Cases in Point: John Wayne Gacy & Gary Leon Ridgway
John Wayne Gacy & Gary Leon Ridgway
There is a great deal of confusion and myth surrounding serial killers and the investigative processes used by law enforcement. Much of this myth and confusion has been caused and promulgated by the media. There is also an extreme lack of professional expertise in serial murder due to the fact that serial killers are so rare that it is difficult for any one professional to become an expert in this field. For these reasons, the FBI’s Behavioral Analysis Unit (BAU) has identified specific investigative practices as being successful investigative techniques. When one examines an individual serial killer, these investigative techniques become apparent in their utility.
To understand the application of the BAU’s investigative practices, one can examine the case of the serial killer John Wayne Gacy. One of the most difficult points for law enforcement with investigating serial killers is the fact that law enforcement is often prone to the same myths, misconceptions, and biases that the general public succumb. The BAU states:
Law enforcement professionals are subject to the same misinformation from a different source: the use of anecdotal information. Professionals involved in serial murder cases, such as investigators, prosecutors, and pathologists may have limited exposure to serial murder. Their experience may be based upon a single murder series, and the factors, in that case, are extrapolated to other serial murders. As a result, certain stereotypes and misconceptions take root regarding the nature of serial murder and the characteristics of serial killers (US Department of Justice ).
This factor can have a blinding effect on law enforcement. The BAU identifies the most important investigative practice to be the identification process. One can readily see the importance of this point in the investigative process in the case of John Wayne Gacy. Gacy, between 1972 and 1978, raped, tortured, and killed a known thirty-three young men (Federal Bureau of Investigation). Gacy was able to kill so many individuals primarily because he was not identified as a serial killer until 1978. In 1976 a family member of one of the victims urged police to investigate Gacy and twice after that incident Gacy would be accused by two individuals of rape and the police failed to act (Federal Bureau of Investigation). This happened despite the fact that Gacy had already served time in prison for sodomizing a young man.
The reason that Gacy was allowed to continue killing was due to the fact that, in many instances, police lack the investigative skill or means to identify a serial killer. Due to the fact that serial killers are rare, the police found the claims of the persons who accused Gacy to lack credibility. As well, the incidents were not connected so the police who investigated the second complaint had no idea that there was a prior complaint. The BAU cites “lack of communication between law enforcement agencies and differing records management systems impede the linkage of cases to a common offender” (US Department of Justice ).
Despite the fact that the Gacy case was impeded by not recognizing him as a serial killer, the leadership of the case was extremely proficient. The investigators of the case were able to begin piecing together the Gacy murders and the individual reports from families and victims very quickly. The lead investigators were both competent homicide detectives and this was exactly what was needed according to the BAU.
In serial murder cases, the actual investigation should be directed by competent, homicide investigators, who have the experience to direct and focus the investigative process. Law enforcement administrators should not run the investigation but rather ensure that the investigators have the resources to do their job. Supervisors should also act as buffers between investigators and the other levels of command (US Department of Justice ).
Once investigators began focusing on Gacy, they were allowed to handle the case with very little pressure from superiors and from the public. Gacy was arrested after several months of investigation and a confession was obtained after his arrest. The investigation of Gacy included the questioning of victims and associates of Gacy which allowed for investigators to obtain search warrants in order to search for bodies in the Gacy residents. In many ways, the Gacy investigation was a model serial killer investigation because there were no strong or public personalities involved and there was little micromanagement of the investigation process (Federal Bureau of Investigation).
Another area of success in the Gacy case was the use of competent analytical tools. The investigators were competent in many of the areas such as “crime scene analysis, offender profiles, case linkage analysis, interview strategies, and prosecution strategy.” (US Department of Justice )For example, the lead investigators entered the Gacy home at his invitation and while one investigator kept Gacy busy the other was able to go into the bathroom where he smelled decomposition coming from the air vents. Prior visits from police were unable to detect this smell (Federal Bureau of Investigation). Investigators were also able to create accurate timelines of victims and link these cases in a meaningful way for the prosecution to use at trial. Investigators were able to obtain future search warrants due to their ability to accurately investigate the scene. The competence of investigators and their use of analytic tools was an important factor in bringing Gacy to justice. This is especially true during this time period when DNA testing was not being used. The investigation depended strongly on the ability of investigators to link Gacy with victims and discover other forensic evidence such as victim belongings and match them to the victims using family and acquaintances.
The fact that investigators were well trained and had operational discretion over the Gacy case highlights the need for serial investigations to processed within specific parameters and standards. The Gacy cases show how identification is perhaps the most important aspect of the serial killer investigation but the case also highlights how a case should be conducted once the serial killer is known.
One of the major issues which often occurs during serial killer investigations is what is known as the talking head phenomena. This is the issue of self-proclaimed experts who are given credibility by the media in serial killer cases. These so-called authorities often appear on television and in other media outlets and speculate concerning the motives and the causes of the serial killer as well as possible characteristics of the offender despite having no direct involvement with the case (US Department of Justice ). Unfortunately, the talking heads can often create barriers to the investigation because they perpetuate myths and misperceptions that impair nonexperts in law enforcement. Some of the myths perpetuated by these individuals and other media outlets include:
Except for being white and having sex as a part of his modus operendi, Gacy did not exhibit any of the other myths perpetuated in media concerning serial killers. In fact, Gacy was described as being a likable and respected member of the community (Federal Bureau of Investigation). He was active in community affairs. Gacy also did not operate across state lines nor was he incapable of halting his murders. Gacy would stop for periods of time and then begin murdering again. Certainly, Gacy did not desire to get caught judging from the lengths he went to avoid capture (Federal Bureau of Investigation).
The lack of media sensation at the beginning of the Gacy case may have been a significant factor in his investigation and arrest. When one looks at other cases such as the Green River Killer, who arguably was as normal in appearance as Gacy, was recognized by police in the early 1980s.
The Green River Killer, Gary Ridgeway, confessed to killing 48 women over a twenty-year time period in the Seattle, Washington area. He had been married three times and was still married at the time of his arrest. He was employed as a truck painter for thirty-two years. He attended church regularly, read the Bible at home and at work, and talked about religion with co-workers (US Department of Justice ).
The Green River Killer was spotlighted in the news and a task force was formed in the early 80s but Gary Leon Ridgway would not be apprehended until 2001. The length of time involved in apprehending Ridgway was due to the fact that he did not fit the profile myths that are typically perpetrated by media and by so called experts (US Department of Justice ).
Another glaring example of this problem can be seen in the Atlanta Murders of 1979 to 1981. Wayne Williams was a black serial killer and for many months investigators were looking for a white male until one investigator realized that the killer had to be black to enter the all black areas where the murders were taking place. This factor impeded the investigation for a long time but once investigators realized they were looking for the wrong subject they were able to begin refocusing their investigation.
It is cases such as Gacy’s and other serial murders that reflect both beneficial and negative practices. The fact that serial killing is rare dictates that officers need more training and more standardized practices for processing serial murders in order to maintain the highest level of case proficiency. While John Wayne Gacy was a failure in the aspect of law enforcement recognizing the serial murders, his case was also a model for how the investigative process should be handled. In the future law enforcement will continue to improve as units such as the BAU continue to collect data and provide more effective practices in the investigation of serial murders.
