Gunshot Residue Identification
From Tuesday, April 04 2017
To Sunday, April 16 2017
Every day

 Sponsor: Hooke College of Applied Sciences

Description: The Gunshot Residue analysis by SEM/EDS course emphasizes hands-on learning. Using two SEM instruments, students have the opportunity to study test samples provided by our staff, under the direction of McCrone scientists with over 15 years of combined SEM/EDS Gunshot Residue analysis experience.

During the course, students learn through lecture, demonstration, and hands-on participation: theory of the SEM and EDS systems, how to setup and operate SEM and EDS instruments for GSR analysis. The students will be introduced to and participate in discussions of the ASTM E-1588 and SWGGSR guidelines for SEM/GSR analysis, interpretation of data, reporting conclusions, preparing for expert witness testimony. Students will set up overnight GSR analysis runs using either the JEOL JSM 6480LV SEM with Oxford Instruments INCA EDS system or the ASPEX 3025 SEM/EDS system. This course provides a foundation for students new to SEM and EDS. At the end of the GSR course, students with no prior experience are able to align an SEM, obtain secondary electron (SE) and backscatter electron (BE) micrographs, and perform EDS qualitative and quantitative analysis. For students with prior experience, we emphasize procedures and strategies to optimize the GSR analysis and data reduction.

Court Case Update

FINGERPRINT EVIDENCE went through a nearly three-year ordeal in the New Hampshire court system, but eventually emerged unscathed. On April 4, 2008, the New Hampshire Supreme Court unanimously reversed the decision of a lower court to exclude expert testimony regarding fingerprint evidence in the case of The State of New Hampshire v. Richard Langill. The case has been remanded back to the Rockingham County Superior Court.
