Over the past 50 years, Sirchie has trained thousands of law enforcement professionals from around the globe. Our Evidence Collection Accelerated Training Program provides you with hands on training with limited class sizes in our state of the art facilities. This class, commonly known as Crime Scene Technology, covers the scientific methods of collection, identification, evaluation, and preservation of physical evidence.
You need to attend this program if:
You process crime scenes
You want to learn more about the latest tools and techniques used to process crime scenes
You want to find as much evidence as possible at the crime scene
Crime Scene Investigation
The various types and categories of physical evidence are reviewed with the emphasis being placed on the proper procedures for securing the crime scene and preparing to collect evidence.
Fingerprint Theory and Classification
The fundamental principles of fingerprints are examined, including the basic concepts of ridge pattern development, identification characteristics and classification methods. Students will review latent print comparison methods with emphasis on understanding AFIS and modern latent print identification techniques.
Fingerprint Development —Powders
The proper use of oxide, metallic, magnetic, and fluorescent powders is discussed. Students will develop latent prints on a variety of surfaces including paper, glass, plastic, and even textured surfaces. Students will experience lifting powder developed latent prints using tape, hinge lifters, gel lifters, and Accutrans. Utilizing photography and light source for proper documentation is reviewed.
Processing Latent Prints with Chemicals
During this segment, students will develop latent prints on porous surfaces, including paper and cardboard, utilizing iodine fuming, ninhydrin and silver nitrate. Students will review proper process sequencing for the maximum retrieval of latent prints and review the chemical principles of how they work. Cyanoacrylate (superglue) techniques for non-porous surfaces will be demonstrated also.
Crime Scene Photography
Procedures and techniques are discussed and demonstrated for properly documenting a crime scene through photography. Also reviewed and demonstrated are key camera settings such as aperture, shutter speed, and ISO, as well as proper accessories and equipment for properly capturing evidence quality photos.
Controlled Substances Identification
Students will work with presumptive field test kits that offer screening of the most commonly abused drugs and narcotics.
Serial Number Restoration
Working with various metallic and plastic surfaces, students will restore obliterated serial numbers. Liquid and gel reagents are used in conjunction with the electron accelerator.
Firearms and Ballistics
Identification of firearms and the fundamentals of ammunition and its manufacture, behavior, and destructive effects is discussed. Fundamentals of gunshot residue, including determining proximity and presumptive testing for GSR are reviewed and demonstrated. Students will also be exposed to basic shooting reconstruction and proper documentation of shooting incidents.
Alternate Lights and RUVIS
The use of alternate light sources to identify evidence at the scene as well as enhance contrast with fingerprint powders and chemicals is reviewed. RUVIS, using the SIRCHIE Krimesite Imager, will be used to demonstrate a non-intrusive technique for discovering latent prints at the crime scene without powders or chemicals.
Students learn proper methods to locate, identify, and collect physiological fluid stains. Proper search methods including alternate light sources and chemical search methods including luminol and Bluestar are demonstrated. Students will also learn how to presumptively identify the type of stain using chemical reagents. Collection and preservation methods will be reviewed based on the latest best practices for DNA.
Proper collection of digital devices, including computers and cell phones, will be reviewed. Students will learn the fundamentals, including data that can be extracted from these devices, the legal aspects of data, and ways to preserve data through proper packaging and Faraday techniques.
Footprint, Tire, and Toolmark Impression Evidence
Impression evidence types and their value in criminal investigation will be reviewed. Students will learn and experience methods for capturing footwear tread impressions, including magnetic powder development, electrostatic dust print lifting, and dental stone casting. Principles of footwear and tire comparison will be shown, including proper documentation for the lab and court.
Review and Final Examination
A comprehensive examination will be given at the end of the course, covering materials discussed and demonstrated.
