E-mail edward.hueske@unt.edu Text: Criminalistics – An Introduction to Forensic Science by Richard Saferstein, 10th Edition (or later), Prentice-Hall. Course Description: This course is an introductory survey course in criminalistics. The focus will be on the recognition, collection, preservation and analysis of physical evidence. Students will be presented with the theories and principles relating to the primary techniques utilized in the analysis of physical evidence with the presumption that most of the students do not have extensive scientific backgrounds (i.e. chemistry, biology and/or physics). The goal of this class will be to provide students with a basic understanding of what criminalistics entails and to prepare them for additional, more in-depth classes in criminalistics/ forensic science. This class is the first in a series of three criminalistics classes. The course includes hands-on lab exercises in the criminalistics lab located in Chilton Hall 275 and in 250 SRB (check schedule to see which location for each lab) as well as some exercises that will be posted on-line (Blackboard). Learning Objectives: Upon successful completion of the course, the student should be able to: 1. 2. 3. 4. 5. 6. 7. 8. Aug 31 Explain the goal of physical evidence in the criminal justice system Specify what the field of criminalistics encompasses Identify the capabilities of crime laboratories with regard to the examination and analysis of various types of physical evidence Understand the limitations of crime laboratories with regard to various types of physical evidence Distinguish criminalistics from the other areas of forensic science Recognize the inter-relationships between criminalistics and criminal investigation Accomplish more advanced studies in criminalistics and forensic science Understand the application of the scientific method to the analyses of items of physical evidence Introduction; Definition and scope of Forensic Science; The Scientific Method (chapter 1) Locard Exchange; Legal considerations in forensic science, The CSI Effect ; Reading assignment: Read chapters 1-3 in text.

Nov 16 Footwear/Tire Tread Evidence (handout); “Investigating FW”. Lab 10 – Footwear Comparison (CH 275) Nov 23 Crime scene reconstruction Nov 30 Ethics in forensic science Dec 7 Dead Week (review) Dec 14 Final Examination Exams/Grade Computation Exams: There will be 3 exams, and a final given during the semester. Exams will consist of multiple choice, short answer, and/or true/false. The exams will cover all assigned materials. Make-up exams will not be given. Labs: There will be 10 lab exercises, 3 of which are at-home assignments. Lab exercises carried out in the criminalistics lab (either CH 275 or SRB 250) are to be turned in at the end of the lab sessions. Take-home labs are to be turned in to the lab TA at the next lab session scheduled (the firearms ID exercise will be completed online). There will be no makeups for missed labs. Grade Computation: Your final grade will simply be determined by taking your cumulative total (+ 10 LABS) and dividing by the total possible (multiplied by 100 to convert to a %). A – 90% or better B – 80-89% C – 70-79% D – 60-69% F – 59% or less. By simply keeping a 2 column tally (1 column for the points possible and the 2nd for the points you earn) you may determine your grade at any point in the semester (i.e. divide total points earned by total possible and multiply by 100). Attendance Your registration fee buys you the right to occupy a seat in the classroom during the scheduled hours of the class. Whether you choose to occupy that seat is your decision. However, if you choose not to attend class you must accept the following consequences: 1. You will miss information that is not available in the text or elsewhere that you will be responsible for on exams. 2 2. 3. Missing a class (lecture or lab) means missing an entire unit (e.g. fingerprints, trace evidence, etc.). You may not make-up any missed exams or lab work. It is recognized that there are going to be legitimate reasons why class/lab cannot be attended. For that reason, the lowest lab score (presumably a zero for non-attendance) will be dropped. Classroom courtesy and decorum You are requested to abstain from texting, e-mailing, making internet searches, etc. during class. If you are unable or unwilling to comply with this request, please do not come to my class (I will be happy to recommend an addiction counselor if you fall into the “unable” category). Such activities fall under the heading of “Class Distractions” in the University guidelines and will be dealt with accordingly. “The Bottom Line” – I intend to come to class on time and prepared, give you my full attention and treat you with courtesy and respect. I expect nothing less from you. Cheating Students suspected of cheating will be dealt with according to University guidelines On-Line materials, announcements, etc. All power point presentations used in class will be posted on Blackboard and available prior to the class they are presented in. Additionally, special assignments, reading materials and announcements will also be posted. You should check the site at least the day prior to each upcoming class: http://webctvista.unt.edu/ Extra Help Students desiring extra help with the lecture material or who have questions, are advised to consult with the TA’s or to come by my office either during my regular office hours or by appointment Useful websites The following websites are particularly pertinent to this class: You will find information that will expand on the lecture material and the text as well as provide you with some insight into career opportunities in criminalistics at these websites. www.aafs.org - American Academy of Forensic Sciences www.firearmsid.com - Forensic firearms website www.afte.org - Association of Firearm & Tool Mark Examiners www.swafs.org – Southwestern Association of Forensic Scientists Special Instructions for the On-Line Microscopy Exercise (Feb 17) You are to complete the following 3 tutorials: Magnifying microscopy, Stereo microscopy and Polarized light microscopy. You are to answer the following questions and present a hard copy to the lab TA by 5:00 p.m. Monday, Oct 4: Magnifying Microscopy – There are 6 samples to be examined at 6 different magnifications. Prepare a chart that indicates which particular color is found at the center of the crosshairs for each sample/magnification. What do you think is responsible for any changes in color that you observe? 3 Stereo Zoom Microscopy – List the samples that are provided. At what magnification are you able to see as much of both of the eyes of the insect sample? At what magnification can you see only 1 complete (distorted somewhat) hexagon for the packing foam? Polarized Light Microscopy – Which of the samples is most likely present in copious quantities on the beaches of South Padre Island in March of most years? Which 3 samples show mostly shades of yellow, tan, black and blue under crossed polars? Which sample has a feather-like structure? 4
