Fire investigation

This event brought together practitioners and researchers to enhance information-sharing and promote collaboration among the impression, pattern, and trace evidence analysts, law enforcement, and legal communities.

The symposium was presented by the NIJ Forensic Technology Center of Excellence January 22-25, 2018.

Review the conference proceedings (pdf, 161 pages).

The webinar will introduce those laboratory managers with fire debris analysis sections to the nuances of fire debris analysis. This is the third webinar in the ASCLD Train the Director Webinar Series.

Residential structure fires are predominantly fueled by synthetic contents and commonly become ventilation-limited.  Therefore accounting for the impact of ventilation on fire is important. Examining flow paths within the structure can aide in fire pattern analysis.

The focus of this project was the application and limitations of technology used for fire investigations. Today’s field-portable GC/MS) systems were found to provide lab-quality data for volatile hydrocarbons but the interpretation of that data proved challenging for field operators. Online access to lab experts is essential.  Evidence sampling is enhanced with the use of sensitive Photoionization Detectors (PID) as a supplement to canine searches.
