Blood Stain Pattern Recognition, Interpretation, and Preservation / Shoe Print Evidence
DATE: September 25th, 2013
LOCATION: Harrisburg Area Community College (Harrisburg, PA)
This full-day workshop was designed as an introductory course in recognizing, identifying, and preserving the factors and forces that create blood stain patterns and shoe print evidence. It included hands-on exercises such as preliminary tests for blood, collection of blood stain patterns by tapelift, shoe print matching, and the detection of semen stains via tactile senses only (eyes closed and one hand behind the back, literally).

This workshop included an Angle of Impact Guide, which can be printed on transparency film and used as an overlay to provide the investigator with a crude approximation of the angle of impact. Please be sure to either cover the stains with tape or clean off the guide between each use.
This workshop included a document that can be used as both a scale and a worksurface for examining evidence.
Lastly, there was a brief section discussing iPhone apps that can be used at crime scenes or in the laboratory. Go to "Resources", then "For Law Enforcement", then "Favorite iPhone Apps".
