Lethal child abuse (through the use of physical force) in the German Democratic Republic during the period 1 January 1985 to 2 October 1990. Results of a multicenter study

No reliable data are available on cases of lethal child abuse (by active force) in the area of the former German Democratic Republic. In a multicenter study we therefore examined the police and court records for such cases occurring in the period 1 January 1985 to 2 October 1990 in the entire area of the former German Democratic Republic. RESULTS: The study center received information on 39 cases of lethal child abuse which correspond to approximately 7 cases per year. However, a low percentage of undetected crimes which cannot be determined more precisely has to be taken into consideration. Almost 40% of the victims were younger than 1 year, 73% of the victims showed indications of repeated ill-treatment. The effects caused by using direct blunt forces, against the head in particular, were by far the most frequent causes of death. The male contact person (the victim's father, brother or stepfather as well as the life companion of the child's mother in particular) killed the child in most of the cases. As far as it is known, 37% of the male/female offenders suffered from chronic alcoholism; 32% of the male/female offenders were under the influence of alcohol when the crime happened. 83% of the male/female offenders who were found guilty made a confession shortly after the crime had happened or during the interrogations. Almost all the male/female offenders were sentenced to prison (the duration of the imprisonment varied between one year and for life). Due to the considerably lower section rate compared to the one in the German Democratic Republic, it is to fear that each second fatal child abuse is not detected in the new federal states.     

Practice of forensic entomology. Part 1: Insect collection at the site of discovery of the corpse

The life cycle of a fly illustrates that the late immature stages of necrophagous insects frequently leave the body, and are therefore not found on the corpse itself. Taking into account these stages (i.e. pupae) while investigating a death scene is very important. Two case histories demonstrate the effects of not taking that fact into consideration when determining the post-mortem interval. Since there is no standardized method in Germany for collecting insects at a death scene, an entomological collection kit with a short instruction is introduced.     

Fatal child abuse (caused by physical violence) in Germany during 1 January 1985 to 2 October 1990. Results of a multicenter study]

No reliable data are available on cases of lethal child abuse (by active force) in the area of Federal Republic of Germany prior to reunification (the former West Germany). In a multicenter study we therefore examined the police and court records for such cases occurring in the period 1 January 1985 to 2 October 1990 in nearly the entire area of Federal Republic of Germany. RESULTS: The study center received information on 58 cases of lethal child abuse. Extrapolated to all institutes of legal medicine, this corresponds to 62 cases in all of West Germany in the period studied. An approximately equal number of unreported cases should be added to this figure. Including unreported cases, at least 20 cases of lethal child abuse occurred per year; thus only one in every two cases ever came to light. Almost two thirds of the victims were younger than one year old. At autopsy 59% exhibited signs of repeated abuse at autopsy. By far the most common cause of death was direct impact from a blunt object, usually to the head. Mostly, the male person to whom the victim relates most closely (father, stepfather, partner of the mother) has killed the child. Twenty-one of the 74 persons charged saw the charges against them dropped or were acquitted due to lack of evidence; 51 received sentences ranging from one year probation to life. In the remaining two cases the outcome of the trial was unknown. Signs of abuse were readily apparent at autopsy in almost all cases. The high number of unreported cases underscores the need to educate medical students and practicing physicians to be on the look-out for signs of abuse and argues for an increase in the rate of autopsy.     

RECONSIDERING THE RELATIONSHIP BETWEEN SES AND DELINQUENCY: CAUSATION BUT NOT CORRELATION*

Many theories of crime have linked low levels of socioeconomic status (SES) to high levels of delinquency. However, empirical studies have consistently found weak or nonexistent correlations between individuals' SES and their self-reported delinquent behavior. Drawing upon recent theoretical innovations (Hagan et al., 1985; Jensen, 1993; Tittle, 1995), we propose that this apparent contradiction between theory and data may be reconciled by recognizing that SES has both a negative and a positive indirect effect upon delinquency that, in tandem, results in little overall correlation between the two. We tested this proposal with longitudinal data from the Dunedin Multidisciplinary Health and Development Study. We used measures of parental SES recorded at study members' birth through age 15, social-psychological characteristics at age 18, and self-reported delinquency at ages 18 and 21. We found that low SES promoted delinquency by increasing individuals' alienation, financial strain, and aggression and by decreasing educational and occupational aspirations, whereas high SES promoted individuals' delinquency by increasing risk taking and social power and by decreasing conventional values. These findings suggest a reconciliation between theory and data, and they underscore the conceptual importance of elucidating the full range of causal linkages between SES and delinquency.     

Iliac cancellous bone in drug addicts: a histomorphometric study

Histomorphometry was used to determine structural bone changes in drug addicts. Iliac crest bone biopsies were obtained at autopsy from 28 subjects (21 male, 7 female, aged 18 to 45 years) who had a history of drug abuse and had died due to overdose of illicit drugs. For histomorphometry, undecalcified sections were investigated using the Merz grid. The following histomorphometric indices were measured and calculated: BV/TV, BS/BV, Tb.Th, Tb.N, Tb.Sp, OV/TV, OS/BS, Ob.S/BS, O.Th, ES/BS, Oc.S/BS, and N.Oc/T.A. In 28 controls (24 male, 4 female, aged 17 to 47 years) trabecular bone specimens were investigated in the same way. The parameters in drug addicts did not show any correlation to age, body weight, height or sex differences. Trabecular bone volume and trabecular thickness were slightly but not significantly increased (BV/TV: 23.37 +/- 5.77% (mean, SD), controls 22.23 +/- 5.08%, p = 0.434; Tb.Th: 172.67 +/- 36.83 mcm, controls 169.73 +/- 36.13 mcm, p = 0.764). Only the eroded surface was significantly different to the controls (ES/BS: 8.16 +/- 2.04%, controls 6.96 +/- 2.17%, p = 0.038). We conclude that the incidence of metabolic bone disease in drug addicts is low.     

Population data on the thirteen CODIS core short tandem repeat loci in African Americans, U.S. Caucasians, Hispanics, Bahamians, Jamaicans, and Trinidadians

Allele distributions for 13 tetrameric short tandem repeat (STR) loci, CSF1PO, FGA, TH01, TPOX, VWA, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, and D21S11, were determined in African American, United States Caucasian, Hispanic, Bahamian, Jamaican, and Trinidadian sample populations. There was little evidence for departures from Hardy-Weinberg expectations (HWE) in any of the populations. Based on the exact test, the loci that departed significantly from HWE are: D21S11 (p = 0.010, Bahamians); CSF1PO (p = 0.014, Trinidadians); TPOX (p = 0.011, Jamaicans and p = 0.035, U.S. Caucasians); and D16S539 (p = 0.043, Bahamians). After employing the Bonferroni correction for the number of loci analyzed (i.e., 13 loci per database), these observations are not likely to be significant. There is little evidence for association of alleles between the loci in these databases. The allelic frequency data are similar to other comparable data within the same major population group.     

A validation study for the extraction and analysis of DNA from human nail material and its application to forensic casework.

A validation study was conducted to demonstrate that deoxyribonucleic acid (DNA) could be successfully extracted from human nail material and analyzed using short tandem repeat (STR) profiling and/or mitochondrial DNA (mtDNA) sequencing. This study involved the development of a DNA extraction protocol that includes a cleaning procedure designed to remove external contaminants (e.g., biological, chemical). This protocol was used to test human nail material that had been soaked in whole blood from a second donor and coated with gold-palladium to simulate scanning electron microscopic analysis. The results showed no indication of a mixture and were consistent with that of the nail donor. Fresh human nail material usually yielded both STR profiles and mtDNA sequence information; however, aged human nail material (approximately eight years old) yielded only mtDNA sequence information. Upon completion of the validation study, the extraction protocol was used for the analysis of a torn fingernail fragment recovered from the scene of a violent homicide in 1983. A partial STR profile and mtDNA sequence information indicated that the fingernail fragment was excluded as originating from the suspect and was, in fact, consistent with originating from one of the victims.     

Evaluation of prostate-specific antigen (PSA) membrane test assays for the forensic identification of seminal fluid.

Prostate specific antigen (PSA, also known as p30), a glycoprotein produced by the prostatic gland and secreted into seminal plasma, is a marker used for demonstrating the presence of seminal fluid. Methods for the detection of PSA include Ouchterlony double diffusion, crossover electrophoresis, rocket immuno-electrophoresis, radial immunodiffusion, and ELISA. The extremely sensitive ELISA technique can detect PSA in concentrations as low as approximately 4 ng/mL. However, all these techniques are cumbersome and time consuming to perform in forensic laboratories, especially when only a few samples per week are processed. Various membrane tests are currently used in clinical settings to screen a patient's serum for the presence of PSA at levels greater than 4 ng/mL. In this study we evaluated three immunochromatographic PSA membrane tests by analyzing semen stains stored at room temperature for up to 30 years, post-coital vaginal swabs taken at different time after intercourse, semen-free vaginal swabs, and various female and male body fluids, including urine. The data demonstrate that PSA membrane test assays offer the same sensitivity as ELISA-based tests and provide a rapid approach for the forensic identification of seminal fluid. Furthermore, when the supernatant from a DNA extraction is used for the assay, there is essentially no DNA consumption for determining the presence of PSA in a forensic sample.     

Recovering the Indigenous Legal Traditions of India: Classical Hindu Law in Practice in Late Medieval Kerala

The collection of Malayalam records entitled Vanjeri Grandhavari, taken from the archives of an important Namputiri Brahmin family and the temple under its leadership, provides some long-awaited information regarding a wide range of legal activities in late medieval Kerala. The organization of law and the jurisprudence represented by these records bear an unmistakable similarity to legal ideas found in dharmastra texts. A thorough comparison of the records and relevant dharma texts shows that landholding Namputiri Brahmins, who possessed enormous political and economic power in the region, mediated the implementation of dharmastra into the legal system. From this comparison arise new understandings of law and legal categories such as custom and positive law. Moreover, such comparisons begin to elucidate the problems involved in Western assumptions that it is textual law, not its interpretation and application by humans, which controls behavior. The Vanjeri records demonstrate not only the importance of dharmastra as a historical document but also the manner and extent to which dharmastra provided the foundation for legal systems in Kerala as well as in other regions of India.
