The estimation of time since the latest discharge of pistols and revolvers has been achieved by the Solid Phase Microextraction (SPME) sampling technique and the GC/TEA analytical system. The TEA2 compound, which in our previous work (1) was observed in barrels of shotguns and rifles as well as inside spent cartridges, was also detected in pistols and revolvers. The amount of this compound was very low in short-barreled small arms and its escape from the barrel could generally be measured for only a few days or up to two weeks after the latest discharge. To improve the detection of TEA2 compound, the SPME sampling time was prolonged and fibers coated by Carboxen/polydimethylsiloxane were used. The decrease of the TEA2 peak with time after shooting from pistols is nonexponential but the curve-fitting procedure proposed for the estimation of time since discharge of shotguns and rifles is difficult to apply as the decay is very rapid. Therefore, the detection of TEA2 compounds in small arms should be interpreted that the firearm had been used very recently. The amount of volatile decomposition products of smokeless powder increased significantly with the length of the barrel when firearms of the same caliber, but with different barrel lengths were investigated.  相似文献

De‐identified wound data from 197 homicidal gunshot postmortems were obtained between 2000 and 2008. Forensic ballistics data were only available for cases between 2004 and 2008. Males represent 91% of gunshot victims and were struck in the thorax/abdomen with an average of 2.3 bullets. The type of firearms involved were semi‐automatic pistols in the predominant caliber 9‐mm Luger and assault rifles in caliber 5.56 × 45 mm and caliber 7.62 × 39 mm Soviet, using full metal jacket bullets. The majority of shootings occurred at ranges of 1 m or greater. The most common bullet path was front to back in 66% of cases. Entry wounds occurred more often on the left side of the thorax, abdomen, and back. The most common critical organs/tissues to sustain bullet trauma in descending order were as follows: heart, lungs, liver, aorta, spleen, kidneys, and vena cava. Ribs were struck by most bullets that entered the thorax.  相似文献

Abstract: The 2007 exhumation of three children’s graves, located in rural upstate New York and dating to 1979 and 1980, was warranted as their mother had come under suspicion for the death of a child she had been babysitting in late 2006. The local March weather conditions had been wet, and heavy rains fell during the 2‐day process of casket removal. The extremely wet soil and the poor preservation of two wooden caskets increased the likelihood of damage to evidence. After remains’ transport to the forensic center, an indoor wet‐screening station was established so that skeletal elements could be (i) separated from soil matrix and (ii) preserved carefully for analysis. Not only were the remains relatively small and fragile in comparison with those of an adult, but two of the three remains were known to be fire damaged, thus the use of special laboratory preparation techniques was crucial.  相似文献

Wounds of high‐energy centerfire rifles and shotguns represent distinctive injuries of forensic importance. Previous studies of contact wounds have shown variability in the potential of these weapons to produce bursting wounds of the head. The present study analyzed contact head wounds owing to 26 centerfire rifles and nine shotgun slugs and compared them with respect to weapon, ammunition, entry wound site, and projectile kinetic energy. The bursting effect, defined for this study as disruption of at least 50% of the head, occurred in 25/35 of cases and was related to kinetic energy. Bursting was associated with energies <2700 ft‐lbs in 12/22 cases and energies >2700 ft‐lbs in 13/13 cases. The volume of gunpowder gas injected into the wound was considered as contributing to the bursting phenomenon. There was no relation of bursting to the specific entrance wound site, type of ammunition, or projectile fragmentation.  相似文献

Abstract:  This study investigates the legal status of modified shotguns in Turkey by examining the cases submitted to the Aydın Regional Criminal Laboratory between January 2006 and August 2008. A total of 351 shotguns used in crimes were examined. These guns were evaluated in respect of their type, size, caliber, fitness for use, and legal classification. Eleven percent of these shotguns had been modified and it was found that 55% of the modified shotguns were classified according to law 6136 and qualified as a pistol and 45% were classified according to law 2521 and qualified as nonstandard shotguns. Within the Turkish criminal justice system, a nonstandard shotgun attracts a less stringent sentence than a pistol. It would therefore appear that this sentencing structure is considered when modifying shotguns in Turkey. This is clearly a loop-hole in the legislation that could perhaps be investigated and closed.  相似文献

Given the prevalence of rimfire and centerfire rifle usage in both suicidal and homicidal cases, there is a paucity of articles in the literature that focus specifically on rifle wounds. Gunshot wounds, in general, have been extensively studied with articles focusing on the types of injuries, weapons used, wound locations and weapon range. We designed a study to examine the characteristics of rifle wounds, including both centerfire and rimfire rifles, especially pertaining to location and range of the wound. All deaths due to rifles examined at the Bexar County Medical Examiner's Office between 1988 and 2004 were reviewed. A total of 509 cases were identified, with 233 suicides and 266 homicides. We found that the average age of suicide victims (41.6 years) tended to be older than that of homicide victims (32.6 years). Suicides tended to be contact wounds to the head whereas homicides most often had multiple wound locations sustained from a distant range. The most common location to the head of suicidal wounds was intraoral whereas homicidal head wounds were more often to the temporoparietal region. We developed odds ratios for assessing the manner of death given a wound location or range; however, we caution that every case should be analyzed based upon it's unique circumstances and not solely its statistical probability.  相似文献

Fatal firearm accidents in Sweden   总被引:2,自引:0,他引:2  
According to Swedish law, it is prohibited to possess and use firearms without a special permission (license), which is given only after a detailed personal investigation. This restrictive legislation accounts for the fact that deaths due to firearms in Sweden are rare in an international comparison. The number of accidental firearm fatalities in Sweden is 0.074/100,000 living persons. We have previously published a series of accidental firearm fatalities during hunting, and now we present an investigation on the non-hunting fatalities. The mean age of the victims was 27 years, and males predominated. Handguns, military rifles, and shotguns caused most of the accidents. The first published case of fatal thoracic airgun wound is also included. Slightly more than half of the accidents were caused by another person and were inflicted at close range. Unsafe handling of the guns, especially "playing" with the gun or during military training caused most of the accidents. It is doubtful that one could further decrease the low number of fatal firearm accidents in Sweden by even more restrictive legislation. Instead, it is concluded that the most important factor to stress is the safer handling of weapons.  相似文献

Purpose. The main aim of the study was to examine the reasons and personality factors associated with confessions and denials. It was hypothesized that antisocial personality traits and active involvement in criminal behaviour would distinguish true confessors and true deniers from false confessors and false deniers. Method. The participants were 1,080 students in further education in Iceland. Each was asked about false admissions made to teachers and parents in the past, as well as about confessions or denials (true and false) made to the police during questioning, and the reasons for having responded in the way they did. The participants also completed questionnaires relating to offending, personality and self‐esteem. Results. One‐quarter (25%) of the participants stated that they had in the past been interrogated by the police in relation to a suspected offence, of whom 59% said they had confessed. A small minority of those interrogated (3.7%; 1% of the total sample) claimed to have made false confessions to the police, whereas 10% claimed to have made false confessions to teachers or parents. Males were significantly more likely to report false confessions than females. False confessions and false denials were significantly associated with antisocial personality traits, with Eysenck Personality Questionnaire Psychoticism being the single best predictor. Those participants who made true confessions and true denials were most normal in their personality. Conclusions. Personality is a significant predictor of who makes false confessions and false denials.  相似文献

The estimation of time since the latest discharge of rifles has been achieved by the SPME sampling technique and the GC-TEA analytical system. An unidentified compound, designated as the TEA2 compound, was detected in all the rifles investigated. The same compound was observed in shotguns and spent cartridges in our previous work. This compound escapes rapidly from the inside of rifle barrels, but can still be detected there one to two months after the shooting. The decrease of the TEA2 peak with time after shooting is non-exponential, and the curve-fitting procedure proposed for the estimation of time since discharge of shotguns can be applied also for rifles.  相似文献

How unrestricted or restricted should judges be when deciding a sentence? To what extent should sentences be predetermined, or to what extent should judges be left with the right to decide a sentence in each individual case? Some legal systems, most notably in the United States, have chosen sentencing guidelines to control judicial discretion. However, another approach has been to use computer technology in the form of so‐called sentencing information systems (SIS). This article examines these developments and what possible influence they have had and could have in the Scandinavian, particularly in the Norwegian, context. Penal institutions today are adjusting to the demands of the information society. Does and could the fact that we are living in an increasingly technologically mediated world influence judicial decision‐making? The article argues that the use of technology is not simply a question of technological change, but is first and foremost a social and political phenomenon, related to the relations of trust in a society.  相似文献

Purpose . The main aim of the study was to examine false confessions to police, parents and teachers and their relationship to personality and self‐reported offending. Method . The participants were 715 students in further education in Denmark. Each was asked about false admissions made to teachers and parents in the past, as well as about confessions or denials (true and false) made to the police during questioning. The participants completed questionnaires relating to offending and personality. Results . Seventy‐three (10%) of the participants said they had been interrogated by the police, of whom thirty‐seven (51%) said they had committed the offence. Five (7%) said they had given a false confession to police, whereas one hundred and seven (15%) of the total sample said they had given a false confession to parents or teachers. False confessions to teachers and parents were best predicted by the rate of self‐reported offending and high compliance. The single most commonly reported reason for making a false confession was to protect a friend. Conclusions . The findings in the present study corroborate many of those found in similar Icelandic studies, although there were some differences, including fewer people being interrogated in Denmark and a higher base‐rate of innocence of those interrogated. The study indicates that false confessions to police do happen on occasions which needs to be recognized by the authorities.  相似文献

Proper collection of glass evidence from crime spot is very important for its latter probative values. Glass evidence when properly collected and analyzed becomes a powerful witness and it can speak truth long after the crime. In criminal investigation glass evidence can tell what had happened and when it had happened. In the present study, a statistical regression analysis relationship between thickness of windowpane used as targets by soft nose bullet using.315"/8mm caliber sporting gun made in ordnance factory, India and various associated impact parameters were investigated. The relationship is found to be reasonably linear. The ballistics performance of windowpane has been found to correlate with the shear strength behavior above the elastic limit.  相似文献

Complications arise in the analysis of gunshot wounds to the maxillofacial region, when neither the projectile nor the gun is found at the crime scene. We simulated 5‐ and 15‐cm firing distances at a human mandible to investigate the external morphology of entrance wounds based on fire range. The ammunition models, .40‐caliber S&W, .380‐caliber, and 9 × 19‐mm Luger, were constructed with free‐form NURBS surfaces. In a dynamic simulation, projectiles were fired against mandibular body 3D model at 5 and 15 cm. All entrance wounds presented oval aspect. Maximum diameter and von Mises stress values were 16.5 mm and 50.8 MPa, both for .40‐caliber S&W fired at 5 cm. The maximum energy loss was 138.4 J for .40 S&W fired at 15 cm. In conclusion, the mandible was most affected by .40‐caliber S&W and morphological differences were observable in holes caused by different incoming projectile calibers fired at different distances.  相似文献

Police misconducts have very rarely been studied by the self‐report method because it is assumed that the ‘code of silence’ is too hard to break even in an anonymous survey research situation. In this study a self‐report method was carried out in a police unit in Finland. Respondents were shown a list of 16 possible conducts. They were asked whether they knew a police officer who had been engaged in misconduct mentioned in the list or whether they themselves had engaged in one or more of the misconducts mentioned in the list. The analysis results indicated that, in an anonymous self‐report survey context, police officers are clearly willing to report on service misconducts, both their own and those of their fellow officers. Thus, the assumed ‘code of silence’ does not seem as strong as the literature suggests.  相似文献

Purpose. When eyewitnesses to crime receive feedback about their choice of a suspect from a line‐up (or post‐identification feedback), such information can substantially alter their recollections of the witnessing experience. This study examined whether feedback exerts similar effects on investigators’ recollections of a suspect's behaviours. Methods. Participant‐investigators received training on speech cues that they were told, when present in a speaker's account, signal either honesty or deception. After hearing a suspect's account of a theft, participants decided whether the suspect was lying or telling the truth. One‐third of participants subsequently received immediate confirming feedback about their performance, while another third received disconfirming feedback. The remaining one‐third of participants did not receive feedback about their decision. Finally, participants rated the frequencies of speech cues that they had been instructed to detect in the suspect's account. Results. Disconfirming feedback significantly altered retrospective judgments about the characteristics of the suspect's account. Specifically, when told that the decision they made about the speaker's credibility was incorrect, participants judged the speaker as having exhibited fewer behaviours consistent with the credibility decision they had made, relative to those who either received no feedback or confirming feedback. Conclusions. Biases in recollections of a suspect may have consequences in real‐world interrogations wherein investigators assess credibility on the basis of numerous behavioural cues. Results are discussed in light of findings of post‐identification feedback studies on eyewitnesses.  相似文献

A bystander claimed to have been shot by a police officer, and CT scans were used to match qualitative and quantitative aspects of the unremoved bullet with police issued 9 mm Luger ammunition. CT scan methodology proved a valid approach for the measurement of bullets based on calculated measurement capability and correlation with “gold standard” physical measurement by vernier caliper. Measurements regarding length and base diameter, as well as length/diameter ratio, were insufficient to unambiguously identify a specific caliber, or a bullet of specific mass within a caliber class. It was, however, possible to exclude a bullet of specific design and mass with well‐characterized precision and accuracy values under selected CT scan conditions. A 9 mm Luger bullet (115 gr FMJ RN) was excluded from involvement in a shooting based on qualitative bullet shape combined with length, base, and ratio measurements of the bullet in‐situ for the victim.  相似文献

There is no lack of surveys showing that from a high rate of breastfeeding in the industrializing world of the early 20th century, after World War II the incidence declined to a nadir around 1960. For instance only a third of the infants in the US were given their own mothers' milk. The suckling of the new born is clearly not a natural instinct but needs to be taught and supported. Even if quantitative data is hard to come by for earlier centuries, there still is ample evidence that many mothers followed a tradition of not breastfeeding themselves, especially in the early 18th century. The reasons for this are partly economical, centered on the mother's heavy workload in non-industrial and energy-poor societies. But there are also cultural background factors behind the use of wet-nurses and artificial nourishment, where medical, religious and sexual ideas blend into a persuasive set of motives imprinting in women that breastfeeding is undesirable. The sending of urban babies to wet-nurses in the countryside was in part motivated by the tough epidemic climate in the cities. Modern anthropological research shows how cultural and economic motives can be doubly effective by reinforcing each other. The paper hypothesizes that for Western Europe where we have the richest historical records there may have been a breastfeeding pattern with more extensive breastfeeding in the northern parts of the continent and more use of wet-nurses and artificial nourishment in the Catholic southern parts, and that this may be rooted in long-lasting cultural factors. In addition there may have a number of places (Iceland, the Fennoscandian Arctic) where women had difficulty breastfeeding consistently because of an especially heavy workload in a tough environment, and where this developed into normative behaviour.  相似文献

Self‐embedding behavior (SEB) is the repeated insertion of sharp objects, such as needles or pins, into the soft tissues of abdomen, limbs, and other body parts. In this study, two cases of SEB were reported and the scientific worldwide literature reviewed. Thirty‐two cases of SEB were identified through systematic searches in the main bibliographic databases. Mean age was 35 years (SD = 8.97). Just over two‐thirds of the patients were female. Although the number of embedded objects could be as high as 200, major clinical and surgical complications were uncommon and mortality was null. Patients with SEB presented three major diagnoses: psychotic (25%), personality (21.9%), and factitious (28.1%) disorders. The practice of SEB largely went undetected as the patients themselves did not bring it to the attention of family members or physicians and usually denied they have engaged in SEB. A high level of suspicion is required to avoid a missed diagnosis.  相似文献

The entail was one of the few instruments that allowed pre-industrial testators to organize long-term strategies with respect to asset management: it allowed them to decide which goods descendants could alienate, and also after how many generations restrictions would be lifted. This article looks into the somewhat neglected topic of entailment in merchant towns, and thus contributes to our understanding of the goals urban testators set with respect to asset management, both for themselves and their descendants. Evidence from Amsterdam suggests that many testators were inclied to create long-term strategies once improvements had been made to the institutional framework surrounding the entail. Our analysis indicates that they were particularly looking for ways to prevent descendants from squandering patrimonial goods, but without reducing liquidity. This ‘intergenerational agency problem’ was solved by allowing groups of descendants to file requests to have entails cancelled.  相似文献
