NIJ (National Institute of Justice) -Innovations in Technology to Advance Forensic Science
Tuesday, March 09, 2021: 8:30 AM - 11:05 AM
Speaker(s)
Description
Forensic Science is the application of science to criminal and civil laws, mainly during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure. Any field could technically be forensic, certain sections have developed over time to encompass the majority of forensically related cases. A potential for forensic application of new discoveries and developments made recently in various fields of science and technology will be discussed. The session will be of great interest to researchers from academia and national laboratories as well as engineers from industry since the technological advancements in law enforcement is a priority area in the US and around the world. Significant investments has been made recently to advance the development of new technology for forensics and security at the federal level in the US. Several funding agencies including NIJ, DOD, NSF and NIH (illicit drugs) make significant investments in research and development programs in the area of forensic and security.

The ability to identify menstrual blood has important implications in the criminal justice system, however, the ability to distinguish menstrual from circulating blood poses distinct problems for forensic scientists. Unlike the more commonly tested forensic body fluids, blood, saliva and semen, which have easily identifiable, abundant marker proteins due to...

The identification of an ammunition manufacturer based on the analysis of gunshot residue (GSR) discovered at the crime scene can provide valuable forensic information for the investigation. Vibrational methods, such as photoacoustic (PAS), attenuated total reflectance Fourier transform infrared (ATR-FTIR) and Raman spectroscopy, are highly selective and nondestructive analytical techniques...

The potential of soil analysis is not being realized in modern forensic laboratories. Soil can associate an unknown specimen from a shoe, tire tread, or shovel with a known, but also can provide investigative leads. Although numerous cases have demonstrated this capability, criticisms of forensic soil analysis (e.g., subjective, labor-intensive,...

Sweat is a biological fluid that contains a variety of metabolites and other low molecular weight compounds, our group is using number of those for non-invasive sensing purposes. The concentrations of the biochemical content within an individual's sweat are controlled by hormone metabolism processes that fluctuate daily based on factors...

Identification of ignitable liquids in fire debris samples relies on comparison of chromatograms and mass spectra from the debris sample to those of reference liquids. To account for evaporation, reference liquids evaporated to different levels are often included in the comparison. However, as experimental evaporations are time- and resource-intensive, an...

This study developed a reliable screening of inorganic and organic gunshot residues using laser‐induced breakdown spectroscopy (LIBS) and electrochemical screen-printed carbon electrodes. The methods are capable of detecting GSR in just a few minutes with high specificity and sensitivity. The proposed approach provides a novel alternative to identifying gunshot residues...
