Paint evidence is often submitted in hit and run cases in order to develop investigative leads leading to the arrest of the driver. Also paint from tools used in burglaries may be matched to paint on windows and doors of the crime scene. In this course, we will cover the chemistry of paint and microscopic techniques used in the forensic investigation of common paint samples submitted to the crime lab. Hands on exercises will include stereo and compound microscopy and infrared microscopy. Discussion of use of scanning electron microscopy and Raman microscopy as well non-microscopic techniques are included.
This course includes pre- and post-course modules as part of our blended learning program.
See below for course outline and additional information.
• The proper collection and preservation techniques of paint evidence
• Chemistry of automotive and architectural paint
• Identification and thickness measure of paint layers
• Use of infrared microscopy to determine the polymer matrix of the paint layers
• Use of scanning electron microscopy and Raman microscopy for pigment and filler determination
• ASTM methods for paint analysis
• Recommended reporting and testimony guidelines for presentation of paint evidence.
Criminalists who are working with trace evidence.
Students are expected to successfully complete a variety of tasks in the form of hands-on exercises, laboratory exercises, identifications of unknowns, and quizzes. Students are notified at the end of the course whether or not they have successfully completed the requirements of the course based on:
Upon successfully meeting these requirements, a student is awarded a certificate of completion and CEU credits, if available. Those who have not successfully passed the course requirements do not receive a certificate or CEU credits.
