III.   Course (Catalog) Description

Course provides instruction in protocols and techniques for forensic crime scene analysis, as well as hands-on experience using alternate light source and solid-state lasers.  Topics include techniques in the examination of blood spatter, ballistics, and impression evidence, along with procedures in forensic mapping and the use of GPS for outdoor crime scenes.

IV.   Learning Objectives

  1. Identify responsibilities of a forensic technician.
  2. Explain and demonstrate the methods of forensic mapping.
  3. Illustrate methods of searching for clandestine graves by ground and airborne methods.
  4. Explain and demonstrate physical evidence collection and preservation of DNA evidence.
  5. Demonstrate the science of fingerprint mechanics, discuss locating latent prints by spectrographic viewers, and analyzing the different chemical development techniques for developing latent fingerprints.
  6. Demonstrate the safe operation in advanced applications of a 4 watt TracER forensic laser.
  7. Exhibit the applications and operation of various alternate light sources.
  8. Contrast techniques for impression evidence, blood stain pattern evidence, ballistic and tool marks.

V.    Academic Integrity and Student Conduct

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),

VII.  Methods of Instruction

Course includes lecture, demonstrations and lab work.  Outdoor field exercises/labs will be performed.  The course may include guest speakers and or optional tours of law enforcement agencies/labs.  Materials include various media, criminal investigation tools and kits, electro-optical aids, infrared and ultraviolet viewers and various types of forensic light sources.

Course may be taught as face-to-face, hybrid or online course.

VIII. Course Practices Required

Students will be expected to prepare for class by reading assignments, drawing crime scene information with the use of total station, operating thermal imaging equipment, developing latent fingerprints by chemical processes, comparing impression evidence, and providing direct examination of actual evidence.  Students will participate in a critique of these assignments to develop analytical and deductive skills.  Course is taught face-to-face.

IX.   Instructional Materials
