Crime Scene - The Crucial Minutes
THE CRUCIAL MINUTES presents advanced evidence techniques in a simplified and enjoyable format. Investigators, Evidence Technicians, Criminalists, and First Response Officers will gain enhanced information from crime scenes and pick up new ideas and techniques.

This class has received high acclaim from all who have attended. It's for everyone who wants to competently process a crime scene. It's for anyone who has ever felt overwhelmed or intimidated by the complexity of a crime scene.

THE CRUCIAL MINUTES is a one-week, 40-hour class designed for officers and technicians who have total responsibility for processing a crime scene. The first day's lecture includes the identification and collection of physical evidence. During this segment of the class, issues are discussed such as first arrival responsibilities, securing the scene, conducting a preliminary survey, photography (both still photos and video), legal considerations, crime scene search methods, interrelationship of various types of crime scene documentation (photos, sketches, and notes), collection and packaging of evidence, latent fingerprint considerations and final evaluation of the scene to assure completion of tasks.

The second day of class is spent in a more detailed study of latent prints, including lecture, demonstrations, and class exercises. Day three covers bloodspatter including velocity considerations in interpreting the bloodspatter, formulas for determining angle of impact, cast off blood and back spatter, and transfer patterns. A practical exercise of blood spatter to determine angle, convergence, and origin is included.

Day four includes discussion and practical exercises on gunshot residue/trace metal detection and footwear/tiretrack documentation and casting. Trace metal topics include shortwave UV light exam, pattern observation, and documentation. Gunshot residue topics cover proper swabbing techniques and common reasons for conflicting and inconclusive results. Footwear/tiretrack topics include protecting the impression, photography techniques, dental stone casting, dustprint lifting, sketching, and conclusions about footwear/tire track impresssions. The final day of class is spent processing a mock crime scene.

The need for DNA Training

Law enforcement and State prosecutors are clamoring for information about DNA evidence--how to collect it, how to maintain it, and how to use it in the courtroom. A well-meaning police officer may irreparably degrade DNA evidence by placing crime scene evidence in the hot trunk of a police car for days. By all accounts, police officers everywhere are eager for information about collecting and processing DNA evidence before it gets to the crime laboratory. When the National Institute of Justice issued a pamphlet called `What Every Law Enforcement Officer Should Know About DNA Evidence,' the first printing of one million copies was gone after just five months. Training should be a matter of course for all law enforcement. No rape kit will lead to the perpetrator if the evidence is collected improperly.

Training must also be available for all prosecutors. The subcommittee heard testimony on this topic from the Vice President of the National Association of District Attorneys, who stated:

Prosecutors who advise law enforcement agencies and forensic laboratories, as well as actively try cases involving DNA, need to be fully versed in the capabilities, and vulnerabilities of this technology. This is not something you learn in law school nor is it something that most of us can `bone up on' the night before trial. DNA technology is complex. Training in the use of DNA evidence in a criminal investigation or a trial is crucial.
