In cases of acute fatal child abuse, certain injuries, including cutaneous blunt force trauma, skull fractures, subdural hematomas, intra-abdominal hemorrhage, and retinal hemorrhages are common and well described in the pediatric and forensic literature. These gross findings at autopsy, when taken into consideration with scene investigation and interviews with caregivers, may indicate both a clear manner and cause of death. In such cases, the discovery of additional pathologic changes attributable to older abusive injuries helps support a conclusion of death due to inflicted trauma. We discuss four cases of fatal child abuse in which acute blunt force abdominal trauma was the cause of death. In each of these cases, careful examination with proper sectioning and microscopy of select abdominal tissues revealed that the acute tissue trauma was superimposed on a background of older, healing injury. This older trauma was characterized by classic histologic elements of tissue repair, including fibroblast proliferation, early scar formation, increased vascularity, and hemosiderin-laden macrophages. Iron and trichrome stains were used to confirm the presence of hemosiderin and fibrosis in all four cases, but the recognition of fibroblast proliferation and a reactive vascular pattern was best seen on routine hematoxylin and eosin stains. The gross and microscopic autopsy findings, along with available investigative information, established the diagnosis of chronic physical abuse. 相似文献

Suicide by cop has become a familiar topic among members of law enforcement, mental health professionals, and the general public. This paper presents two cases where police officers chose to commit suicide by getting other police officers to kill them. The two police officers studied, by examination of closed case files, were found to be similar to civilians who committed suicide by cop on several demographic (gender, age, history of mental illness, and suicide attempts), and situational (stress factors, trigger) variables. The cases help us to understand possible motives and management for individuals who choose to end their life in this manner. 相似文献

Although sexual homicide is receiving increasing research attention, few studies have examined the criminal histories of sexual killers in any detail. This study examined the criminal histories of 81 British stranger sexual killers to determine whether they were generalist, specialists or both and whether their criminal histories reflected violent, sexual, marginality and over control pathways. Results found most stranger sexual killers were generalist offenders and sexual homicide was part of a varied criminal repertoire and non-sexual crimes predominate. This ‘antisocial orientation’ means future offending may not be limited to sexual violence. Criminal histories reflected the violent, sexual, marginality and over control pathways, but offenders in the violent pathway were more criminally orientated. The clinical and investigative implications of these findings were considered as they suggest knowledge of the criminal histories of stranger sexual killers is an important consideration for criminal justice professionals. 相似文献

Texas's approach to juvenile capital offenders has been profoundly lacking any balance of the interests of accountability and rehabilitation. Texas has employed adult transfer for juvenile capital offenders with potential life imprisonment and possible parole in 40 years and determinate sentencing to adjudicate capital offenders in juvenile court, yielding a maximum sentence of 40 years in prison. Legislative initiatives in the 1990s to curtail parole have led to only 22 percent of violent offenders receiving early release while serving an average of 61 percent of their sentence. Aggravated offenders, including youth capital offenders, serve at least 80 percent of their total incarceration time. Notably the Texas framework does not effectively allow for offenders whose acts were the product of either an undeveloped or disabled mental capability to be punished appropriately and distinctly from those who possess psychotic or antisocial tendencies—or adult offenders. This deficiency is worsened as a result of the recently passed legislation SB.60, which establishes that juvenile capital offenders must receive the sentence of life without the possibility of parole upon conviction. Texas can create a more precise approach with three modifications: (1) centralize all youth capital adjudications to a criminal court, (2) effectuate separate imprisonment and enhanced educational programs for the first ten years of incarceration, (3) implement a “soft-ten” sentence where after the initial ten years of imprisonment the presumption for release favors the offender unless the state establishes that additional time is needed; this determination is primarily based on a complete psychological assessment of the offender. 相似文献

有些人误认为公安部提出“命案必破”就是强调破案率,就是承诺100%的破案,就是宁可错究也不可错放,结果急功近利、造成冤假错案,从而对“命案必破”提出了质疑和否定。究其原因,主要是对“命案必破”理解把握不准所致,只有正确把握和应用好“命案必破”这把“双刃剑”,才能发挥和挖掘其应有的最大价值。 相似文献

With data from the 1979–1985 Longitudinal Mortality Study, we examine the effects of marital status and social isolation on adult male homicide (ICD-9 Codes E960-E978). Cox proportional hazards models were fitted to a 1979–1981 population cohort of approximately 200,000 adult men and their mortality experiences were followed until 1984–1985. Multivariate hazards regression analysis showed that marital status and social isolation are associated with significantly higher risks of homicide victimization. Controlling for age and other socioeconomic covariates, single persons were 1.9 times, and divorced, separated or widowed persons were 1.7 times, more likely to die from homicide than married persons. Socially isolated persons were 1.6 times more likely to become homicide victims. Other adult males with increased risk of homicide victimization were African Americans and those who lived in the inner city. 相似文献

To understand the mortality patterns among drug users and potential risk factors, we evaluated drug‐related deaths reported to the Florida Medical Examiners Commission from 2001 to 2013, by substances, demographics, and manner of death. The annual drug‐related fatalities increased by 57% from 2001 to 2013 (total n = 100,882); 51.8% were accidental, 7.9% homicide, 18.6% natural, and 19.6% suicide. The different manners of death exhibited distinct demographic profiles and drug composition. The gender gap was more prominent in homicide. Age ≥55 years was more closely associated with natural death and suicide. Age <35 years and central nervous system (CNS) stimulants including amphetamines and cocaine showed higher relative risks for accidental death and homicide, whereas CNS depressants including benzodiazepines, carisoprodol, opioids, and zolpidem were more strongly associated with accidental death and/or suicide. The findings aid in identifying populations more vulnerable to drug‐related deaths, developing targeted interventions and thereby improving efficiency of preventive efforts. 相似文献

Biased decision-making in criminal investigations can impede or arrest the progress of justice. Previous research has not systematically addressed the effects of professional experience on the quality of detectives’ decision-making. Using a quasi-experimental design, this study compared the quality of investigative decisions made by experienced detectives and novice police officers in two countries with markedly different models for the development of investigative expertise (England and Norway). Participants (N?=?124) were presented with two semi-fictitious cases and were asked to report all relevant investigative hypotheses and necessary investigative actions in each case. The quality of participants’ responses was gauged against a gold standard established by a panel of senior homicide experts. In the English sample, experienced detectives vastly outperformed novice police officers in the number of reported gold-standard investigative hypotheses and actions. In the Norwegian sample, however, experienced detectives did not perform any better than novices. We argue that English (vs. Norwegian) detectives may benefit more from professional experience due to their Professionalising Investigation Programme and a nationwide accreditation program, requiring them to engage in extensive standardized training, systematic evaluation and synchronized development. In contrast, Norway lacks such requirements. Methodological limitations and implications for police training and accreditation policies are discussed. 相似文献
