  • Lead Homicide Recertification  (20 hrs. credit)


This is a 20-hour course that ends at 12:00 Noon on May 9th.

Blood found on crime victims, suspects, or witnesses (clothing or persons) is significant and should be treated as important evidence when investigating crime scenes.  Bloodstain pattern analysis may provide investigative leads as well as supportive or non-supportive evidence for statements from victims, suspects, and witnesses.

This course will give investigators and crime scene specialists a basic foundation in identifying and documenting bloodstain pattern evidence at crime scenes.  It will provide the basic tools needed to establish parameters in bloodstain pattern identification and crime scene reconstruction, and will serve as a foundation for additional observations and experiments involving bloodstains.  Participants will learn how to properly document and preserve evidence so that others will be able to reconstruct what occurred.  Course instruction will include case presentations and practical lab work.
