Validation of image stream hashing: A forensic method for content verification

How do forensic examiners know if they have altered an image stream when converting a digital image from one codec or file container to another for analysis? Forensic standards and best practices recommend avoiding alteration or degradation of multimedia data during transcoding. ...

Pathway to terrorist behaviors: The role of childhood experiences, personality traits, and...

Radicalization to terrorism is a multifaceted process with no single theory or approach to explain it. Although research has focused on understanding the process, there is still a dearth of studies that examine an empirically driven pathway to terrorism behavior. This study exami...

Cervicothoracic junction in disaster victim identification: Idiosyncrasies and relevance...

Standard plain film medical radiographs often form a valuable line of evidence to identify individuals in large‐scale fatality events. While commonly available, chest radiographs present a challenge that their analysis is somewhat more involved and complex than radiographic recor...

The relationship between pellet size and shotgun dispersion patterns

When reconstructing a shooting incident with a shotgun, the muzzle‐to‐target distance can be determined by relating the size of a dispersion pattern found on a crime scene to that of test shots. Ideally, the test shots are performed with the weapon and ammunition that were used i...

A “concrete” identification in a dismemberment case

Homicide perpetrators can use concrete as a means to conceal their victims. When concrete encasement is encountered in the forensic field, albeit rarely, it is often coupled with postmortem dismemberment. This method of obscuring the evidence presents unique investigative obstacl...

The systemic error in the vertical component of handgun bullet trajectory reconstructions

Establishing the path or trajectory of a fired bullet is an often recurring part of shooting incident reconstruction. The current study describes how gravitational pull causes a systemic error on the vertical component of a trajectory reconstruction. Bullet drop, drop angle, and ...

A rapid and non‐destructive identification for paper cup evidence based on shifted...

In order to achieve rapid, non‐destructive, efficient, and accurate classification of paper cup samples, we propose a classification model that integrates shifted‐excitation Raman difference spectroscopy (SERDS) with self‐organizing map (SOM) and Bayesian optimization–support vec...

Microscopical recognition and characterization of solution dyed fibers

Solution dyed fibers are synthetic fibers colored through the addition of insoluble pigmentation to the polymer prior to extrusion. This is in contrast to most textile fibers, which are traditionally colored via immersion in liquid dyebaths following extrusion. Solution dyed fibe...

Forensic examination of security features of the CDC‐issued COVID‐19 vaccination card and...

During the COVID‐19 pandemic, the United States released the CDC‐issued vaccination card to document the status of immunizations. It eventually was used as a verification system to allow patrons to safely access public venues. This is/was apparently a simple printed piece of pape...
