Basic Crime Scene Investigation
This program is designed to instruct patrol officers and detectives in the techniques needed to properly process scenes of crimes
such as burglaries, thefts, auto thefts and vandalisms. These types of scenes are frequently passed over by local police
departments due to lack of equipment and resources and often are not serious enough to warrant summoning County or State
Police Crime Scene Units. Departments that process their own crime scenes routinely have a much higher clearance rate for these
types of crimes because of suspect identifications.
It is also important to know what can be done by a full Crime Scene Unit. Trained department level crime scene investigators will be
able to identify conditions that must be preserved as "major scenes" pending the arrival of the Crime Scene Unit.
Topics Covered
Fingerprinting
How to detect, develop and collect latent fingerprints at crime scenes using basic and inexpensive brushes, powder and tape and
chemical processing methods using ninhydrin and cyanoacrylate. The function of AFIS (Automated Fingerprint Identification System)
will also be covered.
Photography
How to properly photograph crime scenes and injuries to victims, police officers and suspects. Prosecutors are elated to find that a
crime scene has been photographed and that injuries are properly recorded as photographs make it much easier to describe
scenes to juries. Proper photographic training also improves documentation of Domestic Violence victims' injuries. Students who
have simple point and shoot cameras will be shown how to use them to heir fullest capacity.
DNA
Did you know that most State Crime Labs will accept DNA evidence on any type of crime? At present, local departments are
submitting DNA evidence properly collected from crime scenes that is being compared with DNA samples which every prisoner has
to submit when incarcerated. As the number of prisoner samples increases, we should see a dramatic increase in DNA "hits" over
the next few years. This training includes a DNA module covering what can be found at a crime scene that can contain DNA, how to
properly collect and package DNA evidence at the scene, what your lab can do with the evidence you collect and collecting
exemplars from suspects. The National DNA database (CODIS) is also explained. Collecting DNA samples can be as easy as
equipping a trained officer with inexpensive sterile swabs and distilled water.
Tips and techniques
Search and seizure issues regarding crime scene investigations are covered.
We also cover how to use some common household items in evidence collection. For example, you can buy 8x10 plastic laminating
sheets at office supply stores for 50 cents each that work great when lifting a print of a whole hand often found on the inside of a
glass door, left as a suspect flees after a robbery. Those sold by police vendors may cost as much as $10.00 each.
Instructors will demonstrate toolmark casting, footwear and tire impression casting, blood spatter pattern recognition and bullet
trajectory reconstruction.
Course Structure and Fees
Each day will consist of a morning classroom session and an afternoon practical, hands-on session. All equipment is provided by
LETC for the class however departments that have processing kits, digital cameras and laptop computers should send them with the
students so that they can learn to be familiar with their own equipment.
The cost for this 16 hour, two day course is $295.00 per student.
