Traumatic potential of colour marking cartridges (FX ammunition)

Colour marking cartridges as the FX ammunition (Simunition Europe, Brussels) are increasingly used by the police for realistic close range combat training. Conversion kits for service weapons of different manufacturers are available. The ballistic data of this ammunition is reported and experimentally verified. The risk of injury seems to be very low, if the recommended protective equipment is used. Small hematomas up to superficial lacerations are to be expected only in areas over a bony support. Shots to the unprotected eye will result in severe injuries.     

Homicide with postmortem opening of the thoracic and abdominal cavity--morphological, criminological and forensic-psychiatric aspects

During a walk a man found the partially unclothed body of a 16-year-old girl in a field near a village in South Baden. The body showed numerous injuries caused by sharp force. Several stab wounds were discernible on the neck, the chest, the genital region, the back and the right thigh. Postmortem, the anterior wall of the trunk had been severed with one long cut reaching from the mons pubis to the jugular fossa. The injuries and the scene suggested homicide with a sexual motive. Already on the next day a male suspect was ascertained. Blood traces of the victim could be demonstrated on his car. The man confessed the homicide, but did not describe the course of events in detail. He denied a sexual motive for the homicide. The psychiatric examination did not furnish any clues to internal, neurological or psychiatric disorders. The perpetrator did not claim intoxication for the time of the offence, which might have been relevant for the question of criminal responsibility. Psychodiagnostically, it was found that he had a narcissistic personality structure with a pronounced lack of self-esteem, deficits in affect processing and control as well as anxiety and aggression problems. The man was sentenced to life imprisonment for murder.     

Radiologically determined DMF index variations for forensic age estimation of young adults

The eruption and mineralization of third molars are the main criteria for dental age estimation of living people involved in criminal proceedings. Since the development of third molars is usually completed by the age of 19 or 20 years, this feature cannot be used to ascertain whether a person has attained the forensically relevant age of 21 years. This study examined whether the DMFT index or the third molar DFT index could supply reliable information enabling conclusions to be drawn about whether a person has reached the age of 21. To this end, 650 conventional orthopantomograms of German subjects aged 18 to 30 years were evaluated. The DMF index variations considered were found to be unsuitable for determining whether a person is over 21 because they displayed a weak correlation with age and considerable individual scatter. A high indicative value can only be attributed to a third molar DFT index of 4, although this is rarely observed in the relevant age group. An X-ray examination of the medial clavicular epiphyseal cartilage is, therefore, strongly recommended when assessing whether a person has attained 21 years of age.     

Y-STR polymorphism in Central Anatolian Region of Turkey

Eight Y-chromosome specific STR (Y-STR) loci including DYS19, DYS388, DYS389I, DYS389II, DYS390, DYS391, DYS392 and DYS393 were investigated in a group of males from Central Anatolian Region of Turkey. Healthy 59 males living in this region for at least three generations were included in the study. PCR analysis was carried out with Y-STR specific primers on genomic DNA obtained from peripheral blood samples and size determination of PCR products was performed by silver staining following 6% polyacrylamide gel electrophoresis (PAGE). DYS388 was found to be the locus with lowest diversity (D) whereas DYS389II was the locus with highest diversity. The current study presented a framework of variation for the eight Y-STR loci in Central Anatolian population.     

Differential pharmacological treatment of paraphilias and sex offenders

This article gives an overview of current pharmacological treatment of paraphilias and sex offenders focusing on the situation in Germany. Information about selective serotonin reuptake inhibitors (SSRI) is followed by data about established antihormonal substances (cyproterone acetate/CPA, and medroxyprogesterone acetate/MPA), as well as a more detailed account on luteinizing hormone-releasing hormone agonists (LHRH agonists). The results of open, uncontrolled clinical studies with SSRIs (n = 16) and LHRH agonists (n = 11) in paraphilic outpatients confirm the positive effects of these substances. A survey about the use of CPA and LHRH agonists in forensic hospitals in Germany shows that half of the patients treated with any kind of (anti-) hormonal agents received an LHRH agonist. The authors present a protocol on side effects, contraindications, and monitoring of CPA and LHRH agonists and develop an algorithm for differential pharmacotherapy of paraphilias.     

Munchausen syndrome by proxy (MSBP): an extreme form of child abuse with a special forensic challenge

Munchausen syndrome by proxy (MSBP) is a special form of child abuse in which an adult repeatedly produces symptoms of illness in a person under his/her care. In most cases the perpetrators are mothers who repeatedly and in different ways produce or feign symptoms of illness in their children in order to obtain medical treatment for them. MSBP is thus a special form of child abuse that is also of importance in the field of forensic medicine and a particular challenge to the medicolegal expert. We report two cases of poisoning with different substances (clozapine and clonidine) detected by toxicological investigations at our Department of Legal Medicine. The relevance of the problem for the medicolegal expert and the importance of an interdisciplinary co-operation are pointed out.     

Y chromosome STRs in Croatians

Eight Y chromosome short tandem repeat (STR) polymorphisms (DYS19, DYS388, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393) were analyzed in the sample of 457 unrelated Croatian men. A general STR allelic frequency pattern in Croatians corresponds to other European populations with the exception of the loci DYS19 and DYS389II. The most frequent DYS19 allele was 16, while at the DYS389II the most frequent were alleles 30 and 31. The most frequent Y chromosome haplotype (16-13-13-31-24-11-11-13) was found in 33 individuals (7.22%). One hundred and seventy-four haplotypes (38.07%) were observed in single copies.     

The identification of a dismembered human body: a multidisciplinary approach

A criminal case was directed to a multidisciplinary forensic team for identification, concerning a victim whose head, having two gunshot wounds, had been separated by a sharp instrument and was recovered 6 months later. The purpose of this research was to determine the sex and age of the victim for human identification. Primarily, macroscopic examination of the skull, tooth, and DNA analysis was conducted for sex determination. A rough assessment of age was made from the skull based on anthropological findings, however a more definitive result of age estimation was determined utilizing dental morphology. The dental data showed an age range of 32-37 from the mineral examination and the formulation of microscopic measurements. The results obtained from the skull and dental analysis matched with the physical characteristics of the victim's body, the known personal data of this person, and with the superposition of the photos gathered by a formal request. Besides, the result of DNA profiling of the victim showed male gender and direct relationship with the victim's presumed wife and daughter. Generally, research on human identification consists of sex and age determination. The sex characteristics can be precisely proved from DNA tests. However, age can be estimated by skeletal, and dental analysis. In this case the performed sex and age analysis lead the research to the selective matching of the missing person's identity.
