Validation of image stream hashing: A forensic method for content verification
J Forensic Sci. 2023 Dec 1. doi: 10.1111/1556-4029.15432. Online ahead of print.ABSTRACTHow 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. An image stream hashing method was recently introduced to the forensic science community to answer the question above. This paper offers an initial validation study of image stream hashing method that may answer the question above. The first half of the study's ...

Pathway to terrorist behaviors: The role of childhood experiences, personality traits, and ideological motivations in a sample of Iraqi prisoners
This study examines a cross-sectional sample of incarcerated men convicted of terrorism in Iraq (N = 160). A questionnaire-guided interview included adverse childhood experiences (ACEs), conduct disorder (CD), antisocial personality disorder (ASPD), religious and political ideology, views about causes of terrorism, and the severity of terrorist acts. Path analysis was employed to examine the relationships between these factors and to identify the model with the best fit. After adjusting for age, employment, and location, results indicated that ACEs positively impacted CD, ASPD, religious guidance, and terrorism attitudes. ...

The systemic error in the vertical component of handgun bullet trajectory reconstructions
J Forensic Sci. 2023 Nov 30. doi: 10.1111/1556-4029.15431. Online ahead of print.ABSTRACTEstablishing 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 vertical offset are explained and calculated for 10 different handgun/ammunition combinations over a range of distances up to 100 m. The presented results are intended to provide forensic firearm examiners with a reference frame for the magnitude of error intro...

A "concrete" identification in a dismemberment case
J Forensic Sci. 2023 Nov 30. doi: 10.1111/1556-4029.15428. Online ahead of print.ABSTRACTHomicide 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 obstacles, specifically related to identification. Various approaches to obtaining fingerprints from decedents encased in concrete have been suggested and implemented over the years. The presented case is that of an initially unidentified 44-year-old male, who was sub...

The relationship between pellet size and shotgun dispersion patterns
J Forensic Sci. 2023 Nov 30. doi: 10.1111/1556-4029.15427. Online ahead of print.ABSTRACTWhen 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 in the incident. But sometimes examiners will have to resort to alternatives, such as using cartridges of the same brand and type but with another pellet size. For this reason, the relationship between pellet size and shotgun dispersion patterns was studied with...

Cervicothoracic junction in disaster victim identification: Idiosyncrasies and relevance of body position for advanced chest radiograph comparisons
J Forensic Sci. 2023 Dec 1. doi: 10.1111/1556-4029.15436. Online ahead of print.ABSTRACTStandard 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 records of other body regions. For example, chest radiographs concern subtler morphological varieties of smaller anatomical features across a larger number of skeletal elements in contrast to frontal sinus comparisons that concern a large, (often) single, highly vari...
