Call for Road-School Hosts

Anja Einseln
Training Officer
Quality Assurance and Training Unit
FBI Laboratory
Quantico, Virginia

In conjunction with its continuing training efforts, the FBI Laboratory would like to offer the forensic community the opportunity to host a road school. The hosting laboratory would foster a networking opportunity for neighboring laboratories, while receiving instruction at no charge from FBI Laboratory staff as part of the road-school process.

One frequently requested school is Gunshot Residue (GSR). Class size is limited to 14 students, and host laboratories are required to open the course to neighboring agencies. The course description is provided below. Laboratories interested in hosting this class should contact John Webb of the FBI Laboratory Firearms-Toolmarks Unit at john.webb@ic.fbi.gov or + 1-703-632-7236.

Gunshot Residue School

This five-day course introduces students to methods of muzzle-to-target distance estimation based on the analysis of GSR patterns on clothing. During the class, students are given a series of practical problems, which get progressively more difficult. Using the Modified Griess, DTO, and Sodium Rhodizonate tests, participants develop GSR patterns on simulated evidence, then shoot test patterns using provided firearms and ammunition.

This course is designed for firearms examiners and trainees who are familiar with handling and using firearms and who need more experience and training in conducting GSR examinations.
