Physical Characteristics of Spatter Stains on Textiles Compressed

Diciembre 2023

It is well-known that bloodstain pattern analysis (BPA) on textiles is difficult and subject to many errors or misinterpretations. In this webinar, we probe the reason for this and suggest useful information that a bloodstain pattern analyst may be able to extract from the observed bloodstains. The data set demonstrates the roles of drop volume and impact speed in bloodstain formation on textiles.

This webinar was hosted by the NIJ Forensic Technology Center of Excellence on December 12, 2023.

Dr. Frances Scott, NIJ scientist and program manager, continues the conference discussion with two fellow panelists: Ciena Bayard, the Method Development and Validation Program Manager for D.C. Office of the Chief Medical Examiner, and Haley Greene, the Deputy Epidemiologist for the Central Region for the Virginia Department of Health. Read the transcript.

Validation of a Confirmatory Proteomic Mass Spectrometry Body Fluid Assay

Diciembre 2023

While forensic DNA analysis can identify an individual(s) at a crime scene, it cannot identify the biological source from which that DNA was obtained – e.g. blood, saliva, or semen. Identification of the biological source of DNA can provide important contextual information for forensic investigations as well as evidence in court. Nearly all current methods used for body fluid identification are presumptive. Here we present a new proteomic mass spectrometry method for the confirmatory identification of blood, saliva, and semen.
