The Origin of the Multidisciplinary Collaborative on Sexual Crime and Violence

In August of 2010, I began recruiting for the 'Serial Homicide Expertise and Information Sharing Collaborative‏' (SHEISC), an initiative with the expressed goal of creating an online serial homicide database. The collaborative brought together serial homicide researchers from around the world, each contributing their own painstakingly compiled data to one central database. Collaboration such as this had never been conceived up to that point since serial homicide researchers typically worked in silos, sharing information only with their own team. 

In November of 2011, I attended the 'First Annual International Multidisciplinary Collaborative Conference on Violence Research & Evidence-Based Practice: Sexual Homicide' where I met the late Dr. Leonard Morgenbesser, an Adjunct faculty member with SUNY Empire State College. After informing Leonard of my success with the data collaborative, I became known to him as "the database guy". We discussed an idea to continue the efforts of the SHEISC using the conference as a "jumping off point".

On November 17, 2011, we began building the "as yet unnamed" collaborative using the members of the SHEISC‏ and the conference speakers as the foundation. Since some of the conference speakers were already members of the SHEISC, getting things moving was less complicated. Throughout the month of December, I began recruiting additional members to the newly enhanced collaborative. On January 5th, 2012, the collaborative was given the official name of the 'Multidisciplinary Collaborative on Sexual Crime and Violence' (MCSCV). To date, I have recruited close to 90 of the 102 group members.

In early January of 2012, I introduced the idea of communicating over a private and secure LinkedIn group. Dr. Wade Myers astutely pointed out that some members would prefer to utilize email rather than LinkedIn as it would require additional technology that could be perceived to be a barrier to communication. Dr. Chris Kunkle suggested that an email listserv be set up to accommodate our needs. On January 19, 2012, the listserv went live. To date, both mediums are in use.

The group continued to grow over the next few months as we refined the scope of the topics to discuss and the purpose for the group. Currently, members of the collaborative communicate regularly about serial homicide. Several connections have been made outside of the virtual group. In an age of restricted budgets, a virtual collaborative such as this should be considered as a means to maintain contact with fellow colleagues.

UPDATE: In 2015, the MCSCV completed the two year transition to Northeastern University and was renamed the Atypical Homicide Research Group after incorporating the topic of mass homicide

An Attempt to Explain the Decline in Instances of Serial Homicide

The following ideas are an attempt to explain the decline in serial homicide, appear in no particular order and may have little to no impact on the overall rate of serial homicide:

The Proliferation of Technology

• surveillance cameras, home security systems and GPS devices allow an offender less opportunity to abduct a victim without being tracked or traced
• Man stalked 7-year-old girl, took inappropriate photo of her in grocery store - ow.ly/nJ3pr
• 24 hour news coverage, social media and online news outlets disseminate information on most murders and cases of missing women allowing the public to make connections and contribute to investigations
• The Federal Motor Carrier Safety Administration — in charge of regulating the trucking industry — is very likely to soon mandate that all truckers install electronic logging devices
• cellular phones ensure that potential victims are less likely to remain lost in unsafe areas
• cellular phones provide the availability of immediate law enforcement action
• stories highlighting offenders who abuse animals receive news coverage, allowing more opportunities for either law enforcement or mental health interventions
• shine.yahoo.com/pets/man-arrested-animal-cruelty-puppy-doe-case-211100031.html 
• better medical care converts some potential homicides into attempted murders/aggravated assaults – precluding offenders from attaining “serial murder” status
• technology is keeping kids indoors, not playing around outside without supervision
• social media allows potential victims to screen strangers before befriending them
• social media has placed an emphasis on our own personal networks, limiting our interactions with strangers
• personal computers offer a comprehensive record of our daily lives, ensuring that law enforcement is made aware of potential foul play much sooner
• potential victims are more interconnected; cataloging our digital relationships allows for outside parties to monitor our behavior, increasing the likelihood of receiving scrutiny for meetings with strangers
• offenders may post their intentions to social media sites before they enact their plan, allowing time for others to intervene
• http://www.thedailybeast.com/articles/2012/02/27/facebook-post-by-chardon-ohio-high-school-shooting-suspect-t-j-lane.html

Better Law Enforcement

·         police consider the possibility of serial offenders more quickly than in the past 

·     cases are linked more rapidly due to increased communication between departments
·     law enforcement databases are more widely used and linked together
·     more would be serial killers are apprehended after one or two murders
               http://www.ocala.com/article/20060112/NEWS/201120394

·         ex-law enforcement agents maintain companies that offer behavioral consulting services, ensuring that police are well informed and trained on offender behavior

·         police are more apt to utilize assistance from the public in identifying these offenders

Education and Vigilance

• due to the overwhelming presence of serial killers in entertainment media, potential victims overestimate their real world presence, leading to an increased level of awareness of the phenomenon
• criminologists have educated potential victims on the traits serial offenders possess, e.g psychopathy
• potential victims know how to better identify warning signs and pay attention to situational cues
• the words “creeper” and “stalker” are commonplace in the lexicon of young women
• due to roadside services, such as AAA, potential victims no longer must rely on strangers for assistance, greatly decreasing their odds of being victimized

Change in Demographics

• http://slatest.slate.com/posts/2012/05/17/census_whites_account_for_less_than_half_of_u_s_births_for_the_first_time_in_history_.html
• non-caucasian serial killers are less rare than in the past but by increasing those individual's share of the population, the rate of serial homicide may further decrease

Other Outlets

• the era of free internet pornography has ushered in the means for potential offenders to meet their needs in an alternative, non-violent manner
• consensual deviant sexual encounters have become more mainstream and widely accepted
• increased use of sex trafficking victims by serial offenders removes the need for potential offenders to eliminate witnesses
• increase in number of offenders who keep kidnapped victims captive for repeated assaults
• websites connect potential offenders with access to discreet currency for sex exchanges without the threat of law enforcement interference, making the availability for willing partners more common and removing the need for offenders to victimize unwilling participants

Increased Use of Mental Health Services

• the stigma surrounding therapy has been lessened
• mental health issues are taken more seriously by society
• paraphilias are more apt to be understood as signs of future issues
• http://woodbury.patch.com/articles/courts-commit-woodbury-man-who-wanted-to-be-a-serial-killer-to-a-mental-hospital
• pharmacological drugs are frequently prescribed to aid in the coping process
• court ordered therapy is more frequently mandated
• better methods exist to identify and treat sexual offenders

Use of Parole Less Common

• More would be serial offenders remain incarcerated for lesser crimes for longer periods of time
• http://www.guardian.co.uk/world/feedarticle/10134510

Change in Social/Cultural Factors

• widespread knowledge of the dangers/illegality of the practice of hitchhiking
• decrease in use of corporal punishment by parents/zero tolerance for parental abuse
• decrease in the amount of children born to unfit parents

Serial Murder is Less Infamous

• serial homicide is no longer viewed as the short path to celebrity it once was
• serial murderers are a commonplace aspect of society, leading to less sensationalism and a decrease in copycat offenders
• some offenders prefer to utilize other means to accomplish their goals, as we have seen with the increase in “spree type” killings, those that are initially high in intensity but bring a quick burnout and capture

The True Prevalence May Be Unknown

• DNA backlogs mask the true prevalence of serial homicide
  
  • offenders who have committed more than one murder have yet to be linked to their crimes

·         various interpretations of the serial murder definition may lead to erroneous conclusions

·         failure to incorporate those who murder two victims impacts serial murder research

·         most offender data ignores unsolved cases, taking only solved cases into account

·         serial killers may be more aware of forensic procedures meant to capture them and therefore institute methods to maneuver around those procedures, avoiding detection for longer periods of time

Is serial killing a ‘black and white’ issue?

With the discovery of the murders in Ohio allegedly committed by Michael Madison comes speculation that a new type of criminal has emerged – the African American serial killer.

Even though at least one out of every two serial killers is African American (Yaksic, 2006; Hickey, 2013), one of the most recurrent stereotypes in the field of serial homicide research is that the majority of serial killers are Caucasian. It is now known that several African American serial killers – Kermit Gosnell, Lonnie Franklin, Lorenzo Gilyard, Carl Watts, Chester Turner and Vincent Groves – rank among the most prolific in their respective states. Even by conservative estimates, African Americans have historically been overrepresented among serial murderers based on their share of the population (Kuhns and Coston, 2005). Despite these facts, African American serial killers have enjoyed some measure of freedom to commit their crimes in the absence of consistent intervention from law enforcement, rigorous study by academic researchers or intrusion by the news media.

Fortunately, much has been done in recent years to curtail the pervasive belief that the race of serial killers is a ‘black and white’ issue.

Several researchers have documented the African American serial killer’s ability to operate with impunity. Since the public has perceived black murderers that produce black victims as merely ‘urban homicide’, such offenders can be easily ignored and overlooked (Jenkins, 1993). The false perception that black sexual serial killers are rare makes it easier for them to go undetected for a longer period of time (Geberth, 2012). Serial killings of black victims, especially those who are impoverished and marginalized politically, are less likely to be connected, prioritized for investigation and subsequently solved (Fox, 2012). Little has been done to bring cases dealing with African American serial killers to the public’s attention (Hickey, 2013).

In order to understand why the prevalence of African American serial killers has been misrepresented among law enforcement, one must consult a 1985 report titled The Men Who Murdered that summarized the findings from interviews conducted by two FBI profilers with twenty five predominantly Caucasian serial killers (Ressler and Burgess, 1985). Subsequent criminological concepts and law enforcement techniques were based on that non-random sample and are currently still in use. Although the FBI recently stated that serial killers are a diverse group (Morton and Hilts, 2008), the ramifications from the agent’s findings in 1985 are still continuously affecting cases.

Countless hours were dedicated to hunting a Caucasian man for the murders of seven mostly Caucasian women in the Baton Rouge area between 1993 and 2003. Since law enforcement agents were operating under the assumption that murders are typically intraracial events, it came as a surprise when Derrick Todd Lee, the African American man responsible for this string of murders, was apprehended. This case highlights the dangers of abiding by a profile based on outmoded data. In their research on the sexually sadistic serial killer, Warren et al. (1996) erroneously proclaim that Caucasians are over represented in fantasy driven sexually sadistic serial crimes because of a different process of development of sexual identity among the two groups, a different potential for developing paraphilic preferences, or both. Leach and Meloy (1999) state that what is unusual in the case of Ray Shawn Jackson is that most sexual sadists in published studies are Caucasian males, making Jackson "racially unusual" as a sexual sadist. Unbeknownst to most, there have been several examples of offenders – Calvin Jackson, John Floyd Thomas, Jake Bird and Carlton Gary – who murdered victims outside of their own race and for sexually sadistic purposes.

During the hunt for the ‘DC Snipers’ in 2002, most criminologists believed that a "white, lone-wolf type” offender was responsible for the atrocities that were carried out by two African American men. The Lee and ‘DC Snipers’ cases demonstrate that there can never be a behavioral profile that accurately determines an offender's race since African American and Caucasian serial killers behave in strikingly similar ways. Both kill for the same reasons and both become killers due to a comparable mix of biological and psychosocial elements. Obstinate poverty and plight may play a role as a causal factor in African American serial killings, but it is rarely the offender's sole motivation to commit serial murders. While African American serial killers do more often than Caucasian serial killers target elderly victims (Safarik et al., 2002), kill those known to them, use recreational drugs to lure their victims and arson to conceal their crimes, the underpinning desire to dominate and control others is shared by both sets of murderers (Yaksic, 2006).

Over the last decade, law enforcement agencies have continually improved their response to instances of serial homicide involving African Americans. The allegations of racial prejudice that have been leveled at one time against police organizations for taking crimes involving white victims more seriously have declined in recent years mainly because the demographics of today’s police force better reflect those of the community (Jenkins, 1993). Police regularly attend conferences and trainings that deal with techniques to pursue and apprehend serial homicide offenders and the impact that such offenders have on the community. Police are also now better equipped to link unsolved homicides due to better communication mechanisms and advances in DNA technology.

Those who report on the instances of serial homicide have been accused of ignoring matters that involve race due to its demonstrative and controversial nature. In response to these claims, researchers have collected hordes of empirically collected data on African American serial killers in recent years (Jenkins, 1993; Walsh, 2005; Peterson, 2006; Yaksic, 2006; Branson, 2012; Cottrell, 2012; Fox, 2012; Aamodt, 2013; Hickey, 2013; McClellan, 2013; Lester and White, 2014). Others have highlighted case studies detailing the crimes of African American serial killers (Keppel, 1995; Kreuger, 1998; Leach and Meloy, 1999; Beasley, 2004; Kuhn and Coston, 2004; Morton, 2010; Reavis, 2011). The lives of two serial killers, one African American and the other Caucasian, have also been compared and contrasted (Wolf and Lavezzi, 2007).

It has been said that, in issues related to police and criminal psychology, it seems that people want simple answers and the media are happy to oblige this desire (Aamodt, 2008). Once the race of the ‘DC Snipers’ became known after weeks of national television coverage, media outlets realized the capabilities of African American serial killers and have covered these cases more liberally than in the past. The apprehension of Anthony Wayne Smith, the former Oakland Raider who stands accused of four Los Angeles area murders, ushered the media into concluding that serial killers can be of any race or occupation. The wide coverage received by suspected serial killer Darren Deon Vann alludes to a slow disintegration of the old adage that the media ignores black killers with black victims. In these instances, the media has determined, rightly so, that there are no simple answers when race and criminality intersect.

Coupled with the discovery of long dormant serial killers due to advances in DNA technology and the newfound interest from the news media, the sudden emergence and juxtaposition of Anthony Sowell and Michael Madison in Ohio has contributed to the appearance of a surge in murders committed by African American serial killers. After analyzing empirically collected serial homicide data, the results indicate that not only have African American serial killers existed alongside their Caucasian counterparts for all of history, but that the occurrence of serial murder itself is in decline (Fox, 2012; Aamodt & Surrette, 2013). Academic researchers agree that we are not in the throes of an African American serial murder epidemic. Rather, more attention is being paid to a once neglected subset of killer.

To refute and invalidate the persistent claim that African American serial killers are disadvantaged by inferior intelligence which dissuades them from engaging in serial murder campaigns, one must only analyze the recent case of Jason Thomas Scott. Scott's crimes are regarded as one of the "most complex" cases that Maryland law enforcement officials had seen as he engaged in a series of forensic countermeasures to ensure that he would remain at large. African American serial killers are every bit as capable as their Caucasian counterparts but they are also aided by societal stereotypes that benefit their longevity as killers. The acknowledgement of the presence of African American serial killers and their abilities will inevitably deliver with it better methods of detection and new measures of safety for the public.

Contributions to Serial Murderers and Their Victims (6th edition)

The following can be found in the preface of Serial Murderers and Their Victims (6th edition):

Every once in a while I come across someone in my career who seems to appear on my doorstep wanting to help and collaborate. Enzo Yaksic did just that and offered to collect serial murder cases for me to use in updating my tables for 2004 - 2011 found in chapters 7 - 10. A special thanks to Dr. Mike Aamodt of Radford University, Virginia, and Dr. John White of Richard Stockton College Center for Public Safety and Security, New Jersey, for their help in identifying the race of specific serial killers who appear in the sixth edition updates constructed by Enzo. He also prepared the original profile for the Samuel Dixon case that was facilitated by the use of the Serial Homicide Expertise and Information Sharing Collaborative. Enzo, thank you so much for your assistance. Your passion for the field of forensics is exactly what is needed to further the work. Working with you has been most enjoyable, and I am sure that we will collaborate for many years to come. Also, a special thanks to James A. Reavis, Psy.D, Director of Forensic Services at the Relationship Training Institute in San Diego, California, for his assistance in developing the profile of Samuel Dixon. Your collaboration is much appreciated.

Current data of all new serial killers in the United States from 2004 - 2011 are provided in a very readable format. Analysis of these data reveal some very significant trends and changes in the demographics of serial murder. This is one of the most important updates in this sixth edition not only because it debunks stereotypes of serial killers, but it also underscores the fact that many victims of serial murder are being ignored by the media. The significant increase in serial killers who are black in the United States is contrary to the stereotype that the majority are white offenders.

About the SHEISC Team

Over the past forty years, general knowledge of serial killers has been derived from self-selected sources; offender interviews and case studies. A varied group of individuals gathered this data but operated in information silos due to competing interests. This lack of collaboration led to the influence of anecdotal evidence on public statements made about serial killers. Today, a burgeoning “serial murder industry” amplifies these myths and stereotypes, packaging them as entertainment. The ‘true crime’ genre has fostered a new generation of researchers that promulgate similar falsehoods. In response to this misinformation, Enzo Yaksic ushered a subset of the criminal justice community into the digital workspace to synchronize and standardize serial homicide data collection efforts. This unprecedented initiative, named the Serial Homicide Expertise and Information Sharing Collaborative (SHEISC), was formed in August 2010.

Leveraging connections made while interning at the Federal Bureau of Investigation Academy, Enzo built a network comprised of those with experience maintaining serial homicide datasets. Each member - Mike Aamodt, James Alan Fox, Eric Hickey, Ronald Hinch, Brigadier Gérard Labuschagne, Jack Levin, Janet McClellan, Bryan Nelson, Michael Newton, Kenna Quinet, John White - compiled and contributed their own data to one central location, henceforth known as the ‘SHEISC Joint Serial Killer Database’. In 2013, this dataset was merged with the ‘Radford/FGCU Serial Killer Database Research Project’ to bolster the creation of a national serial homicide offender database, a call made to the field three years prior by Enzo. For additional details and biographies, please see below.

The baseline data was compiled by Enzo Yaksic for James Alan Fox's Extreme Killing: Understanding Serial and Mass Murder. This initial dataset contained records on approximately two thousand US based serial killers and was built over the course of the past ten years. Seven other datasets from the following contributors were combined with Enzo's initial data to form the 'SHEISC Joint Serial Killer Database': 

Mike Aamodt is professor emeritus of psychology at Radford University in Radford, Virginia. Mike is the founder of the Serial Killer Information Center. Mike contributed his entire dataset to this effort.

Eric Hickey is the Dean of Alliant International University’s California School of Forensic Studies. Eric has authored numerous scholarly works including Serial Murderers and Their Victims. Eric contributed his entire dataset to this effort.

John White is an Associate Professor of Psychology at Richard Stockton College. John recently authored The Utilization of Forensic Science and Criminal Profiling for Capturing Serial Killers. John contributed his entire dataset to this effort. 

Kenna Quinet is an Associate Professor of Criminal Justice, Law and Public Safety at the School of Public and Environmental Affairs at Indiana University-Purdue University Indianapolis. Kenna's research focuses on various aspects of homicide including serial and mass homicides, missing persons, unidentified dead and prostitutes as serial homicide victims. Most recently, she is a co-author of The Will To Kill: Making Sense of Senseless Murder with Jamie Fox and Jack Levin. Kenna authored Prostitutes as Victims of Serial Homicide: Trends and Case Characteristics from 1970-2009 and The Missing Missing: Towards a Quantification of Serial Murder Victimization in the United States. Kenna was the first to contribute her entire dataset to this effort. 

Ronald Hinch is a Professor at the University of Ontario Institute of Technology. Ron wrote the seminal work Researching Serial Murder in 1998. Prior to joining UOIT he was a faculty member at the University of Guelph in Ontario, where he served as Chair of the Department of Sociology and Anthropology. Ron contributed his entire dataset to this effort.

Janet McClellan is the Chair of the Masters in Criminal Justice and Homeland Security & Disaster Management in the School of Public Services with Kaplan University.  Janet recently authored Erontophontophilia: Investigating Violent Sexualized Homicides and Delivery Drivers and Long-Haul Truckers: Traveling Serial Murderers. Janet contributed her entire dataset of African American serial killers to this effort.  

Bryan Nelson is a Forensic Mental Health Specialist with the Forensic Conditional Release Program (CONREP) in California.  Bryan is a treatment provider for individuals who have been found Not Guilty by Reason of Insanity or deemed a Mentally Disordered Offender with specialization working with sexual offenders.  The role of fantasy in the development of serial murder offenders has been a research interest for Bryan for many years. Bryan contributed his entire dataset to this effort. 

Michael Newton is the author of the first and second editions of The Encyclopedia of Serial Killers. Michael contributed his entire dataset, in paper form, to this effort. Enzo copied the dataset to an Excel file so it could be merged with the others.  

Wade C. Myers is a professor of Psychiatry and Human Behavior at the Warren Alpert Medical School of Brown University and Director of Forensic Psychiatry at Rhode Island Hospital. Wade has written extensively on the issue of juvenile killers, including the book, Juvenile Sexual Homicide. Wade provided information on one case to this effort. 

Tom Hargrove is a Database Research Consultant with E.W. Scripps Co. and recipient of the national Philip Meyer Prize for journalism for creating a computer algorithm that identifies homicide clusters with a high probability of serial murder. Information on the project can be found here: www.scrippsnews.com/projects/serial-killers Tom was instrumental in securing the release of summary unsolved homicides data from the ViCAP system. Tom provided information on one case to this effort. 

Kenneth Morris is a Criminal Profiler with the Virginia State Police. Ken is a graduate of the International Criminal Investigative Analysis Fellowship. Ken provided 10 cases to this effort.

Enzo also copied the dataset from Justin Cottrell's book The Rise of the Black Serial Killer into an Excel file so it could be merged with the others.

Although this dataset only encompasses serial murders committed within the US, two researchers contributed their data to this effort: 

Brigadier Gérard Labuschagne contributed 115 cases of South African serial killers to this effort.

The data from Lee Mellor's Cold North Killers: Canadian Serial Murder was copied for this effort.

It should be noted that others were approached during the planning stages of the collaborative.

Dr. Steve Egger has graciously offered to contribute his dataset of 3,000 serial killers to the effort. Dr. Charisse T.M. Coston maintains a dataset and has committed to sharing it with the SHEISC.

In October 2010, Enzo contacted Vernon Geberth, author of Antisocial Personality Disorder, Sexual Sadism, Malignant Narcissism and Serial Murder, in an effort to request the data used in the article. Geberth stated that the original data exists only in hard copy form due to a complication with the computer where the "thesis materials" were stored. Further requests for the paper copies were ignored. When asked for his database, Elliot Leyton stated that he did not have a dataset that he could provide towards the effort. In September 2010, Louis Schlesinger simply stated, "Sorry, can't share data, good luck."

In April 2011, Dr. David Canter stated that since the 'Missen Corpus of Serial Killer Data' was purchased for 20,000 dollars, it can "only be made available to bona fide researchers at considerable cost." In September 2012, Dr. Maurice Godwin, who received his PhD from Dr. Canter's program, attached a 2,500 dollar price tag to a different dataset that he maintains. Dr. Godwin's justification for the cost arose from the fact that, unlike the data in the Radford/FGCU Serial Killer Database, his information was gathered directly from police files (care of Robert Keppel/HITS). Dr. Godwin also added that the 'Missen Corpus of Serial Killer Data' was compiled from "anecdotal" sources, mostly detective magazines and true crime books. Given the open-source nature of our serial homicide data sharing effort, we neglected to pursue the avenue of purchasing other datasets.

Dr. Gabrielle Salfati noted that legal and ethical issues as well as Institutional Review Board and police restrictions can limit a researcher's access to raw data. Affiliation with a university or other recognized agency was also suggested to increase the likelihood that agencies will provide data.

Dr. Matt DeLisi provided the data used in his Multiple Homicide Offenders: Offense Characteristics, Social Correlates, and Criminal Careers paper but the IRB at Iowa State University required that the data be de-identified so all names were removed after the dataset was created.

In July 2011, Enzo partnered with Scripps Howard News Service investigative reporter Thomas Hargrove to file a Freedom of Information Act request to obtain the names and demographics of all serial killers known to the National Center for the Analysis of Violent Crime. Even though Drs. Schlesinger, Warren and Salfati consistently reference data gathered from FBI files and agents of the NCAVC write academic papers based on said information, the FBI claimed to “not maintain a running list of serial killers.” As an example of the pitfalls and pratfalls endemic to this data gathering venture, when Enzo asked Dr. Kirk Heilbrun for the data used in Comparing Single and Serial Homicide Offenses, he stated that "the database in question actually belongs to the FBI, so it's not mine to contribute."
