Frequency of serial sexual homicide victimization in Virginia for a ten-year period

The frequency of serial sexual murder has been widely discussed, and estimates of the number of victims in the United States range from 500 to 6000 per year. This study attempted to quantify the number of serial sexual murder victims in Virginia for a ten-year period. Multiple sources of data were utilized, including Federal Bureau of Investigation (FBI) case files, FBI's Violent Criminal Apprehension Program (ViCAP) reports, Virginia State Police ViCAP reports, Virginia Homicide Investigators Association, and the Virginia Division of Forensic Science DNA database, to effectively cull out all the known serial sexual murder victims for the given time period. Review of these records revealed a total of 28 victims of serial sexual murder, compared with a total of 5183 murder victims for the same ten-year period. The frequency of serial sexual victimization was 0.5% of all homicides for the given period. These results highlight the unusual frequency of serial sexual murder.     

Loneliness and associated violent antisocial behavior: analysis of the case reports of Jeffrey Dahmer and Dennis Nilsen

It can be theorized that loneliness plays a significant role in the development and continuation of violent, antisocial attitudes and behavior. Analysis of case reports of two serial killers, Dennis Nilsen and Jeffrey Dahmer, indicate that there is evidence for such a link. In this article, a list of significant correlates of loneliness and antisocial behavior is presented. This may be useful for the assessment of possible dangerousness and in the development of prevention and intervention programs. Suggestions are made for the adequate treatment of loneliness and correlated violent, antisocial behavior. A need is recognized for more research into the psychosocial, emotional, neurobiological, cultural, and ethnic determinants of loneliness and their correlation to specific antisocial and/or criminal behavior.     

Spousal homicide and the subsequent staging of a sexual homicide at a distant location

The case of a 63-year-old man who killed his 52-year-old wife and then staged a sexual homicide at a distant location is reported. A review of all evidence, a forensic psychological interview, and psychological testing indicated that the murder was the result of a narcissistic rage reaction during which the subject beat his wife to death with a paint can, a clothing iron, and a rock. He then drove her body to a field 87.3 miles away, and positioned it in a manner that exposed her breasts and her underwear. He turned himself into the police two days later. There is no controlled empirical research on staging, although this single case supports the criminal investigative theory that staging exists, and is done to deliberately mislead homicide investigations (Douglas et al., 1992).     

A case of stalking in the workplace and subsequent sexual homicide

A case of stalking in the workplace and subsequent sexual homicide by a 33-year-old male is reported. Following several months of stalking a 38-year-old female, the male subject went to the woman's office after business hours and restrained, raped, and murdered her. The cause of death was multiple stab wounds. The facts of the case reveal that the subject fits a predatory-type stalker, which represents a small subgroup within stalkers that has received little attention. Unlike other types of stalkers, the predatory stalker gives little warning to their victim (or multiple victims), as their stalking behaviors tend not to be very invasive or harassing. In general, most stalkers are not physically violent; however, predatory-type stalkers, given their tendency for sexual violence, are dangerous and the importance of identifying them is emphasized. Factors associated with perpetrators of sexual homicide are discussed.     

The future of homicide offenders. Results from a homicide project in Copenhagen

As a part of a Copenhagen homicide project, 52 released homicide offenders were followed during a mean period of 9 years. Pessimistic expectations were confirmed as post-release rates of criminality, psychiatric admission, and suicide were all very high. By logistic regression analyses, young age by release, and long stay in prison were found to increase the risk of further criminality, and previous psychiatric admission was found predictive of future admission. The problems in using logistic regression analysis on variables--all of whom may be viewed as "parallel" indicators of a common tendency to adverse behaviors--are discussed. In conclusion, the results have been used for a tentative division of homicide according to the offender-victim relationship into intra-family homicide and extra-family homicide. In intra-family homicide the most important dimension seems to be the psychic state of the offender, in extra-family homicide more impact should be attributed to the social dimension.     

Aggression homicide and rejection homicide: a communicative classification of homicide

Based on a 10-year sample of homicides (n = 50), the hypothesis was tested that it is possible to differentiate between aggression and rejection homicide. The aggression homicide results from the offender/victim relationship, which is no longer accepted for some reason. In contrast, in the rejection homicide the offender radically strives for a goal which can only be reached if the victim is eliminated. Based on forensic-psychiatric expert opinions (n = 50), the case analyses yielded 31 aggression homicides and 18 rejection homicides, one case could not be classified. Aggression homicides differed significantly from the rejection homicides with regard to their main motives. Hate in quarrel (n = 8), violent occupation of the victim (n = 7), delusions (n = 5), revenge (n = 3), self-defence (n = 2), and jealousy (n = 1) characterized the aggression homicides, whereas rejection homicides were dominated by economic motives (n = 14). Two offenders intended to get rid of the victim and one offender wanted to rescue a third person. From a forensic-psychiatric point of view, the pertinent statistical data (social data, diagnosis, criminal responsibility) are reported and the significance of the differentiation between aggression homicide and rejection homicide for medico-legal or criminological case profiling and for the prognosis of the risk potential is discussed.     

The social ecology of homicide: A modified lifestyle/routine activities perspective

Recent research on criminal victimization suggests that lifestyle may offer important insights into the unequal distribution of crime. The lifestyle approach is used here to explore variations in homicide rates for Dade County, Florida. The application of this approach to the analysis of cross-sectional variations in homicide rates requires (1) elaboration of the assumptions that connect the likelihood of victimization for individuals to variations in the rate of victimization by location as well as (2) justification of the selection of specific variables as indicators of variation in exposure to the risk of homicide. In sum, four individual characteristics and six residential characteristics are said to be implicated in the explanation of variations in homicide rates among census tracts. Census tract data derived from 1980 Bureau of Census files are used to explore these variations. Findings suggest that future researchers should consider the relative importance of individual attributes, especially marital status, in increasing the risk of homicide victimization.     

Stalking,homicide, and catathymic process: a case study

Despite the proliferation of research on various aspects of stalking, there has been relatively little study of stalkers who commit homicide. In this article, a man who stalked and killed a casual acquaintance is reported. He developed an idea to kill her that, at first, seemed ego-alien and unreal but eventually became fixed and was accompanied by a mounting inner pressure to act. The concept of catathymic process--a change in thinking whereby the offender comes to believe that he can resolve his inner conflict by committing an act of extreme violence against someone to whom he feels emotionally bonded--is of particular help in understanding this case, as well as similar cases of stalking that culminate in homicide.     

Child sexual abuse: an Italian perspective

The problem of child sexual abuse is a growing reality in Italy. The experience of over 200 children seen by the SVS (Soccorso Violenza Sessuale) Centre in Milan (the first Italian large-scale study) may give more information on the European situation. This study is a retrospective study based on information contained in the files of children beneath the age of 14 seen at the SVS Centre between May 1996 and May 2003, who arrived with a suspicion of child sexual abuse. Over 80% of all cases fell within the normal-aspecific category according to Adams' 2001 classification. This first Italian survey, though not based on substantiated cases but only on cases of suspected sexual abuse, supplies a perspective on a large northern European city such as Milan. Data seem similar to those published in other non-European studies, particularly as regards clinical signs observed. Thus, the results of this study, with all their limitations, start to give a perspective on the frequency and type of child population reaching this Italian center, what the scenarios are, what signs the children present and how infrequent it is to find clinical anogenital signs concerning for sexual abuse.

The case for regulating collaborative reproduction: a children's rights perspective

There is little regulation of collaborative reproduction--the use of the eggs, sperm, or embryos of a third party to create a child biologically unrelated to at least one intending parent. This Article argues that the dearth of regulation should be assessed from a children's rights perspective and accordingly adjusted. After examining the effects of the experimental reproductive technologies, it concludes that traditional family law preferences and policies are undercut by the deliberate creation of collaboratively reproduced children. The lack of regulation might stem from constitutional protection afforded parents in the right of privacy and substantive due process cases. The author, however, contends that collaborative reproduction implicates the rights of children and requires a separate balancing of rights not contemplated in other cases. Collaborative reproduction also requires regulation because of its spill over effects on the acceptability of cloning. The Article concludes by offering several possible regulatory responses to the problems posed by collaborative reproduction.     

Identification of serial homicide victims in the "Green River Murder" investigation

The Green River Murder Investigation in King County, Washington, is currently the longest and most active serial murder investigation in U.S. history. To date, little information has been reported on methods used in identification of serial murder victims. In this paper, various methods used in victim identification are reviewed and difficulties encountered during the course of the investigation are described. The experience of the authors is presented in order to acquaint other agencies with problems of victim identification associated with these serial murder victims and to provide key methods that may be useful in other such investigations.     

Luis Alfredo Garavito Cubillos: criminal and legal aspects of serial homicide with over 200 victims

This is the first scientific report on the crimes of the homosexual paedophile sadist Luis Alfredo Garavito Cubillos, based on a research stay of the authors in Columbia, and including discussions with the investigators, and the offender. Between 1992 and 1999, Garavito killed more than 200 children in the core age span between 8 and 13 years (as an exception, 6 to 16 years). His modus operandi remained stable. During daytime, he lured children of a lower social status out of crowded parts of the city into hidden areas that were overgrown with high plants. Garavito promised either payment for easy work, or drugs, or made other socially believable offers. The children were tied up, tortured, raped, and killed by at least one cut in the lateral part of the neck, or by decapitation. During the killings, Garavito was drunk. Even after his arrest (for attempted sexual abuse under a wrong identity) it was not immediately possible to track his crimes since Garavito had frequently changed his places of stay and his jobs. He also grew different hairdos and used wrong names. During his still ongoing confessions, he directs the investigators correctly to all scenes of crime spread over large parts of Columbia. In our report, we give an overview over the course of investigations, hint to similarities in the cases of the German serial killer Denke (1920's) and homosexual paedophile serial killer Jürgen Bartsch (1960's), and give preliminary impressions on the offender's personality. Furthermore, the violent environment and juridical peculiarities in Columbia are discussed. In spite of a total penalty of 2600 years in prison, it is formally well possible that Garavito will be released out of prison within the next 10 to 20 years, i.e. even before the maximum sentence of 40 years will be over.     

Caddisflies assist with homicide case: determining a postmortem submersion interval using aquatic insects

Although few indicators of time since death for corpses found in aquatic ecosystems are comparable in precision to the insect indicators used in terrestrial cases, there are observations that can be useful in suggesting or ruling out an approximate PMSI (postmortem submersion interval). For example, the time intervals required for certain growth phases of aquatic insects, such as caddisflies, that may attach themselves to the submerged remains can be used to estimate a minimum PMSI. Approximately 8 of the 13 orders of insects containing species with aquatic or semi-aquatic stages are likely to be associated with carrion or corpses in aquatic habitats. We present a case study in which portions of a body from an adult male were discovered in a south central Michigan stream. The body was dismembered and portions were recovered from two bags floating and submerged in the stream. Insect specimens collected from mesh and plastic bags consisted of one fly larva belonging to the family Muscidae, and caddisfly larvae belonging to two families: the Limnephilidae. (case-makers) and the Hydropsychidae, (net spinners). We used unique case-building behaviors of the limnephilid caddisflies found on the remains to elucidate a PMSI range consistent with the disappearance of the victim. It is important for forensic investigators to understand that although some precision is lost in estimating a PMSI with aquatic insects, these organisms should not be ignored in gathering evidence from aquatic crime scenes, and in fact, they can provide valuable details in estimating a PMSI.     

Cyanide fatalities: case studies of four suicides and one homicide

Deaths due to cyanide poisoning are relatively rare, largely owing to the restricted availability of cyanide. Nevertheless, the authors report five cases of cyanide fatalities occurring within a few months. Cyanide is one of the most rapidly acting poisons known and is still used for suicide and homicide. The discussion focuses on the circumstances, metabolic changes, pathophysiology, blood levels, diagnosis, and management of cyanide poisoning.
