The 28th conference of the Northwest Association of Forensic Scientists was held in Tacoma, Washington September 26-30. Scientists from Washington, Idaho, and Oregon gathered to share research and exchange ideas. Karen taught an 8 hour workshop on Wednesday dealing with the reproduction of bloodstain patterns. Lecture topics included the scientific method, proficiency testing and the recent NAS report. For the hands-on portion students used pig blood to re-create bloodstain patterns and test their hypotheses regarding the deposition bloodstains. The students were enthusiastic with their experiments and their eagerness to learn contributed to making the class a success (note: Should a crime occur in a certain room at a certain Tacoma hotel, a field test for porcine blood on observed bloodstains may help reduce confusion later in the lab).
