The authors discuss a variety of forensic matters using cases in which they have been involved as experts. Pertinent issues are illustrated in cases in which the offender is charged with homicide. The need for a comprehensive evaluation, the importance of corroboration of the offender's statements, and the value of preparing a thorough report are discussed.  相似文献

The distribution of Tf phenotypes in the population of Padua was investigated by ultrathin-layer isoelectric focusing. In our sample (n = 618) nine phenotypes, Tf C1, C2, C3, C3?1, C2?1, C3?2, C1B, C2B and C1D, were observed and the following frequencies calculated: TfC1 = 0.77837; TfC2 = 0.1804; TfC3 = 0.03641; TfB = 0.0040; TfD = 0.0008. These gene frequencies have been compared to those found in other populations. Analysis of 101 mother-child pairs was in agreement with an autosomal codominant mode of inheritance.  相似文献

A limited number of recent empirical studies suggest that inmates suffer from high rates of serious mental illness. Different explanations are offered depending on the type of institution: jail or prison. The literature is based largely on urban samples and does not offer comparisons of rates across types of institution within a single study. The present study examined a random sample of 213 jail and prison inmates in a rural state using the Diagnostic Interview Schedule (III-R). Among jail inmates there was little evidence of high rates of serious mental illness, suggesting the criminalization of mental illness may not be as evident in rural settings as urban areas. Among prison inmates, however, high rates of mental disorders were found, supporting previous findings in urban and rural jurisdictions. Implications of the findings are discussed in the context of a consolidated correctional system.  相似文献

Two hundred and twenty-eight consecutive medicolegal autopsies were studied as to the cause of death established by a physician, the mode of death as suggested in the police report, and findings of medical interest often discovered following autopsy. Corrections had to be made even in some cases which seemed to be obvious. With a decrease of the number of autopsies, the records of various registration bureaus would be affected. Autopsies are still necessary for control and correction of clinical causes of death.  相似文献

The volunteer movement in criminal justice settings is burgeoning. It has been estimated that by the end of 1982 there will be over one million volunteers working in criminal-justice-related functions. The volunteer role that appears to be increasing most rapidly is that of the one-to-one counseling relationship with delinquent and young adult offenders on formal or informal probation. While the demand for volunteer probation officers is increasing rapidly, few of our courts have attempted to develop and validate screening instruments capable of assessing and predicting the general competency of the volunteer. The need for such instruments has been emphasized recently by Judge Keith J. Leenhouts, Director of Volunteers in Probation, a division of the National Council on Crime and Delinquency. The present study attempts to assess the usefulness of one such potential screening device, the Critical Incident Response Test (CIRT) developed by Traitel (1972) and others at the Oakland County Juvenile Court in Pontiac, Michigan. It is hoped that this study will motivate other probation departments and court volunteer programs to develop and validate similar selection instruments.  相似文献
