Crime Scene Response Team (CSRT)

CSRT’s comprised of specially trained laboratory personnel are available 24/7/365 at all seven forensic laboratories. These highly trained CSRT’s are experts in all aspects of recognition, documentation, collection and preservation of forensic physical evidence. Our ISO/IEC 17025 accredited services also include:

  • Visualization of latent bloodstaining using chemical reagents
  • Bloodstain pattern documentation
  • Trajectory analysis and shooting incident reconstruction

Our laboratories provide crime scene services ranging from consultation up to and including response to mass fatality incidents. Statewide, we respond to 200+ major crime scenes per year.

Evidence collected from the scene is brought back to the laboratory and submitted for laboratory analysis. Crime scene reports are authored detailing the response for use by the criminal justice system, and CSRT personnel are also available to provide expert witness testimony in the discipline of scene investigation.

Our CSRT personnel’s primary job is as a scientist, specialist or technician who works within a forensic discipline in the laboratory. In addition to their laboratory training, they must also successfully complete an intensive 4+ week crime scene training school. Our team members also provide the highest quality training in scene investigation. 

Bloodstain Pattern Analysis

Bloodstain pattern analysis (BPA) is the scientific study of the static consequences resulting from dynamic blood shedding events and the physical properties of blood in motion. It involves detecting, documenting, and analyzing the size, shape, distribution, and location of bloodstain patterns, as well as the relationship among various bloodstains at a scene or on submitted items. Bloodstain patterns from crime scenes and on submitted items can yield valuable investigative information, reconstruct events and support or refute statements made by people associated to the events that created the bloodstain patterns.

Due to the complex nature of BPA, requests are submitted directly to the laboratory and will be evaluated to determine if an analysis is warranted. BPA is available at all our laboratories with approximately 15 cases analyzed per year.

BPA reports are authored for use by the criminal justice system, and analysts are also available to provide expert witness testimony in the discipline of bloodstain pattern analysis.

Our BPA personnel’s primary job is as a scientist or specialist working within a forensic discipline in the laboratory. In addition to their laboratory training, they must also successfully complete an intensive mentor-based training program in bloodstain pattern analysis that also includes the following external training courses:

  • Basic Bloodstain Pattern Analysis Course
  • Advanced Bloodstain Pattern Analysis Course
  • Fluid Dynamics of Bloodstain Pattern Formulation
  • Bloodstain Pattern Analysis of Fabrics
