with a reference in the Weekly Detail.

This week

we look at the Ridgeology Science Plus! workshop. 

Ridgeology Science Workshop - Plus!

This workshop is a 40-hour course that provides the same format as Glenn's "Ridgeology Science Workshop," with a new twist: he has brought with him a second instructor! Josh will be equipped with a scanner and laptop to provide each student with one-on-one help with difficult comparisons, as they are working their comparison exercises.

The class combines detailed lecture on the scientific bases for friction ridge identification with intense practical exercises emphasizing correct comparison techniques. Lecture topics include the philosophy and “ACE-V” methodology of comparing and identifying latent prints. Students are equipped to explain the reasons behind the fundamental principles of permanence and individuality through a special emphasis on human embryological friction ridge development and friction ridge skin structure. Training is also given in the recognition of ridge pattern “clues” to help students identify which finger or which area of skin made a particular latent impression. Related topics include an introduction to "Daubert" issues, the recent US v. Plaza ruling, permanent intentional fingerprint mutilation and non-friction ridge skin comparison and identification.

This is an excellent course to help the student prepare for the IAI certification exam. Comparison exercises using real inked prints and latent lifts reinforce the lectures. Students do not automatically work on the same exercises. Each student is evaluated and assigned personal exercises that are challenging, but achievable. Individual attention is given during exercise periods. It is an ideal class, even for senior examiners who desire to increase their speed and accuracy in doing latent print comparisons.

This training is also valuable for AFIS technicians who lack traditional latent print comparison training or experience. Students learn how to evaluate friction ridge features ignored by AFIS and how to use those features in searching inked prints and making identifications.

This is an intermediate level class. Although every effort will be made to accommodate persons new to the field, some foundation in latent print matters is strongly recommended prior to taking the class. Students are expected to be familiar with fingerprint terminology and should also be doing some latent print comparisons on the job. Each student must bring a latent print comparison magnifier(s) and ridge counters.

About the Instructors:

Glenn Langenburg is currently employed by the Minnesota Bureau of Criminal Apprehension as a certified latent print examiner and crime scene investigator. Glenn earned a BS in Forensic Science from Michigan State University in 1993 and a MS in Analytical Chemistry in 1999 from the University of Minnesota. Currently he is a PhD candidate in the Forensic Science program at the University of Lausanne, Switzerland. His thesis research involves the statistical analysis of fingerprint comparison methodology.

Josh Bergeron is an IAI certified latent print examiner and a member of the Minnesota BCA crime scene team. He graduated from Concordia College in Moorhead, MN, where he received an ACS (American Chemical Society) Chemistry, Bachelor of Arts degree. He has been an instructor of basic and advanced latent fingerprint courses since 2001, has conducted research on the development of bloody fingerprints on dark surfaces, and has published work in the JFI. His most recent research involves developing a fluorescent superglue and using liquid nitrogen to separate duct tape.

The last course of 2007 will be presented in Mesa, Arizona from December 10 through 14.  The course is already over half full, so fax a registration form to (520) 514-7766, or contact or (888) 235-1230 for additional details.
