The paraphilia-related disorders: an investigation of the relevance of the concept in sexual murderers

Paraphilic disorders (PAs) and sexual preoccupation are known risk factors for recidivism in sexual offenders. Nonparaphilic sexual excessive behaviors-so-called paraphilia-related disorders (PRDs), like paraphilias, are also characterized by sexual preoccupation and volitional impairment and can be diagnosed in paraphilic men. The prevalence and clinical significance of PRDs in sexual homicide perpetrators, however, is unknown. We investigated the relationship between PAs and PRDs retrospectively in a sample of 161 sexual murderers. Four groups were compared: men without a PA or a PRD diagnosis, men with at least one PRD but no PA, men with at least one PA but no PRD, and finally, those with a combination of both (PA+PRD). The PA+PRD group had the most lifetime cumulative sexual impulsivity disorders, more developmental problems, the highest persistent frequency of sexual activity, the highest number of previous sexual offences, more sexual sadism, and compulsive masturbation. Men of the PRD subsample had suffered more from childhood sexual abuse, showed more promiscuity, psychopathy, and alcohol problems. The use of the PRD concept in this special offender group should be further investigated with prospectively designed studies.     

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.     

An Empirical Analysis of 30 Years of U.S. Juvenile and Adult Sexual Homicide Offender Data: Race and Age Differences in the Victim–Offender Relationship

Abstract: Little is known about the racial patterns of crimes committed by sexual homicide offenders (SHOs). This study examined race and age influences on victim–offender relationship for juvenile and adult SHOs. A large sample (N = 3868) from the Supplemental Homicide Reports (1976–2005) was used. Analyses of victim–offender patterns included examining victim age effects (child, adolescent, adult, and elderly). The findings revealed several race‐ and age‐based differences. Black offenders were significantly overrepresented in the SHO population. This finding held for juveniles and adults independently. White SHOs were highly likely to kill within their race, “intra‐racially” (range 91–100%) across four victim age categories, whereas Black SHOs killed both intra‐racially (range 24–82%) and inter‐racially (18–76%), with the likelihood of their killing inter‐racially increasing as the age of the victim increased. This study underscores the importance of considering victim–offender racial patterns in sexual murder investigations, and it offers practical implications for offender profiling.     

Internet mediated crimes and theoretical approaches

Purpose: in the literature, the term ‘Internet crime’ has been coined to indicate the scenario in which a victim of homicide or other crimes is met through a chat room, and lured to death at the hands of the murderer. Various criticisms have been made of this new concept, on the grounds that the outcome is no different from that of other crimes committed without the use of Web resources, and so the method used has no particular influence. Indeed, it has been claimed that informatic crime just reflects a technological change in the nature of crime rather than a new form of criminal behavior attributable to the use of the Internet for criminal purposes. Method: our reflections were prompted by our experience as expert forensic psychiatry witnesses in three cases in which the aggressors had confessed to having had an exclusively virtual relationship with the victims, in which they spent a lot of time daily in a chat room. Conclusion: this scenario offers points for reflection on the nature of Web-mediated victim–aggressor interactions, to assess the effects on the planning and commission of the crime. Discussion. it’s our opinion that there really is such a thing as Internet-correlated crime, because in this case the quality and quantity of the Internet interactions progressively altered the men’s perception of the real relationship between themself and their victims.     

Extent, trends, and perpetrators of prostitution-related homicide in the United States

Prostitute women have the highest homicide victimization rate of any set of women ever studied. We analyzed nine diverse homicide data sets to examine the extent, trends, and perpetrators of prostitution-related homicide in the United States. Most data sources substantially under-ascertained prostitute homicides. As estimated from a conservative capture-recapture analysis, 2.7% of female homicide victims in the United States between 1982 and 2000 were prostitutes. Frequencies of recorded prostitute and client homicides increased substantially in the late 1980s and early 1990s; nearly all of the few observed pimp homicides occurred before the late 1980s. These trends may be linked to the rise of crack cocaine use. Prostitutes were killed primarily by clients, clients were killed mainly by prostitutes, and pimps were killed predominantly by pimps. Another conservative estimate suggests that serial killers accounted for 35% of prostitute homicides. Proactive surveillance of, and evidence collection from, clients and prostitutes might enhance the investigation of prostitution-related homicide.     

Compatibility Between Mental Disorder and Mental Capacity: Analysis of a Particular Case of Group Sexual Homicide

Abstract: On the night of August 19, 2000, at the foot of Castel del Monte, an 8‐year‐old girl was brutally murdered. The perpetrators were identified as five young men who captured their victim and sexually abused her. The policemen found the cadaver by following “Mario,” one of the five, who had been discovered lying on the ground, near the castle. Investigation led to demonstrate that the murder was not premeditated. The only desire of the group was to sexually molest the little girl. Mario showed signs of psychiatric pathology and for that he underwent psychiatric evaluation by judicial authorities. Analysis of this case, combined with a criminological and medical‐legal perspective led to conclusions very much different from the expectations of Mario’s defense attorneys. Mario, a marginal figure and seemingly the least intelligent, played the role of group instigator, both in the initiation of sexually abusing the child, as well as in the elimination of an inconvenient witness. However, the group was able to activate Mario’s sadistic fantasies and his sexual perversions, and he ended up in a catalyzing role influencing the behavior of others and realizing what would otherwise remain only fantasies. The circularity of the group allows people like Mario, who are apparently subordinate, to influence the behavior of others. Mario was found to have a mental disorder but it was not sufficient to diminish his personal responsibility related to the crime. In fact, according to Italian judicial code, it is necessary that the motivation for the crime was psychopathological. It was for this reason that, according to Italian law, all of the members of the group were considered to be responsible for the crimes committed and were condemned.

Fatal footsteps: murder of undocumented border crossers in Maricopa County, Arizona

In the past 5 years, the mortality rate among undocumented workers in Arizona has increased steadily. In 1998-1999, the number of deaths among border crossers was 28. That number increased dramatically in 1999-2000 to 106 and has exceeded 200 in each of the past 2 years. In the past, many immigrant deaths occurred as a result of dehydration and exposure (1). More recently, a new trend has emerged, that is, death of border crossers at the hands of the persons ("coyotes") hired to lead them across the border to safety. In some cases, the smugglers attempt to extort additional money from the families by holding the victims hostage once they have crossed the border into the United States. If the families fail to pay, the hostage is killed. Rival gangs are also murdering one another over their human cargo. Nine recent cases illustrate this trend in Maricopa County. In each example, the victims were bound, shot (or in one instance stabbed) and dumped in a remote desert area. All of the decedents were linked to murder for extortion by the 'coyotes' or rival gang members.

Firearm Deaths by Law Enforcement

Abstract:  The use of deadly force during law enforcement is a matter that compels public scrutiny. There were 42 gunshot deaths caused by police over a 4-year period in New York City. The decedents' average age was 31 years and ranged from 17 to 64 years. There were 41 males and one female; and 26 Black, nine Hispanic, and seven White decedents. Ethanol and/or drugs of abuse were detected in 78% (31/40) of the decedents. The vast majority of shootings occurred with the police responding to a crime and 90% of the decedents were armed (26 handguns, six knives, one axe, one metal pipe, and one toy gun). Vehicles were used as weapons in two incidents. A total of 177 bullets struck the 42 decedents. Fourteen decedents sustained single gunshot wounds (GSWs), and the remainder had multiple GSWs ranging from 2 to 21. In the majority of the cases in this study, the number of GSWs of the body was three or fewer. Thirteen decedents had at least one GSW of the back or buttocks, accounting for 25 of the total 177 wounds, and four of the 13 had GSWs of only the back. With the exception of the upper extremities, GSWs of all locations were more likely to penetrate than perforate. Although these deaths may be high profile, the certification is typically straightforward and the cause (i.e., GSW) and manner of death (homicide) are readily apparent. Although police shootings in which the decedent was unarmed and/or sustained numerous GSWs are widely reported by the lay press, these types of shootings were not typical in our study.     

Toxicology and Circumstances of Death of Homicide Victims in New South Wales, Australia 1996–2005

Abstract:  To determine the prevalence and circumstances of psychoactive substances amongst homicide victims, 485 consecutive cases autopsied at the NSW Department of Forensic Medicine (1/1/1996–12/31/2005) were analyzed. Substances were detected in 62.6% of cases, and illicit drugs in 32.8%. Alcohol, cannabis, opioids, and psychostimulants were most commonly detected. Alcohol and cannabis were both more prevalent amongst males. Mean ages were significantly younger for decedents who tested positive for a substance and for an illicit drug. Cases where death resulted from a physical altercation were more likely to have had alcohol and cannabis present. Illicit drugs were prominent amongst firearms deaths. The proportion of alcohol positive cases increased from 25.0% on Monday to 49.4% for Saturdays/Sundays. Alcohol was more common in incidents in the 0001–0600 h and 1800–2400 h periods. Psychoactive substances appear to substantially increase the risk of homicide, although there are important differences between drug classes in the circumstances of such incidents.
