Forensic Evidence and Criminal Investigations: The Impact of Ballistics Information on the Investigation of Violent Crime in Nine Cities,

We explore the impact of information from ballistics imaging hit reports on the investigation into violent crimes. Ballistics imaging hits link two crimes involving the same firearm by forensically matching tool marks on the fired bullets or cartridge cases. Interview data collected from detectives who received a hit report were used to explore the relationship between the presence of a hit report and outcomes in 65 gun‐related violent crime investigations in nine U.S. police agencies. Findings indicate hit reports rarely contribute to identification, arrest, charging, or sentencing of suspects, because of delays in producing hit reports. On average, hit reports were completed 181.4 days after the focal crime. This delay forces investigations to proceed without the benefit of information from ballistics analysis. Additionally, hit reports rarely contained detailed information that was immediately useful to investigators. Instead, hit reports required additional research by the investigator to unlock useful information.     

Attitudes,Perceptions, and Preferences of Individuals from Temuco (Chile) About Denture Marking

Denture marking (DM) helps identify edentulous people with different methods. Analyzing perceptions and attitudes of denture wearers would enable understanding of the practical aspects, an analysis still absent in South America. Fifty‐three individual candidates for removable dentures were instructed on disaster victim identification (DVI) and the usefulness of DM for this purpose. They were physically shown eight DM systems and a questionnaire to which they responded by highlighting preferences in those systems. Although 98.11% did not know that dentures could be marked, only 9.43% denied interest in some type of DM. The 90.57% would mark their dentures with some system, preferring the inclusion of QR codes or a micro SIM card. The proven weaknesses of DVI and propensity for disaster mean this community in Chile is an opportunity to implement DM systems. Obstacles may come not from patients but from their dentists, educational institutions, or a lack of public policies.     

The difficult issue of age assessment on pedo-pornographic material

The issue of juvenile pornography has seen an increase in the past few years of the number of expert opinions requested to forensic pathologists, paediatricians and other various experts within the forensic and medical fields concerning the age of represented individuals. Regardless of the entity of the problem, no actual method exists which can allow us to give an objective and scientific answer, particularly in the postpubertal stage. Using parameters related to sexual maturation can be very dangerous. Nonetheless some experts still insist with similar types of “expertises”. This study aims at verifying the ability of different experts in assessing age of postpubertal individuals represented in pornographic material. Results underline the difficulties and major uncertainties of age evaluation by visual observation of photographic material particularly when the subjects have reached the sexual maturation stage – and therefore in verifying whether the individual is above or below 18 years of age (an important age limit for most European countries as far as this type of crime is concerned). Furthermore the study stresses the need both to search for an alternate approach and to apply extreme caution in judicial evaluation.

Psychological Abuse and Depressive Symptoms in Dating Women: Do Different Types of Abuse Have Differential Effects?

The purpose of the current study was to examine potential differential effects of two forms of psychological abuse, emotional/verbal and dominance/isolation, on women's depressive symptoms. It was expected that emotional/verbal abuse would have a direct impact on both concurrent and prospective depressive symptoms among dating women. In contrast, it was expected that the depressogenic effect of dominance/isolation abuse would be moderated by level of perceived interpersonal control. Women who perceived themselves to have high levels of interpersonal control were hypothesized to be less negatively affected by partner dominance/isolation behaviors than their low control counterparts. Although the effects of both types of abuse on concurrent depressive symptoms were relatively weak, more robust longitudinal effects were found. Emotional/ verbal abuse at Time 1 did not predict Time 2 depressive symptoms after controlling for depressive symptoms at Time 1. In contrast, dominance/isolation abuse at Time 1 significantly predicted increases in depressive symptoms over time, and this effect was moderated by level of perceived interpersonal control in the expected direction. Implications for future research and clinical intervention/prevention efforts are discussed.
