Analysis of carboxyhemoglobin and cyanide in blood from victims of the Dupont Plaza Hotel fire in Puerto Rico

Ninety-seven people died from a fire that occurred in the Dupont Plaza Hotel in Puerto Rico on 31 Dec. 1986. All, except four who died later in the hospital, were found dead at the scene. All of the fatalities at the hotel (except for eight) were burned beyond recognition. Blood from seventy-eight of the victims was screened for carboxyhemoglobin at the Institute for Forensic Sciences in Puerto Rico and was then sent to the National Institute of Standards and Technology, Gaithersburg, Maryland, for analysis of carboxyhemoglobin and cyanide concentrations. The blood data indicated that carbon monoxide and hydrogen cyanide, singly or combined, were probably not responsible for the majority of the deaths that occurred in the badly burned victims. On the other hand, the significantly higher carboxyhemoglobin in the nonburned victims indicated that carbon monoxide alone or combined with hydrogen cyanide probably played a major role in the cause of their deaths.     

Methods for identification of 28 burn victims following a 1996 bus accident in Spain

A car collided head-on with a bus containing 56 passengers plus the driver. A few seconds after the crash, the bus caught fire and 28 persons (15 male and 13 female) lost their lives. All the deceased were almost completely incinerated. To establish the identity of the victims, the judge in charge of the case designated a multidisciplinary Identification Commission. Postmortem procedures included a general external examination, routine photographs, dental examination, dental (intraoral and extraoral) and general radiographs (chest, ankle, etc.), and complementary biological methods for identification (e.g., DNA analysis). The antemortem information, including dental and medical records available, were transcribed onto the INTERPOL disaster victim identification forms. The detailed ante- and postmortem information were compared manually. In this disaster dental identity could be established in 57% of the victims, whereas dental evidence did not allow by itself the identification of 12 burned victims. Odontological examination and complementary radiographic procedures were found to be accurate, economic and rapid methods of identifying badly burned victims in this bus accident.     

Victims' Rights, Victims' Expectations, and Law Enforcement Workers' Constraints in Cases of Murder

Research on crime victims and their experiences with the criminal justice system suggests that victims' rights (e.g., victim impact statements) and victims' services (e.g., crime victims' compensation, counseling) have not significantly improved victims' satisfaction with the criminal justice system or their recovery from the crime. Thus, we appear to know little about how to satisfy and assist victims of crime. This study uses the symbolic interactionist perspective to examine victims' experiences with law enforcement workers (e.g., detectives, counselors) with a focus on people who have lost a loved one to murder ("bereaved victims"). The data come from in-depth interviews with thirty-two bereaved victims, seven law enforcement workers, and three crime victims' advocates in Union County (pseudonym). Bereaved victims define the victim role differently from law enforcement workers, creating two main points of conflict with workers: (1) a conflict over their deceased loved one's body, and (2) a conflict over the flow of information in the case. Bereaved victims' frustrations over these conflicts created problems for their recovery. Bereaved victims' efforts to see their deceased loved one's body, guide detectives' investigation, and learn information about the murder and the investigation took a back seat to detectives' interests in protecting the integrity of the investigation and building a strong case for the prosecution. Policy implications are discussed.     

Investigation of cremations and severely burned bodies

Among the most difficult cases for law enforcement and medicolegal investigators to investigate are those in which victims have been deliberately burned to cover up a crime, or those in which cremation has resulted from an accident or suicide. This difficulty arises from the fact that the bodies may be destroyed or fragmented. The major objective in these investigations are twofold: The first task is to identify the body using every means available, including the aid of such experts as forensic pathologists, forensic anthropologists, dentists, toxicologists, and serologists as well as fire investigators, who can contribute to the investigation by providing information about the course of the fire.     

Forensic osteological investigations in Kosovo

A team of Finnish forensic experts performed investigations of alleged mass graves in Kosovo under the mandate of the European Union (EU). Human skeletal remains from two locations were examined. The remains contained three almost complete skeletons, and individual bones and bone fragments, part of which were burned. Injuries, pathological changes, and findings for identification purposes were examined and documented using standard methods of forensic pathology and osteology. Gunshot injuries were found in some cases, but reliable determination of the cause and manner of death was not possible. A discrepancy arose between the number of victims reported in information received from the presiding district court, and results of the investigations. The estimation of the minimum number of victims was mostly acquired by DNA analysis.

The rights of rape victims are enhanced: Using the law of premise liability for compensation

The field of victimology has been inundated with empirical evidence which demonstrates victims of crime have very few rights. Yet a new field of civil liability has been growing in the last few years which gives rape and assault victims a new avenue to be compensated for their injuries. This paper will demonstrate how the victims’ target is not the criminal justice system (through compensation from restitution or victim’s compensation statures). Nor is it the defendant (who usually makes no money). Rather, the target is the rich apartment complex owners and other owners of commercial premises who have failed to maintain their premises safely. As a result of their negligence, the victims fail to be afforded the right to visit or habitat or to sleep without fear and are ultimately raped. Jury verdicts in these premises liability cases have reached more than nine million dollars. This paper will analyze the legal process whereby one particular rape victim actualized her rights and gained significant monetary damages under this evolving law of premise liability. Finally, it proposes the creation of a new institutionalized program that promotes the rape victim’s rights to adequate compensation for her injury-the Rape Victims’ Rights and Opportunities Program.     

A New Tool for Coding and Interpreting Injuries in Fatal Airplane Crashes: The Crash Injury Pattern Assessment Tool Application to the Air France Flight AF447 Disaster (Rio de Janeiro–Paris), 1st of June 2009

For investigation of air disasters, crash reconstruction is obtained using data from flight recorders, physical evidence from the site, and injuries patterns of the victims. This article describes a new software, Crash Injury Pattern Assessment Tool (CIPAT), to code and analyze injuries. The coding system was derived from the Abbreviated Injury Score (AIS). Scores were created corresponding to the amount of energy required causing the trauma (ER), and the software was developed to compute summary variables related to the position (assigned seat) of victims. A dataset was built from the postmortem examination of 154/228 victims of the Air France disaster (June 2009), recovered from the Atlantic Ocean after a complex and difficult task at a depth of 12790 ft. The use of CIPAT allowed to precise cause and circumstances of deaths and confirmed major dynamics parameters of the crash event established by the French Civil Aviation Safety Investigation Authority.     

A homicide in the Ukraine: DNA-based identification of a boiled, skeletonized, and varnished human skull, and of bone fragments found in a fireplace.

In an apartment, bone fragments were found in a fireplace. Furthermore, a varnished skull was found elsewhere in the same apartment. The tenant confessed to a murder and stated that the head of a victim, a girl, was boiled for 12 hours. He stated that the soft tissue was then removed and the skull was varnished. Other parts of the body were burned to ashes in an open field. Comparison of loci D19S252, CD4, CYAR04, TII01, F13A01, F13B, and D6S366 from the skull and the bone remains to loci of the mother of a missing girl showed that the skull came from that missing child. Biological maternity was calculated as 99.99%. The bone pieces were DNA typed as male and did not share alleles with the mother in several systems. Therefore, they belonged to a different (human) victim.     

Factors influencing help-seeking behavior among battered Korean women in intimate relationships

In total, 123 battered Korean women who used domestic violence agencies were asked where they had turned for assistance in response to intimate partner violence. This study examined the factors related to use of formal and informal resources by these women. Formal resources included police, medical, legal, and shelter; informal were family or neighbors. Findings revealed that (a) the women studied used a variety of resources and that (b) income, violence-related injuries, and partner child abuse were related to whether they contacted police. Injury and partner child abuse were related to contacting a medical doctor/medical facility. Income, relationship status, and partner child abuse were related to approaching family or neighbors. The key finding was that partner child abuse increased the likelihood of battered Korean women seeking help from formal service resources and informal networks. This suggests the need for integrative services that link women's and children's protective services in order to meet the needs of both victims and children.     

Injuries due to deliberate violence in Chile

An analysis was made over a period of 6 months of the incidents involving deliberate violence as registered in 'Vicaria', the clinic for out-patients within the Cathedral of Santiago de Chile. A total of 236 victims of deliberate violence were observed. Men aged 15-24 years were found to be victims of deliberate violence most frequently. 'Under education' was the most frequently registered occupation for both sexes, and a large group of male victims were 'Unemployed'. 82% of the victims were men and 14% women, 1.5% were boys and 1.5% girls less than or equal to 14 years of age. None of the victims were alcohol intoxicated when arriving in the clinic. The incidents took place in streets for 81% of the male victims and 79% of the female victims, and in the majority of the cases the aggressor(s) was one (or several) police officer(s). Six percent of the female victims had been injured at home. There was no reporting of the aggressor being a relative or acquaintance. The most frequent type of violence was blunt violence from baton(s) (44%), while blunt violence without the use of instruments was reported less frequently (33%). The use of firearms was registered in 18% of the cases, and of sharp instruments, combustion, electro-shock and chain in 1.4%, 1.4%, 1.1% and 0.4% of the cases respectively. A total of 517 primary and secondary diagnoses were applied to the patients. Most of the victims (99%) had moderate or less serious lesions according to the Abbreviated Injury Scale (AIS) (score less than or equal to 2). Twenty-four percent of the victims had more than 4 lesions, and 7% more than 10 lesions. The head/neck region and the trunk were affected with equal frequency, the frequency of injuries of the head/neck region being comparable with that observed among torture victims and in contrast to the pronounced predominance of injuries of the head/neck region observed in a Danish emergency ward study of deliberate violence.     

Injuries due to deliberate violence in areas of Argentina. II. Lesions. Copenhagen Study Group

As part of a transcultural investigation of violent behavior in Argentina and Denmark, the lesions from accidents involving deliberate violence registered in the emergency wards of Hospital Fernandez and Hospital Pinero in Capital Federal Buenos Aires over a period of 13 and 17 months, respectively, were studied. Among the 281 victims entering the two emergency wards blunt violence without use of instruments was most often reported to be the violation method. Frequently indicated violation instruments against the male victims were batons (18.7%), sharp instruments (17.7%), and firearms (17.7%), the corresponding figures for female victims being 9.6%, 8.4% and 4.8%. The use of firearms and batons was considerably more pronounced in Argentina than in Denmark, particularly against male victims. A total of 373 primary and secondary diagnoses were reported from the patients, the most frequent diagnoses being contusions and open wounds in the head/neck region. Forty-three percent of the diagnoses were related to the head/neck region, being the most frequently injured region and the trunk the second most frequently injured region (30%). The degree of predominance of lesions in the head/neck region was much less than in the Danish material. Injuries of internal organs of the trunk were considerably more frequent in Argentina than in Denmark. Eighty-five percent of the victims had moderate or less serious lesions when assessed on the basis of the scores in the Abbreviated Injury Scale (AIS), (score less than or equal to 2). The AIS scores of the lesions in female victims were on average only slightly higher than those recorded in the Danish study, while 16.1% of the male Argentinian victims had lesions scored greater than or equal to 3 compared to 1.8% in male Danish victims. The need for treatment and hospitalization was more pronounced than in the Danish study. It may be concluded that the frequency of serious cases of deliberate violence probably would decrease if more restrictive rules for the possessing of firearms were enacted and enforced.     

The polymerase chain reaction and post-mortem forensic identity testing: application of amplified D1S80 and HLA-DQ alpha loci to the identification of fire victims.

The application of DNA typing methods after amplification by the polymerase chain reaction (PCR) of DNA derived from body tissues from charred fire victims was investigated. A total of 26 different tissue specimens from ten extensively burned individuals were analyzed. The samples included femoral muscle, psoas muscle, bone marrow and blood. The post-mortem period varied from 38 to 183 h. After amplifying the DNA by PCR from the various tissues, the D1S80 locus was analyzed with a high resolution polyacrylamide gel electrophoresis technique followed by silver staining and the alleles of the HLA-DQ alpha locus were detected by using a reverse dot blot format. All samples could be typed for both loci and the genotypes were consistent in the various tissues from each individual. A parentage test was performed in two cases and Mendelian inheritance of the alleles for both loci was observed.     

Comparative study of efficiency of dental methods for identification of burn victims in two bus accidents in Spain

This article deals with the usefulness and limitations of dental identification methods of human burn victims of two buses accidents in Spain. The first accident happened in Bailen in 1996 and involved 28 badly burned Spanish victims. In the second, in Illescas in 1997, 8 Japanese and 2 Spanish victims lost their lives. In both accidents, postmortem forensic procedures for identification were used, including external and internal examination, routine photographs, and dental examination. Dental identification was established in 57% of the cases in the Bailen accident and 80% in the Illescas accident. The success rate of dental identification varies considerably depending on the nature of the accident, the nationality and country of residence of the victims, the incidence of dental treatment, the availability of adequate dental records, and the degree of dental injuries. A discussion of procedures and methods for identification recommended when dealing with burn victims is included.     

Postmortem gastrointestinal ruptures in burn cadavers

The report informs on ruptures within the area of the gastro-intestinal tract of two siblings (2 and 3 years of age) that were fatally burned in their apartment. The ruptures are obviously pointing to an "explosive-like" evaporation of the watery part of the gastro-intestinal contents under the influence of the heat, at impeded pressure balance through shrinking of the esophagus caused by the heat in the upper area and the closure of the pylorus. Of significance here is surely also the shrinking of the gastro-intestinal wall caused by the heat and the thin abdominal walls which were not likely to have acted as "heat insulators". These findings are a supplement to the burn hematoma of the stomach as described by Berg and Schumann (1985).     

The challenge of identification following the tragedy of the Solar Temple (Cheiry/Salvan, Switzerland)

On October 5, 1994, 48 members of the Sect of the Solar Temple were found dead at two different locations in Switzerland: 23 victims in Cheiry and 25 victims in Salvan. Our Institute was commissioned to solve the forensic problems presented by this tragedy. Our goals were to establish the time of death, determine its causes, help elucidate the surrounding circumstances and identify the victims. This work presented us with the following challenges. This catastrophe was of an 'open' type: there was no list of 'passengers'; the victims were of five different nationalities and many had just arrived in Switzerland to participate in this event; family ties were very complex within this group; half of the victims were burned and sometimes charred; the exceptionally intense media converage of the story put a lot of pressure on the investigators and our Institute. In spite of these difficulties, all the victims were positively identified within 1 month. In the present report, we describe the steps realized to progress in our work. A special section describes our relationship with the journalists and their invaluable help in our investigations. The importance of being prepared for such an event is discussed.     

Four major disasters in Aquitaine,France: use of odontologic techniques for identification

The 4 mass disasters that have affected the Aquitaine region (France) in the previous 15 years are related through the specificity and the efficiency of dental methodology in identifying the victims. The results point to the decisive influence and the efficiency of dental methodology for identification of bodies that are burned or disfigured after an accident or a prolonged period in water.     

Sex-symmetric effects of coercive behaviors on mental health? Not exactly

The present study tested a section of the model of coercion in intimate partner violence (IPV) by investigating the relationships among coercion, IPV and mental health symptoms. The study's sample consisted of 573 culturally diverse university students (age M = 21.4) who completed a survey that measured past IPV victimization, coercive behaviors, and mental health symptoms. Structural equation modeling analyses revealed that coercion was a stronger predictor of adverse mental health symptoms than was IPV victimization. In addition, the study found that the adverse effect of coercive behaviors on mental health symptoms was stronger among female victims of IPV than among male IPV victims. The results have implications for theory building, future research, and mental health professionals who work with female and male victims of IPV.     

The violent female perpetrator and her victim

The aim of the present study was to examine the relationship between violent female offenders and their victims as well as the putative differences in the motives and specific psychological factors among three groups of female offenders: women who have victimised someone closely related to them, those who have victimised an acquaintance and lastly women who have victimised a stranger. More than half (N=61) of all violent female offenders hospitalised or incarcerated in Finland during the year of study were interviewed and assessed by Structured Clinical Interview II for DSM-IV (SCID-II) and Hare's Psychopathy Checklist-Revised (PCL-R). In 34% of the cases the victims were persons close to the offender, in 41% the victims were acquaintances and in 25% strangers. The victims in homicide offences were more often both male and closer to the perpetrator than in assault offences. Although motives were related to interpersonal problems, self-defence and long-term physical or psychological abuse were reported by only a few women, even for the small proportion of women whose victims were intimate partners. The most frequent reason for offences stemmed from confrontational situations in connection with alcohol use. Women who victimised acquaintances and strangers were also more likely to have a history of criminality and substance abuse than women who victimised those in close personal relationships. The latter were also more likely to have an antisocial personality disorder (PD) and psychopathic characteristics. There were, however, no significant differences found between those who had experienced physical or psychological abuse in childhood or adulthood and those who had no adverse experiences. These findings suggest that the violent behaviour by females leads more often to the death of the victim, when the victim is closely related to the perpetrator. The commonly-held view that violent female offending occurs primarily as a consequence of precipitation by the victim was not supported.
