Forensic Examination of Airsoft Replica Arms
Instructor: Matthew Nodel
This workshop will spend the day reviewing the history, use, development and mechanical design features of Airsoft style guns. Time will be spent covering how to document and test these guns in the forensic environment and the legal implications surrounding the use and possession of such guns. A protocol for the safe handling of these types of weapons will be discussed and techniques on checking the loaded status, test firing and documenting the guns and their accessories from a forensic standpoint will be reviewed. This workshop will culminate with a visit to a local Portland, OR Airsoft store where the participants will get an opportunity to see and handle a wide assortment of these types of guns and accessories.
Latent Print Advanced Testimony workshop
As the scientific reliability of friction ridge evidence continues to be challenged, latent print examiners must be prepared to defend their science in the courtroom. Not only do examiners need to be able to discuss these topics in an admissibility hearing, but they also need to be prepared to respond during cross-examination of trial testimony. The recent National Academy of Sciences report entitled “Strengthening Forensic Science in the United States: A Path Forward,” identified perceived weaknesses in the forensic sciences and has already generated challenges in the courtroom. It is now more important than ever for fingerprint examiners to effectively communicate why, and demonstrate how, friction ridge science is reliable.
This 16-hour course of instruction is designed for latent print examiners. Through presentations and group discussions, students will learn how to demonstrate the scientific reliability of friction ridge evidence during direct testimony and formulate responses to defense-related arguments.
Maximum # of students: 30

Advanced Courtroom DNA Testimony: Maintaining integrity under pressure.
Years ago, DNA typing achieved such wide acceptance and proven reliability that opponents no longer try to discredit the technology itself. Attacks now focus on: (1) the quality and methodology of the laboratory work, including the lab’s error rate; (2) the statistical interpretation of data; and (3) discrediting the DNA witness. Both the Prosecution and Defense employ various strategies to shift, shape, or stain the scientific findings to their advantage. Representatives of both sides will explain and actively demonstrate their courtroom tactics in this workshop, so that the DNA analyst will be able to resist attack, maintain integrity under pressure, and avoid impeachment.
Fatal Fire Death Investigation
It will be an 8-hour lecture with some hands-on examples for those who want to handle examples of burned bone.

Basic IR Blood Photography Techniques / The Fuji IS Pro
Instructor: Jeff Borngasser
This workshop is an introduction to IR/UV-Photography of blood. Demonstrations of how this type of photography differs from conventional photography will be performed. Discussion will cover different lighting and filter conditions and how then can change the image captured. The focus of this workshop will be crime scene photography, however some other techniques may be discussed such as obliterated writing, counterfeit currency, and pattern removal. Individuals are encouraged to bring their IR cameras to participate in hands on exercises.
Please bring your IR camera and a tripod if possible for hands on experience
