New Paradigm for Fingerprint Reporting

Overview In November 2015, the Defense Forensic Science Center (DFSC) issued an Information Paper announcing the decision to cease the use of the terms “individualization” and “identification” in latent print technical reports and expert witness testimony. This webinar provided an…

Magneto-Optical Sensor Roundtable

Overview The discovery of more effective methods to detect and restore erased markings in firearms is of great interest to firearm examiners, in particular the invention of new nondestructive methods. Magneto optical (MO) sensor technology may address this need. Earlier…

Latent Fingerprints: Reducing Erroneous Exclusions

Overview This presentation discusses reducing erroneous exclusions in latent fingerprints. The exclusion decision is a fairly recent change in latent print comparisons, and the discipline is still struggling with how to handle exclusions. Erroneous exclusions are being discovered with surprising…

Latent Fingerprints: Developing Methods and New Technology

Overview The first presentation given by Mark Dadmun is titled: Developing Methods to Improve the Quality and Efficiency of Latent Fingermark Development by Superglue Fuming. The second presentation given by Igor Pacheco and Brian Cerchiai titled: A Research Study for…

Fluorescence of Blood Impressions with Acid Yellow

Overview Blood impressions are associated with serious crimes against people, and are frequently recorded in the blood of either the perpetrator or the victim, often establishing a close connection in time between the two. A certificate of completion is available…

Fingerprint Identification: Reliability and Accuracy

Overview New technology is constantly being tested by Researchers and Developers to help this vital tool move forward in today’s society. These new technologies will assist in furthering the accuracy and reliability of using latent fingerprints. Our featured presentations for…

False-Positive and False-Negative Error Rates in Cartridge

Overview This webinar was presented to discuss the results and implications of an error rate study of cartridge case comparisons. The study was designed to measure false positive and false negative error rates of examiner comparisons of fired cartridge cases.…

Error & Uncertainty in Bloodstain Pattern Analysis

Overview This presentation provided a general introduction to the concepts of error and uncertainty as well as the differences between them. It will then apply these concepts to quantitative and qualitative aspects of bloodstain pattern analysis. Error and uncertainty are…

Demystifying Vacuum Metal Deposition [Archival]

Overview This course is directed to Crime Scene Investigators, Bureaus of Identification, and Forensic Science Laboratory Examiners. The information will help departments justify the cost of a Vacuum Metal Deposition (VMD) and demonstrate to the fingerprint industry that VMD has…

Collecting Footwear and Tire Impressions in Snow

Overview From footwear to tire to snowmobile impressions, snow impressions can provide extremely valuable evidence in helping to resolve criminal investigations. Unfortunately, photographing and obtaining a cast of a snow impression is often a challenge for the crime scene examiner.…
