WORKSHOP

Advanced Crime Scene Search Techniques Using the Crime-lite AUTO

This hands-on workshop provides a comprehensive exploration of advanced light techniques for forensic evidence detection and visualization. Participants will examine the strategic application of alternate light source (ALS) technology to locate and enhance biological fluids, latent fingerprints, and gunshot residue (GSR) across a variety of substrates. The course extends beyond foundational ALS use, introducing specialized illumination techniques tailored to specific evidence types. Oblique lighting will be demonstrated for the enhancement of three-dimensional surface detail, including impressions and textured evidence, while coaxial illumination will be utilized for the examination of latent prints on flat, reflective surfaces. Additional approaches include reflective ultraviolet (UV) imaging, as well as infrared (IR) fluorescence and IR reflectance to reveal otherwise obscured or invisible evidence.

The workshop will also address the integration of ALS with dye-stained fingerprints, emphasizing how proper wavelength selection and filtration can significantly improve contrast and visualization. Through practical exercises and scenario-based applications, participants will develop a systematic and methodical approach to crime scene searches, improving both detection efficiency and documentation quality.

This training is designed for forensic practitioners seeking to expand their technical proficiency and fully leverage the capabilities of the Crime-lite AUTO in operational environments.

LECTURE

Building Latent Fingerprint Database with Multiple Substrates and Development Techniques

Latent fingerprint imagery is a current challenge area in biometric and forensic applications due to the image quality issues caused by the variation in surfaces on which latents can be deposited, as well as the techniques used to develop latent fingerprints. While algorithms and latent fingerprint examiners should be trained on a wide variety of latent prints, the number of latent fingerprint research datasets is extremely limited and most of the available datasets consist of just a few substrates and development types. The goal of this project was to create a latent fingerprint and palmprint image dataset collected from 150 individuals using a variety of curved and flat substrates (porous, semi-porous, nonporous, and adhesive materials) and imaged using a variety of development techniques (1,2-indanedione, ninhydrin, cyanoacrylate fuming, dye stain, Wetwop, etc.). In addition, ground truth ink & paper finger and palmprints have been collected along with livescan and contactless imagery.

Participants had to leave clean prints (washing hands and waiting 5 minutes), sweating prints (heated hands in gloves for 5 minutes), and sebaceous prints (touching oily parts of the face/neck area). Repeated fingers and parts of the palm were collected after each phase on various substrates. Imaging of developed prints were performed by using a DCS-5 imaging system and RUVIS, both from Foster and Freeman. A total of 9 400 images of developed latent prints were collected from the 150 participants. Each image was assigned to a unique number correlated to the participant, which substate was used, developing technique and finger number or part of the palm. All images were taken in a lossless file format (RAW). All inked ten prints and palm prints were captured with Aware AFIX software using an Epson Perfection V850 Pro scanner, scanning at 1000dpi. 
Researchers and trainers can now use the dataset to compare efficiency and effectiveness of comparing unknown prints with 3 different tenprint sets (inked, livescan and touchless) and be presented in the form of ROC curves.

Why Do We Ignore Great Design? 

With 15 years of experience using the Foster+Freeman Digital Capturing System (DCS), I can confidently say it is the most reliable and intuitive forensic tool I’ve ever operated. In forensics, the value of a streamlined workflow is often overlooked, but well-designed equipment should make your job easier. This system has significantly cut my processing time without sacrificing quality, making the forensic imaging process both efficient and genuinely enjoyable.
