Concluding Remarks

Workshop A: CSI Photography

Instructor: Dave Pauly

Location: Lecture classroom and Photo classroom

Lesson I: Exposure Triangle – attendees will be exposed to the photographic principles of aperture, shutter speed, and ISO. They will learn how these factors interact and how they are used in crime scene photography. Practical exercises for each side of the triangle and an overall exercise involving a mock crime scene will be used to demonstrate these principles.

Lesson 2: Evidence macro-photography – various factors must be considered when photographing evidence for comparison purposes. Forensic photographers must employ macro methods for fingerprints, footwear, tool marks, trace evidence, and other comparisons. This lesson will review how evidence for comparison must be photographed and attendees will conduct practical exercises performing this method.

Workshop B: Biological ID

Instructor: Jim Gocke

Location: Lab classroom

Lesson I: Blood is a common biological fluid present at crime scenes, but many times it is not completely visible or what is visible is not blood. This lesson will review chemical methods used to search for, identify, and enhance blood evidence at the crime scene. Each attendee will participate in demonstrations and actual exercises involving the three key steps.

Lesson II: Alternate Light Sources are used to search crime scenes for biological evidence and also use to enhance pattern evidence for photography. The participant will learn the scientific background of why ALS works for visualization of evidence and will be exposed to examples of practical uses in the field through hands on exercises.


Workshop C: Impression Evidence

Instructor: Jim Gocke

Location: Lab classroom

Lesson I: Footprints are the most overlooked evidence at most crime scenes. The contain evidence that can lead to the identity of a suspect through careful retention and comparison. Attendees will learn the keys to footprint comparison and how evidence can be recovered. Students will participate in practical exercises involving casting and electrostatic dust print lifting.

Lesson 2: Impression evidence extends beyond the most common fingerprints, footprints, and tire marks. Identification of tools and weapons used to enter a building or usCSed as a murder weapon are also critical to forensics. Impression marks found at the scene can be cast and compared to items received at the scene or away from the scene, tying them to the crime. Attendees will review the various techniques and also have an opportunity to cast various tool marks and items with different casting compounds, comparing the practical use of each for forensics.


Workshop D: Ballistics and Shooting Reconstruction

Instructor: Dave Pauly

Location: Lecture classroom

Lesson I: Gunshot residue (GSR) is used in forensics for two purposes, determination of distance from which the shot was fired and to identify persons that used a firearm or were in the vicinity when it was used. The physical and chemical characteristics of GSR will be reviewed as well as the methods used to determine distance and identification of GSR. Attendees review GSR patterns for distance determination and also conduct a presumptive test for GSR identification.

Lesson 2: After a shooting occurs, there are witnesses that tell the story of what happens. During shooting reconstruction the goal is to reconstruct the trajectories of the projectiles and analyze the paths to support or refute witness testimony. The lesson will include a basic introduction to firearms and ammunition and will provide detail in projectile size estimation, proper scene documentation, and methods for calculating and visualizing bullet paths. Attendees will participate in a trajectory reconstruction exercise, estimating projectile size and path, and if a given scenario is probable or not.
