This class will be held at the Valparaiso Police Department 355 S Washington St Valparaiso, IN 46383 December 11-15, 2023.
Crime scene photography remains one of the most important aspects of any criminal investigation. Whereas notes and sketches document items of interest that the investigator recognizes and records, a properly trained crime scene photographer will record everything of significance at a crime scene that is visualized in the viewfinder. A permanent recording can prove invaluable days, months, and even years after the crime scene has been released by law enforcement. Failure to obtain images while at the crime scene, or in a laboratory setting, that properly portray the item(s) of evidence in the lab, or piece of evidence at the scene, will likely result in the photograph not being accepted by the court, and thus being deemed unsuitable for presentation to the jury.
Forensic Investigation (Evidence Discovery, Collection, Processing & Preservation)
The goals and objectives of the Crime Scene Investigator is the collection, preservation, packaging, transportation, and documentation of physical evidence left at the crime scene. With this evidence, a connection can be made between the victim, the scene, and the perpetrator of the crime. The base goal of this course is establishing methods and best practices for assessing, developing, collecting, and preserving the physical evidence.
Attendees learn proper set-up and crime scene documentation including photography and evidence marking / identification. Through lecture and practical exercises, proper methods are taught for discovery and lifting of latent fingerprints using powders, applicators, tape, chemicals, and other tools. Footprint and footwear evidence, often overlooked, is reviewed and methods for search and recovery are taught. Discovery and sampling of biological evidence, so critical in today’s forensic investigations for its DNA content, is reviewed with practical exercises with best practices for collection and preservation. Attendees also learn the proper packaging and preservation of various types of evidence, including bagging, boxing, labeling, and other methods. The course covers the forensic toolbox and the factors that lead to choosing certain methods.
Impression Evidence: Identifying and preserving footwear, tire mark, and toolmark evidence
Perpetrators are frequently aware of fingerprint and DNA evidence, and they wear gloves and facial/head coverings to avoid leaving this evidence. At the same time, they almost always walk through the crime scene leaving footwear impressions at the scene, and when they leave, they take and keep their footwear evidence with them. This presents a special opportunity and challenge to crime scene examiners to find and preserve the latent impression evidence remaining at the scene.
Attendees learn procedures to discover, enhance, and capture footprint, footwear, and tie mark evidence using various tools and photography. They learn to identify class and individual characteristics present in footwear and tire mark evidence and how it ties the perpetrator/vehicle to the scene. Through practical exercises, footprint capture with powder, electrostatic dust print lifting, and casting are experienced. The module also explores advanced techniques, such as casting in a water, snow, and on unusual surfaces. In addition to footprints and tire marks, attendees learn about toolmark evidence, often found on breaking and enterings, including casting techniques.
Photography: Advanced Techniques Including ALS, UV, and IR for forensic investigation
Photography is used to document most crime scenes today, yet only the most basic techniques are sometimes utilized missing possible key evidence or not providing the true story of the crime scene or evidence. Moving beyond this, attendees of this instruction module learn how to properly document in the preferred – manual mode, and learn to control the exposure triangle in various situations using techniques that reveal evidence once hidden. Utilizing the triangle, dark scenes, shadows, and bright ambient light can all be overcome with specific techniques to show the scene as the investigator sees it.
Attendees through hands on exercises using DSLR cameras and various lenses combined with filters explore various lighting possibilities, using a variety of alternate light sources and filters to build contrast and reveal pattern evidence. Light sources outside the visible spectrum, such as ultra-violet and infrared, reveal body fluids and pattern evidence of gun shot residue and bodily fluids not visible to the naked eye. The camera is shown to be a tool to gather much more evidence than can be seen or documented with any other method.
