April 26, 2019
Author(s)
Edward Sisco, Daniel J. Angelini, Tracey D. Briggs, Michele N. Maughan, Michael G. Feasel, Jennifer W. Sekowski
In the United States in 2016, 64,000 overdose deaths were reported to be associated with the abuse of opioids, including prescription painkillers (e.g. oxycodone), opiates (e.g. heroin), or synthetic opioids (e.g. fentanyl). The recent spike in the

Methods to Characterize 3D Scanners for Forensic Applications

February 22, 2019
Author(s)
Prem K. Rachakonda, Balasubramanian Muralikrishnan
Forensic photography has been one of the most valuable tool for investigators over many decades. They preserve the history of the scene and provide a way for investigators to analyze the scene of interest. However, it is difficult to obtain any objective

A Layered Graphical Model for Cloud Forensic and Mission Impact Analysis

February 1, 2019
Author(s)
Changwei Liu, Anoop Singhal, Duminda Wijesekera
In this paper, we describe a layered graphical model to analyze the impact of cyber attacks on business processes and services. Our model has three layers: the upper layer models the business processes and their dependencies. The middle layer constructs

Author(s)
Erica L. Romsos, Peter Vallone
The Rapid DNA Act, which amends the DNA Identification Act of 1994, allows for the integration of rapid DNA instruments for use by law enforcement for DNA testing of arrestees in a booking station environment. Several parallel efforts have been made to

A Reference Material for Evaluation of Cs-137 Radiochronometric Measurements

August 16, 2018
Author(s)
Kevin B. Lavelle, Richard Essex, Jeffrey T. Cessna, Kevin P. Carney, Cole R. Hexel
A new nuclear forensic reference material has been characterized as a standard for radiochronometric determination of the model purification date for 137Cs sources. The purification date of a radioactive source is a potentially diagnostic nuclear forensic
