Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year. 相似文献

Microscopic characteristics of hacking trauma 总被引:1,自引:0,他引:1

The purpose of this study was to determine if it is possible to associate machetes, axes, and cleavers with the microscopic parallel striations they leave on the cut surfaces of the bone. Hacking trauma was experimentally inflicted on pig bones using machetes, axes, and cleavers. Negative impressions of both the cut surfaces of the bone and the weapon blades were analyzed using scanning electron microscopy. The results of this investigation indicate that it is possible to correlate a class of hacking weapons to trauma inflicted on bone by these weapons. 相似文献

Little is known about the adolescent risk factors and young adult health-related outcomes associated with running away from home. We examined these correlates of running away using longitudinal data from 4,329 youth (48% female, 85% white) who were followed from Grade 9 to age 21. Nearly 14% of the sample reported running away in the past year at Grade 10 and/or Grade 11. Controlling for demographics and general delinquency, running away from home was predicted by lack of parental support, school disengagement, greater depressive affect, and heavier substance use at Grade 9. In turn, runaways had higher drug dependence scores and more depressive symptoms at age 21 than non-runaways, even after taking these antecedent risk factors into account. Runaway status did not predict alcohol dependence risk at age 21. Results highlight the importance of substance use and depression, both as factors propelling adolescents to run away and as important long-term consequences of running away. 相似文献
