Fatalities due to intoxicated arrestees jumping out of moving police vehicles

Fatalities resulting from emergency vehicle crashes are relatively rare. Mortality, particularly in the case of unbelted occupants, is relatively high. Data on drunken (handcuffed) arrestees jumping out of a moving police vehicle or the circumstances of such events have not been published. Two cases of such fatalities are described in this paper. Since these cases should be considered as "death in custody," may give rise to significant covering and speculation in the media, and may raise liability questions, they require an in-depth medicolegal investigation, including investigation of the crime scene, complete medicolegal autopsy/toxicology, and reconstruction of the event in the presence of an experienced forensic pathologist. From the 2 cases described in this paper, it appears that mechanical malfunctioning of the locking device of the door of the police vehicle and lack of controlling the actual lock-tied closing of the vehicle door (instead just assuming that it happened) may precipitate such cases. Auditory control by the police officers of the arrestee tampering with or manipulating the car door may be hampered by the background noise of the police vehicle, the on-board radio, and the use of a siren. Regular visual control and adequate control of the actual locking of the vehicle door are of paramount importance to prevent such mishaps. Reconstruction of the event in the presence of the forensic experts is mandatory to test the different hypotheses of the fatal event.     

Dental age estimation through volume matching of teeth imaged by cone-beam CT

A custom-made voxel counting software for calculating the ratio between pulp canal versus tooth volume based on cone-beam CT tooth images was developed and evaluated. The aim of this study was to attempt establishing a correlation between the chronological age of a certain individual and the pulp/tooth volume ratio of one of the teeth. Twenty-eight single rooted teeth of 19 individuals with well-known chronological age were scanned by the cone-beam CT (3D Accuitomo, J. Morita, Kyoto, Japan). Next the images were analyzed using the custom-made software. Linear regression analysis was performed. The results of the analysis showed a moderate correlation between the pulp/tooth volume ratio and biological age with a coefficient of determination (R2) of 0.29. Although the present work was limited to a pilot study, the developed technique showed promising results for dental age estimation in a non-invasive manner using cone-beam CT images in living individuals.     

Developments in US Anti-terrorism Law: Checks and Balances Undermined

The thesis of this update on developments in US anti-terrorismlaw since 9/11 is that the system of checks and balances amongthe several branches of the government, executive, judicialand legislative, has been undermined by the deferral and avoidanceof key decisions by each of the branches and the withdrawalof authority by one branch from another. Examples are drawnfrom four Supreme Court decisions handed down since 9/11; theuse of sunset clauses in the USA PATRIOT Act; the Detainee TreatmentAct of 2005; the use of torture in interrogating suspected terrorists;National Security Agency electronic surveillance; extraordinaryrenditions of suspected terrorists; and the Military CommissionsAct of 2006.     

Crime scene investigations using portable,non-destructive space exploration technology

The National Institute of Justice (NIJ) and the National Aeronautics and Space Administration's (NASAs) Goddard Space Flight Center (GSFC) have teamed up to explore the use of NASA developed technologies to help criminal justice agencies and professionals solve crimes. The objective of the program is to produce instruments and communication networks that have application within both NASA's space program and NIJ programs with state and local forensic laboratories. A working group of NASA scientists and law enforcement professionals has been established to develop and implement a feasibility demonstration program. Specifically, the group has focused its efforts on identifying gunpowder and primer residue, blood, and semen at crime scenes. Non-destructive elemental composition identification methods are carried out using portable X-ray fluorescence (XRF) systems. These systems are similar to those being developed for planetary exploration programs. A breadboard model of a portable XRF system has been constructed for these tests using room temperature silicon and cadmium-zinc telluride (CZT) detectors. Preliminary tests have been completed with gunshot residue (GSR), blood-spatter and semen samples. Many of the element composition lines have been identified. Studies to determine the minimum detectable limits needed for the analyses of GSR, blood and semen in the crime scene environment have been initiated and preliminary results obtained. Furthermore, a database made up of the inorganic composition of GSR is being developed. Using data obtained from the open literature of the elemental composition of barium (Ba) and antimony (Sb) in handswipes of GSR, we believe that there may be a unique GSR signature based on the Sb to Ba ratio.

Discretionary Justice: Decision Making in a State Juvenile Parole Board

The literature in Criminal Justice is replete with commentary on both the virtues and injustices associated with adult parole board decision-making. There has been far less attention paid to juvenile parole boards in part because so few of them exist. Institutional release decisions in most states still remain the purview of juvenile institutional staff members. This paper examines parole Authority decision-making in a citizen-dominated state juvenile parole board. The paper focuses on the conduct of hearings, dispositional guidelines, criteria used by board members in decision-making and the advocacy role of parole officers and institutional staff. The influence of deinstitutionalization and least restrictive policies on parole Authority decision making is also discussed. During recent years, the literature in criminal justice has become replete with commentary on the virtues and injustices associated with parole board decision-making. Consequently, many questions have been raised about disparate sentences, the criteria used by parole boards in making decisions, unstructured discretion, and the pressing need for guidelines and statistically accurate parole prediction instruments. The intent of this paper is to examine parole decision-making in a state juvenile parole board where individualized treatment and rehabilitation have been long standing goals. The paper focuses upon the criteria used by board members in decision-making, the conduct of hearings, the guideline system used to determine a recommended length of confinement and the advocacy role of parole officers and institutional staff. The influence of deinstitutionalization and least restrictive policies on parole board decision-making is also discussed. The author is presently completing the second year of a two-year appointment as a member of the Parole Authority under discussion. Since December, 1983, the author has continuously observed and participated in approximately 300 individual parole hearings over thirty-seven hearing days.
