Success Story: Advancing the Forensic Analysis of Ignitable Liquid Fuel Fires

National Institute of Justice and JENSEN HUGHES Date February 2018 Overview Investigating fires with “liquid fuel” is particularly challenging, as the combustion of building materials often conceals the presence of the fuel. JENSEN HUGHES, led by Dr. Daniel Gottuk, evaluated…

Detection of Organic Gunshot Residue Using Capillary Microextraction of Volatiles with Cryofocusing

Date July 2017 Overview Researchers at Florida International University’s (FIU’s) International Forensic Research Institute evaluated the capability of capillary microextraction of volatiles (CMV) to extract the volatile organic compounds (VOCs) that constitute organic gunshot residue (OGSR) on the hands of…

Evaluation of Existing Technologies for Novel Analysis and Probabilistic Interpretation of Organic Gunshot Residue

Date July 2017 Overview Firearms exposure has traditionally been monitored by screening for the presence of inorganic particles prevalent in gunshot residue (GSR). These inorganic compounds are associated with the primer in ammunition. Recent research efforts have explored alternative approaches…
